Methodology

How We Test

Every certificate of analysis includes data from multiple complementary analytical methods.

HPLC Analysis

High-performance liquid chromatography determines purity and detects impurities. Full chromatograms are included in every COA.

Mass Spectrometry

ESI-MS confirms molecular identity by verifying expected molecular weight. Spectral data is documented in the COA.

Third-Party Verified

Independent laboratory verification provides unbiased confirmation of purity, identity, and absence of contaminants.
