Analytical Chemistry 'Under Review': What Each Status Means

ACS does not publish a list of status labels on the pages used for this guide, so treat the labels below as typical examples; your screen may use different wording.

Before the paper reaches external reviewers, an Executive Editor prescreens it and an Analytical Chemistry Associate Editor evaluates whether the analytical method significance warrants Analytical Chemistry's editorial slots. ACS reports a median of 4.3 days to a first editorial decision without peer review. The author guidelines list the grounds for rejection without external review, including work that is outside scope, routine or minor, narrowly focused, or short of the data needed to substantiate the claims. Editors may also suggest a transfer to a sister ACS journal (ACS Measurement Science Au for open-access measurement, ACS Sensors for sensors specialty, JACS for broader chemistry).

Once the paper is in the ACS Publishing Center, it typically moves through these stages:

• ACS Publishing Center administrative processing: The submission is checked for completeness: a manuscript with clearly identified standard sections and figures embedded, Supporting Information as separate files, a cover letter, a conflict-of-interest statement, funding sources, and an ethics statement where animal or human studies are involved. The Analytical Chemistry author guidelines do not list CONSORT, STROBE, or PRISMA checklists, since most submissions are analytical chemistry method development.

• Editorial prescreening and Associate Editor desk screen (median 4.3 days to a first editorial decision without peer review): The Executive Editor and the handling Associate Editor read the paper and evaluate analytical method significance, method-development novelty, characterization rigor, and Analytical Chemistry subspecialty routing.

• Executive Editor prescreening: The Editor-in-Chief writes that every submission is first assessed by one of the Executive Editors to determine whether it fits the scope of Analytical Chemistry and whether its reported advance is significant or distinct enough to warrant further consideration, and that each manuscript that passes is assigned to an Associate Editor with relevant topical experience.

• External reviewer recruitment: Analytical Chemistry Associate Editors invite reviewers with method-development and characterization expertise. ACS publishes no figure for how long recruitment takes.

• Active peer review (36.8-day ACS median to a first decision with peer review): Once reviewers agree to review, the review cycle contributes to the 36.8-day median. The author guidelines say reviewers evaluate manuscripts on originality, technical quality, clarity of presentation, and importance to the field; for analytical-method papers that includes analytical method significance, method-development novelty, characterization rigor, method validation adequacy (LOD/LOQ, calibration, recovery, precision), and reproducibility.

• Editorial synthesis and decision: After reports return, the Associate Editor synthesizes them. The Associate Editor has several decisions for which they can opt, but they generally fall into 3 main categories: accept, reject, and revise. The ACS median from submission to acceptance is 90.2 days, including the time authors take to revise.

• Rejection within 1 to 7 days: Usually an immediate scope mismatch or an editorial desk rejection (ACS's median first editorial decision without peer review is 4.3 days).

• Rejection within 7 to 14 days: Likely an editorial desk rejection that took longer than the 4.3-day median.

A fast rejection usually leaves a scope or significance reason you can act on; the journals to try after an Analytical Chemistry rejection are matched to those reasons.

• Still Under Review after 2 weeks: Strong signal. Paper passed the Analytical Chemistry Associate Editor desk screen.

• Still Under Review after 10 weeks: Reviewer-recruitment or reviewer-report delay. A polite inquiry via the ACS Publishing Center is appropriate.

• Status changes to "Decision Pending": Reports are in; expect a decision within 1 week.

This is the most common anxiety we hear from Analytical Chemistry authors during the active editorial window. The honest answer: no, 5 weeks at Under Review puts you right at ACS's 36.8-day (about 5 week) median for a first decision with peer review. Reports may already be in editorial synthesis with the Associate Editor preparing the recommendation. Most reviewer-driven delays come from reviewer-recruitment timing for method-development subspecialty experts rather than slow reviews.

If the portal still says Under Review at the 8-week mark, the most likely explanation is that one of the assigned reviewers asked for an extension and the Associate Editor granted it. This is normal practice at Analytical Chemistry.

What you should NOT do during the first 5 to 8 weeks is email the editorial office. An inquiry at 5 weeks adds friction without accelerating the timeline.

If your Analytical Chemistry paper is rejected after review, the natural cascade depends on what the reviewers and Associate Editor cited:

ACS Measurement Science Au is the natural ACS open-access cascade for measurement science papers.

ACS Sensors is the ACS cascade for sensors specialty papers.

Analytical and Bioanalytical Chemistry (Springer) is the external Springer cascade for bioanalytical chemistry.

Talanta (Elsevier) is the external Elsevier analytical chemistry cascade. Talanta uses Editorial Manager at Editorial Manager submission portal; editorial contact talanta@elsevier.com.

JACS is the broader ACS chemistry flagship. JACS uses ACS Paragon Plus at ACS journal page; editorial contact jacs@acs.org.

Lab on a Chip (RSC) is the external RSC microfluidics cascade.

The author guidelines say reviewers evaluate manuscripts on originality, technical quality, clarity of presentation, and importance to the field. The table below translates that into four preparation areas for analytical-method papers.

In our pre-submission work with Analytical Chemistry-targeted manuscripts, three named patterns generate the most consistent reviewer concerns and the most common reasons papers miss the editorial bar or fail the desk screen.

Incremental method modification flagged at Associate Editor desk screen. When the work presents incremental modifications to existing methods without clear method-development novelty, Analytical Chemistry Associate Editor desk rejection is common. The strongest manuscripts frame genuine method-development novelty in the abstract, method-comparison table, first figure, validation workflow, and limitations paragraph.

Method validation gaps surface as reviewer concerns. When method validation parameters (LOD, LOQ, calibration linearity, recovery, precision, matrix effects, robustness, and reproducibility) are incomplete or inadequately characterized, reviewers consistently request additional validation. The strongest revisions include full method validation in Supporting Information and make each performance claim traceable to a table, raw-data repository, or protocol.

ACS family cascade offers from Associate Editor. When the Associate Editor concludes the work is rigorous but the analytical chemistry bar of Analytical Chemistry is not met, transfer offers to ACS Sensors (sensors specialty), ACS Measurement Science Au (open-access), or JACS (broader chemistry) are common. ACS editors take these transfers seriously, and the decision letter often tells authors whether the issue is method novelty, application fit, validation depth, or journal routing.

We have reviewed 50+ manuscripts targeting Analytical Chemistry, ACS Sensors, ACS Measurement Science Au, JACS, Talanta, and Lab on a Chip. This guide tells you what Analytical Chemistry editors look for in the status window, while the review tells you whether your paper passes the same method-novelty, validation, characterization, reproducibility, and cascade-fit checks before the Associate Editor or external reviewers see it. Full Manusights reviews include a 60-day money-back guarantee, and we do not train models on your manuscript.

In our pre-submission review work across analytical chemistry, sensors, microfluidics, and measurement-science targets, Analytical Chemistry-bound drafts most often failed when the method claim was plausible but the validation package did not prove it across realistic matrices or reproducible operating conditions. We see this as a recurring failure pattern because Associate Editors can often see whether a paper is a genuine analytical-method advance or a performance report missing validation depth.

Source limitation: official guidance explains ACS submission requirements and reviewer workflow, but it cannot diagnose whether your specific LOD, LOQ, recovery, precision, and matrix-effect package is strong enough for Analytical Chemistry.

This page was created from ACS's public Analytical Chemistry author guidelines at ACS author guidance, ACS journal metrics (median days to a first editorial decision, to a first decision with peer review, and to acceptance), the Editor-in-Chief's December 2025 editorial on prescreening, and the Associate Editor accept/reject/revise model, and Manusights pre-submission review experience with Analytical Chemistry-targeted manuscripts.

For the ACS analytical chemistry landscape beyond Analytical Chemistry, see ACS Measurement Science Au (open-access measurement), ACS Sensors (sensors specialty), JACS (broader chemistry), and external analytical chemistry alternatives (Analytical and Bioanalytical Chemistry, Talanta, Lab on a Chip). The choice across these titles depends on whether the central contribution is top ACS analytical chemistry (Analytical Chemistry), ACS open-access measurement (ACS Measurement Science Au), sensors (ACS Sensors), broader chemistry (JACS), bioanalytical chemistry (Analytical and Bioanalytical Chemistry), Elsevier analytical chemistry (Talanta), or microfluidics (Lab on a Chip).

Reviewers at Analytical Chemistry typically draw from method-development subspecialty experts. Editors screen and triage manuscripts before any reviewer sees them, and preparing a response template that addresses both method-development novelty and method-validation rigor accelerates revision rounds substantially.
