What this test tells you

Identity — LC-MS

Confirms the molecule is what the label claims, by measuring the mass of the eluting ions. Catches substitution and the wrong compound entirely.

Content — quantitative HPLC

How much is actually in the vial, compared against the declared strength and reported as a percentage of claim.

Purity — HPLC-UV

Area percent of the main peak, with the chromatogram attached so the figure can be checked rather than trusted.

A verifiable report

A report ID and unique key that resolve to a public record. Anything that does not resolve is not a genuine report.

Parameters

No fixed parameter sheet for this test. The method depends on the sample we receive. Contact us and we will tell you exactly what will be measured before you send anything.
