Quality & testing
Quality, proven per lot.
Lots are tested by an independent laboratory, and the results are published by lot number. A catalog page can claim anything; a certificate names the lot, the method and the result.

01IdentityMass spectrometry compares the measured mass with the mass expected for the compound named on the label.
02ContentHPLC quantitation reports how much of the compound the vial holds, in milligrams.
03PurityReverse-phase HPLC reports the share of the detected signal that is the compound itself, for that lot.
04EndotoxinThe bacterial endotoxin result for the lot, reported against the laboratory's stated limit.
