The reports
What these tests measure
Purity
A purity assay separates the sample on a reversed-phase HPLC column and reports the target peak as a percentage of total peak area.
It answers one analytical question only: how much of the material in the vial is the identified compound, and what else is present.
Heavy metals
Inductively coupled plasma mass spectrometry (ICP-MS) quantifies elemental impurities — typically lead, arsenic, cadmium and mercury — in parts per million or parts per billion.
It is a separate page of the same laboratory report and carries no purity or endotoxin figure of its own.
Endotoxin
A Limulus amebocyte lysate (LAL) assay measures bacterial endotoxin in the sample against the compendial procedure USP <85>, reported in endotoxin units per milligram (EU/mg).
The number is compared to the limit printed on the report; it describes the material, not any use of it.
