How a sample becomes
a certificate.

Every TB-500 sample moves through the same five steps. No shortcuts for rush orders. No unnamed hands in the middle.

Intake.

Your sample arrives. We photograph it, weigh it, log every detail, and assign a tracking number that follows it onto every page.

Prep.

A named analyst prepares the run: dissolutions, dilutions, internal standards. Their initials go in the log.

Run.

HPLC-UV for purity and LC-MS for identity, with system-suitability standards bracketing your sample on either side.

Review.

A second analyst reviews the chromatogram independently. Nothing ships with one set of eyes on it.

Sign.

The COA is digitally signed, hashed, and published. Anyone with the link can verify the signature against the raw data.

What does the TB-500 Certificate of Analysis include?+
A completed TB-500 COA documents the compound identity (intact mass by LC-MS), the HPLC-UV purity result as percent area, the method parameters used, and the analyst and director who signed off. It is digitally signed and independently verifiable.
How long does TB-500 testing take?+
Typical turnaround is 1-2 days from the day your sample is received at the lab. You'll get shipping instructions, a packing slip, and labels after checkout.
What method is used to confirm TB-500 identity and purity?+
Identity is confirmed by LC-MS intact-mass analysis. Purity is measured by reversed-phase HPLC-UV and reported as percent area.
