Lot V260730-6 — ARA-290 16mg — third-party test record
This page is the permanent record for one lot of material: what was tested, by which laboratory, under which method, and what the report says. The report images below are the source documents.

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.
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.
Residual solvents
A gas-chromatography run screens for solvents left over from synthesis and lyophilisation, each reported in parts per million against its own limit.
Acetonitrile and trifluoroacetic acid (TFA) are the two rows most often asked about on a peptide lot.
