Quick answer: An Analytical Chemistry response to reviewers is a point-by-point rebuttal that quotes every comment, answers it directly, and uses the exact page and line number to specify where each change lives in the revised manuscript.
The decisive Analytical Chemistry test is the measurement-science novelty bar: ACS scope rejects a paper that is a routine extension or minor technical improvement of a published method, so when a reviewer calls the work incremental you answer with a head-to-head figures-of-merit comparison to the prior best method, not more sample types. A major-revision round typically runs 6 to 12 weeks.

What does an Analytical Chemistry response to reviewers require?
The Manusights Analytical Chemistry rebuttal scan. This guide explains what the handling editor and the typically two to three measurement-science reviewers look for in an Analytical Chemistry rebuttal. The scan tells you whether YOUR response letter clears that bar before it goes back through ACS Paragon Plus. In our pre-submission review work with Analytical Chemistry manuscripts, the rebuttals that stall are almost always the ones that treat a measurement-science novelty concern as a writing problem rather than a missing-data problem. Your manuscript is never used to train any AI model, and we erase it within 24 hours of the scan.
Three things make an Analytical Chemistry rebuttal different from a generic one:
- A measurement-science novelty gate at revision, not just at desk. The ACS author guidelines state that papers dealing with established analytical methods must offer a significantly improved, original application, a noteworthy improvement, or results on an important analyte. A reviewer can send a paper back specifically because the advance over the prior method is thin.
- A mandatory itemized format. ACS revision instructions require an itemized list of changes with a response to each comment from the editor and each reviewer. A free-form letter that answers comments in bulk fails the format outright.
- A high bar for figures of merit and real-sample validation. A claimed performance gain that does not appear as numbers in a validation table converts a major revision into a rejection.
How this guide was produced
We reviewed Analytical Chemistry's own ACS author guidelines and scope language, then we checked the revision-format and response-letter requirements against the ACS revision instructions and ACS's published advice on responding to reviewer comments, and compared both against our own pre-submission reviews of Analytical Chemistry-targeted resubmissions. Every claim below traces to a primary source or our review corpus, and the sources used are listed at the end.
One thing the author guidelines never say out loud: Analytical Chemistry editors screen hard for a genuine measurement-science advance before review, and that same novelty-plus-validation expectation does not relax at the revision stage. The journal reports an impact factor of 6.7 (JCR 2024), an acceptance rate around 35 to 45%, and a median first decision near 90 to 120 days. Those numbers tell you the revision bar is real and the clock is not short.

The copyable Analytical Chemistry rebuttal template
Analytical Chemistry reviewers read your rebuttal against the revised manuscript and against each other's reports, so a clean, scannable structure that points straight to the new validation data is doing real work. Copy this skeleton, then replace the bracketed text with your own changes. Keep the reviewer text and your reply in two distinct fonts or colors, and route every analytical claim to a specific table or figure.
Dear Editor,
Thank you for the opportunity to revise our manuscript the manuscript title
(ac-[ID]). We are grateful to the reviewers for their careful
reports. In response, we have added [the missing figures of merit /
real-sample validation / head-to-head comparison], revised Figure [N],
and added a complete validation table to the Supporting Information. An
itemized point-by-point response follows; reviewer comments are in bold
and our replies in plain text, with revised-manuscript page and line
numbers given for every change.
----------------------------------------------------------------
Reviewer 1
Comment 1.1: "The advance over the existing method is not
quantified."
Response: We agree the comparison was not explicit. We have added a
head-to-head benchmark against [prior method] in new Table 2: the LOD
improves from [X] to [Y] and the analysis time drops from [A] to [B].
Changed text appears on page 6, lines 11 to 22.
Comment 1.2: "Figures of merit are incomplete; LOQ and inter-day
precision are missing."
Response: We have added LOQ, linear dynamic range, and intra-day and
inter-day precision (RSD) to a complete figures-of-merit table (new
Supplementary Table S3). See page 12, lines 4 to 10, and the SI.
----------------------------------------------------------------
Reviewer 2
Comment 2.1: "Validation uses only standard solutions, not a real
matrix."
Response: We have validated the method in [real matrix, e.g. serum /
river water] with spike-recovery at three levels (89 to 104%, new
Table 3) and added matrix-effect data to the SI. Revised text is on
page 9, lines 2 to 15.
----------------------------------------------------------------
Reviewer 3
Comment 3.1: "Selectivity against [interferent] is not demonstrated."
Response: We have added a selectivity study against [interferents]
(new Figure 4) showing [result]. See page 10, lines 18 to 24.
We believe the revised manuscript now establishes the measurement-
science advance with complete validation, and we look forward to your
decision.
Sincerely,
[Corresponding author, on behalf of all authors]An Analytical Chemistry reviewer scans this skeleton for four signals:
- A letter to the handling editor that names the major changes up front.
- A Reviewer 1 / 2 / 3 structure that mirrors the reports.
- Explicit action language ("we have added", "we have validated", "we have revised").
- A page and line reference for every change.
The analytical-specific layer sits on top of all four: each reply routes to a named validation table or calibration figure, because at this journal a fix that does not show up in the data is not a fix.
The page-and-line rule: cite the location of every change
At Analytical Chemistry, the location you point to is usually a number, not a sentence. Give the exact page and line in the revised manuscript for every change, and name the specific validation table, calibration figure, or Supporting Information file that now carries the new data. ACS's own advice on responding to reviewer comments tells authors to reproduce the comment, indicate the change, and specify where it lives by page and paragraph; ACS also asks for a marked-up version uploaded as Supporting Information for Review Only.
This is the single most-cited rebuttal failure at Analytical Chemistry, and on a method paper the cost is sharper than usual:
- A reviewer who has to hunt for your new figures-of-merit table reads the silence as evasion on exactly the data they asked for.
- A reviewer who can jump straight to page 12, lines 4 to 10, and Supplementary Table S3 confirms the LOD and precision in seconds and re-reads the rest more generously.
Two hard rules: never write "we have addressed this in the manuscript" without a location, and never claim a validation result lives in the paper when it lives only in the rebuttal letter. Use line numbers from the revised file, not the original.
Reviewer-text vs author-response typography
Keep the reviewer's words and your reply visually separate. Put each reviewer comment in bold or a colored text box, and set your response in plain regular text directly beneath it.
The reason is specific to this journal. An Analytical Chemistry reviewer is not skimming for tone; they are cross-checking each numerical claim against a calibration curve or a precision table. When comment and reply blur into one block, the figures-of-merit answer you worked weeks to produce gets lost in the layout.
A clean two-font or two-color format also does double duty. Because ACS revision instructions ask for an itemized list of changes, that visual structure is what turns your letter into the itemized document the editor expects rather than a wall of prose.
Tone calibration: how to phrase the hard replies
The reviewers see your tone across every comment, and on a method paper the hardest comments are the ones questioning whether your advance is real. A defensive reply to an analytical-rigor request is the fastest way to lose a reviewer who controls your re-review. Calibrate.
Bad (defensive or vague) | Better (substantive and gracious) |
|---|---|
"The novelty is obvious from the introduction." | "We agree the advance was not quantified. We have added a head-to-head comparison to [prior method] (Table 2): LOD improves from [X] to [Y], page 6, lines 11 to 22." |
"Standard solutions are sufficient for validation." | "We agree real-matrix validation strengthens the claim. We have added spike-recovery in [matrix] (89 to 104%, Table 3) and matrix-effect data, page 9, lines 2 to 15." |
"We have addressed this concern." | "We have added LOQ, linear range, and inter-day precision to a complete figures-of-merit table (Supplementary Table S3, page 12, lines 4 to 10)." |
"This comparison is outside the scope of our paper." | "We agree this would strengthen the work. Because [reason], we have benchmarked against [the closest available method] in Table 2 and noted the remaining open comparison in the Discussion." |
"Our detection limit is competitive." | "We have added the requested LOD determination by the 3-sigma method (Methods, page 8); the LOD is [value], lower than the [X] reported for [prior method]." |
The pattern that works: concede where the reviewer is right, run the validation, point to the exact table, and push back only on a request that is genuinely out of scope, with a reason and the closest comparison you can make.
The Analytical Chemistry reviewer culture you are writing into
Analytical Chemistry uses single anonymous peer review: the reviewers know who you are, but you do not know them, and a paper is typically evaluated by two to three reviewers chosen for measurement-science expertise. The handling editor integrates the reports and decides what the revision must demonstrate, and may send the revised manuscript to additional reviewers. Your rebuttal is a document read by a panel, not a private exchange with one referee.
The analytical-novelty bar
The defining feature is the analytical-novelty bar. The ACS author guidelines explicitly list, among manuscripts that will not be peer reviewed:
- Work that is a routine extension or minor technical improvement of research already published.
- Work that is narrowly focused without broad appeal across analytical subfields.
- Work on a known method that offers no significant original application, noteworthy improvement, or result on an important analyte.
That is the scope filter at desk, and it is the same filter a reviewer applies at revision. When a reviewer calls your method incremental, they are invoking this exact language, and the only answer that moves them is a quantified measurement-science advance.
The figures-of-merit expectation
Layered on top is the figures-of-merit expectation. For a new method, sensor, or detection scheme, reviewers expect a complete set:
- Limit of detection (LOD) and limit of quantitation (LOQ).
- Linear dynamic range.
- Intra-day and inter-day precision reported as RSD.
- Accuracy or recovery.
- Validation in a real matrix, not only buffer or standard solutions.
Reviewers also expect the Supporting Information to carry the full validation dataset, including calibration curves and matrix-effect data. A manuscript that shows representative spectra with no numerical validation tables draws a major-revision request specifically to supply them. So the bar is a real advance, documented with complete figures of merit, validated in a real sample, and returned on the editor's clock. In practice the editors and reviewers judge whether your rebuttal made the measurement science stronger, not whether it sounds polite.
How the bar differs from neighboring venues
Calibration helps here. A broad-scope methods venue like Nature Methods faces a general-significance bar. At a sister ACS analytical journal such as ACS Sensors, the device-performance and selectivity story carries more weight than at Analytical Chemistry, where the measurement principle and its quantified advance are the protagonist.
The shared ACS revision format (itemized list of changes, response to every comment, marked-up manuscript) travels across the whole portfolio. The substance bar at Analytical Chemistry, though, is specifically a non-incremental advance backed by figures of merit. Treat the rebuttal as a measurement-science argument, not a writing exercise.
Key Insight
At Analytical Chemistry, "the advance is incremental" is a scope verdict, not a tone note. You answer it with a head-to-head figures-of-merit comparison to the prior best method, run in a real matrix, not with more applications or a stronger adjective.
What our Analytical Chemistry rebuttal reviews surface
In our pre-submission review work with Analytical Chemistry submissions, the rebuttals that stall in a second revision round share a small set of recurring weaknesses. These are the same ones reviewers flag at re-review, and each maps to a specific, named failure pattern in the Analytical Chemistry editorial culture. Each is testable against your own draft response before you upload it.
Answering a "what is the analytical advance" question with more applications. The most common and most expensive pattern in our Analytical Chemistry pre-submission reviews is a rebuttal that answers a measurement-science novelty concern by adding more sample types or more use cases. The ACS scope language rejects routine extensions of known methods, so demonstrating the same method on a third matrix does not establish novelty; quantifying how the method beats the prior best approach does.
When a reviewer questions the advance, the fix is a head-to-head comparison with shared figures of merit, not a longer applications section. Across our Analytical Chemistry rebuttal reviews, this mismatch between what the reviewer asked for and what the author delivered is the single strongest predictor of a third round.
Missing or incomplete figures of merit the reviewer requested. Because Analytical Chemistry reviewers cross-check every performance claim against numbers, a rebuttal that responds to a request for LOD, LOQ, or inter-day precision with prose instead of a validation table reads as a dodge.
In our pre-submission review work with Analytical Chemistry manuscripts, responses that claim "improved sensitivity" without a 3-sigma LOD, a linear range, and replicate-based precision consistently draw a re-review comment asking for the missing figures of merit, which adds a round. Put the complete figures-of-merit table in the manuscript or Supporting Information and cite its location in the reply.
Comparison to prior methods omitted. A rebuttal that establishes performance only in isolation, with no quantitative comparison to the closest published method, leaves the reviewer unable to judge whether the advance clears the noteworthy-improvement bar. In our Analytical Chemistry pre-submission reviews, the rebuttals we flag hardest are the ones that report a respectable LOD but never place it next to the prior best LOD, so the reviewer cannot see the gain. Add a comparison table or a sentence with both numbers for every metric the reviewer cares about.
Spiked standards presented as real-sample validation. A recovery study run only in buffer or in a clean standard solution, then described as real-sample validation, is a recurring overstatement. In our pre-submission reviews of Analytical Chemistry resubmissions, responses that conflate spiked-standard recovery with validation in a genuine matrix draw a sharp re-review comment, because matrix effects are exactly what an analytical reviewer is testing for. Validate in the real sample, report the matrix-effect data, and label spiked-standard work as what it is.
Run the comparison, complete the figures of merit, validate in a real matrix, and cite the table for every claim. That four-part discipline is what separates an Analytical Chemistry rebuttal that clears one revision round from one that stalls into a second or third. Check your Analytical Chemistry point-by-point response for these patterns before you submit.

When to comply and when to push back
Situation | Recommended approach at Analytical Chemistry |
|---|---|
Reviewer says the advance over the prior method is not quantified | Comply. Add a head-to-head figures-of-merit comparison; cite the table, page, and line. |
Reviewer asks for missing figures of merit (LOD, LOQ, precision) | Comply. This is the highest-leverage fix; add the complete validation table to the SI. |
Reviewer wants real-sample validation, not standards | Comply. Run spike-recovery in the real matrix and report matrix-effect data. |
Reviewer requests a comparison you genuinely cannot run | Push back with a reason, benchmark against the closest available method, and note the open comparison in the Discussion. |
Reviewer calls the work incremental on a known method | Engage on novelty. Quantify the advance; if you cannot, the scope concern is real and a transfer may serve you better. |
Reviewer questions selectivity against an interferent | Comply. Add the selectivity study; this is core analytical evidence reviewers expect. |

How much work an Analytical Chemistry rebuttal actually takes
Authors consistently underestimate the new-validation effort and overestimate the writing effort. This breakdown is about workload, not the journal's decision clock; for the end-to-end decision schedule, see the Analytical Chemistry review time guide.
Rebuttal task | Where the effort goes | What it costs you |
|---|---|---|
Reading and clustering reviewer reports | Finding the one core concern, usually novelty or validation | A day of careful reading, not a skim |
Running the head-to-head comparison | Benchmarking your method against the prior best with shared metrics | Often the decisive experiment for the novelty verdict |
Completing the figures-of-merit set | LOD, LOQ, linear range, precision, recovery, real-matrix validation | The bulk of the lab work, often several weeks |
Writing the itemized point-by-point replies | One reply plus a table reference and page and line per comment | Less than authors fear once the data exist |
Reconciling overlapping comments | Same numbers for every reviewer who raised a metric | Skipped most often, and it shows |

Honest friction: rejection on revision is real
A major-revision invitation at Analytical Chemistry is not a soft acceptance. The revised manuscript and your point-by-point response go back to the original reviewers, the editor may add reviewers on re-review, and the paper can still end in rejection if the new data do not establish a real measurement-science advance with complete validation. With acceptance running around 35 to 45%, a meaningful share of major revisions do not survive re-review.
The dominant rejection-on-revision cause
Most rejections at the revision stage trace to one move: the author answered a what-is-the-advance question with more applications instead of a quantified comparison to the prior method. The second most common is a figures-of-merit set that is still incomplete, or a recovery study that never left buffer.
Think twice before you resubmit if any of these are true:
- The response uses generic "we have addressed this" language with no page or line numbers.
- A reviewer asked for the analytical advance and you answered with another sample type.
- The figures-of-merit table is still missing LOQ, linear range, or inter-day precision.
- Real-sample validation is still only spiked standards.
- The rebuttal contradicts itself, giving two different LOD or recovery values to two reviewers who raised the same metric.
Fixing these before resubmission is what keeps a second round from becoming a rejection.
Red flags an Analytical Chemistry reviewer spots in seconds
Before you upload, scan your own rebuttal for the patterns that draw an immediate re-review comment. Each is a specific, checkable thing in your draft, not a vague quality dimension.
- A performance claim with no number. Any "improved sensitivity" or "competitive detection limit" with no LOD, LOQ, or precision figure reads as marketing the moment a reviewer looks for the table.
- Applications where an advance was requested. A reviewer asked what makes the method new and the reply adds a third matrix.
This is the single most common cause of a third round at Analytical Chemistry.
- No head-to-head comparison. Figures of merit reported in isolation, with no prior-method benchmark, leave the reviewer unable to judge the gain.
- Buffer recovery sold as real-sample validation. Spike-recovery in a clean standard, described as validation in a genuine matrix, signals you skipped the matrix-effect test the reviewer most cares about.
How does this guide go beyond the Analytical Chemistry author guidelines?
The official ACS guidelines tell you to submit a revised manuscript and that papers must offer a significant original application or noteworthy improvement to be reviewed. What they do not say is the part that changes how you write every reply:
- The novelty filter is reapplied at the revision stage, not only at desk.
- Reviewers expect a complete figures-of-merit table and real-matrix validation as the price of a fix, not a sentence in the Discussion.
- Single anonymous review means a panel cross-checks every number you report.
- An itemized point-by-point response routed to specific tables is the format editors actually expect.
The patterns above come from our pre-submission reviews of Analytical Chemistry rebuttals. They are testable against your own draft today, not theoretical concerns.

Frequently asked questions
Open with a short letter to the handling editor summarizing the major changes, then answer each comment in order under Reviewer 1, Reviewer 2, and Reviewer 3. Quote each reviewer comment in full, state the exact change you made, and give the page and line number in the revised manuscript. ACS revision instructions require an itemized list of changes with a response to each comment from the editor and each reviewer, so leave nothing unanswered.
It means the paper reads as a routine extension or minor technical improvement of a method already published, which is one of the explicit grounds for rejection at Analytical Chemistry. The ACS author guidelines state that papers dealing with established analytical methods need to offer a significantly improved, original application, a noteworthy improvement, or results on an important analyte. You do not fix this by adding more sample types.
For a new method, sensor, or detection scheme, reviewers expect a complete figures-of-merit set: limit of detection, limit of quantitation, linear dynamic range, intra-day and inter-day precision as RSD, accuracy or recovery, and validation in a real matrix rather than only buffer or standard solution.
Yes. A major-revision invitation is not an acceptance. The revised manuscript and your point-by-point response go back to the original reviewers, and the editor may send it to additional reviewers, so the paper can be rejected after re-review if the new data do not establish a real measurement-science advance with complete validation.
Analytical Chemistry uses single anonymous peer review, so reviewers know who you are but you do not know them, and typically two to three reviewers evaluate a paper. Your rebuttal is read by every reviewer assigned to the revision, not just the one who raised a given comment, and the editor may add reviewers on re-review. Keep every overlapping reply consistent, because an inconsistent answer to a figures-of-merit or selectivity point raised by two reviewers reads as evasive.
