Methodology

Chromatography, spectroscopy, and third-party validation

Raw materials are assessed using chromatographic separation and spectroscopic analysis to confirm identity and profile composition against documented reference parameters. Each catalog batch is reviewed through a structured documentation process before listing.

Third-party validation results are recorded per batch and made available to members on request, so that analytical records remain traceable from intake to catalog.
