KPV Vial 10 mg lot KPV10-004 test results, explained

Every result printed on this certificate, as reported by Freedom Diagnostics, with a plain-English note on what the test measures. "Pass" and "specification" wording comes from the certificate; where the lab prints no pass/fail, we say so.

TestResult on the certificateWhat it measuresThis lot
HPLC purity99.695%HPLC separates the sample into its components; purity is the share of the detected signal that sits in the main peak. On its own it doesn't show which molecule that peak is. That's what the identity test is for.No pass/fail printed; reported value at or above 98%
Identity (LC-MS)Mass identified as KPV · compound named: KPV · mass identification table: KPV: 99.695%Mass spectrometry measures the molecular mass of what's in the vial and compares it with the declared compound. "Confirmed" means the lab found the expected compound. Expected average molecular weight of KPV (PubChem): 342.43 g/mol. The observed mass appears in the certificate's chart and isn't transcribed here.Reported as matching the declared compound
AppearanceWhite Lyophylized PowderWhat the lab recorded before testing: the colour and physical form of the material.Recorded
