Unlisted compound — custom analysis

Not on the menu? Send it and we will identify what we can and measure what we can.

Our capability goes beyond the catalogue. If the compound is not listed, send it: we attempt identification by mass, and report content where a reference standard exists. If we cannot test it, we tell you before you pay.

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.
