Testing & Methods

Receipts included.

Every listed batch is meant to travel with accessible analytical documentation. This page explains — at a general level — how identity and purity are assessed, and what a certificate actually shows.

Purity is reported with its method. For laboratory research use only.

Analytical methods

Two questions, answered separately.

"Is it the right molecule?" and "how pure is it?" are different questions, so they get different instruments. Here is the general idea behind each — descriptive only, not a lab protocol.

RP-HPLC

Purity, by separation

Reversed-phase high-performance liquid chromatography pushes a dissolved sample through a column that separates its components by how they interact with the column material. Different substances emerge at different times, producing a chromatogram of peaks.

  • The main peak represents the target compound; smaller peaks are related substances.
  • Purity is reported as the target peak's share of the total — a single, specific percentage.
  • One number never tells the whole story, which is why the method is stated alongside it.
LC-MS

Identity, by mass

Liquid chromatography-mass spectrometry combines a separation step with a detector that measures the mass-to-charge ratio of a compound's ions. The measured mass is compared against the expected value for the target molecule.

  • A match between measured and expected mass supports the compound's identity.
  • Identity confirmation is what lets a material carry a specific label.
  • Identity and purity are reported independently — one does not stand in for the other.

Method descriptions are general educational summaries, not laboratory procedures or specifications.

Sample certificate

A certificate, demonstrated.

This is what a certificate of analysis looks like: clear identity, a measured purity result, and the method behind the number. The values shown here are demonstration data for layout only.

Demonstration data — not a real test result. For laboratory research use only.
