COA Decoder

Your COA,
explained.

Add a certificate of analysis (COA) to see what it reports, what is missing, and what to ask the supplier. Get a documentation grade matched to the report’s testing scope, with every check explained.

  • PDFs, scans, and Word files
  • Purity, identity, combined reports, and more
  • Results on this page
  • No account required

Add the report you want to check.

Choose a COA and any supporting documents for one batch. The decoder checks the text for reported results and missing information.

English-language reports · Up to 3 files · 10 MB each · 20 MB combined · 12 pages

Your files stay on your device while the decoder reads them. Use supplier quality documents and remove personal information first.

Optional label cross-check

Copy the material name and batch from the supplied container. The check flags differences from recognized report fields; it cannot authenticate a match. Clear these fields when changing batches.

How Monday grades a document

The grade measures how much required information the text contains. It does not authenticate the report, certify the laboratory, or rate the supplier.

Only the selected testing scopes and shared report details earn points. The score is earned points divided by applicable points, normalized to 100 and rounded to the nearest whole point. Found checks earn full weight; partial references earn half. Tests outside the scope are listed separately and receive no penalty. A: 90–100; B: 75–89; C: 60–74; D: 40–59; F: 0–39. Missing essential evidence or a consistency flag caps the score at 59. Unclear scope, unrelated batches, or unreliable extraction produces no grade. This is documentation coverage, not an analytical pass/fail decision.

A: 90–100 · B: 75–89 · C: 60–74 · D: 40–59 · F: 0–39

  • PurityRelative purity and chromatographic documentation; not the amount in a vial.
  • IdentityReported identification method and observed identity result.
  • Quantity / contentMeasured amount, concentration, or content and its quantitative method.
  • EndotoxinsReported bacterial endotoxin test; separate from sterility.
  • SterilityReported sterility test and conditions; separate from endotoxins.
  • Microbial countsReported microbial enumeration; not a sterility test.
  • Residual solventsNamed solvent measurements and their analytical method.
  • Elemental impuritiesNamed elemental impurity measurements and their analytical method.
  • Water / counterionsReported water or counterion measurements; not peptide content.

Your answers about research resources do not change the documentation grade. Independent and institutional researchers are assessed by the same criteria.
