Public COA Database

Every COA we issue,
independently verifiable.

Every Certificate of Analysis we issue carries a unique accession number. Public COAs are searchable below — no login required. For COAs the client chose to keep private, paste the accession plus the one-time verification key from your portal.

PUBLIC + KEY-VERIFIED COA LOOKUP

Accession number

Your accession number appears at the top of your COA document.

Verification key (optional, for private COAs)

01 · How verification works

Three steps. Zero login.

STEP 01

Locate your accession number

Find the unique accession number printed at the top of your COA document (format GSA-2026-NNNNNN).

STEP 02

Enter & search

Type the number into the search box. Optionally include the verification key for private COAs.

STEP 03

View verified results

See the original, tamper-proof test result as issued by our laboratory — with the analyst signature and instrument logs intact.

02 · Why verification matters

The receipt has to be the receipt.

Forged COAs are a known industry problem. Our public lookup is the canonical authentication mechanism — if a number doesn't resolve here, it isn't one of ours.

ISO 17025 Aligned

Operated to ISO 17025 expectations across method scope, calibration, and data integrity.

GLP-style data integrity

OECD/FDA-style documentation, retention, and audit-trail discipline. Not a registered 21 CFR Part 58 GLP test facility.

Method-appropriate verification

HPLC + MS standard on every product panel; EPA-reference methods for environmental matrices.

Tamper-proof

Every report verifiable & cryptographically signed.
