Purity Analysis
Quantifies how much of the sample is the intended compound versus related impurities.
Purity (HPLC-UV)
99.8%
Area-under-curve at 214 nm
Identity (LC-MS)
Selank/Glycine
Observed mass matches theoretical
Net Peptide Content
10.55 mg
Per labeled vial
What this measures: HPLC-UV separates the sample and measures the target peptide’s peak area against impurity peaks — reported as a purity percentage. LC-MS confirms identity by mass. Net peptide content reflects the actual mass of active peptide in the vial.
Endotoxin Analysis
Screens for bacterial endotoxin (lipopolysaccharide) using the LAL method per USP <85>.
