QC panels / lot
The 7-panel QC on every lot
01
Purity (HPLC)
Reverse-phase HPLC resolves the main peak and quantifies related substances.
02
Net Peptide Content
Labeled-vs-actual mass so you know the vial holds what the label says.
03
Identity (MS)
Mass spectrometry confirms the compound is what it claims to be.
04
HPLC Conformity
Chromatogram shape matches the reference standard.
05
Heavy Metals (ICP-MS)
Screens for trace metal contamination.
06
Sterility
Verifies the lot is free of microbial growth.
07
Endotoxin
LAL assay rules out bacterial endotoxin.
