What this is: the chain-of-custody header for the tested unit. The accession number ties this certificate to the laboratory’s internal record so any result can be independently re-verified with Freedom Diagnostics.
Purity Analysis
Quantifies how much of the sample is the intended compound versus related impurities.
Purity (HPLC-UV)
99.45%
Area-under-curve at 214 nm
Identity (LC-MS)
GLP RT
Observed mass matches theoretical
Net Peptide Content
23.01 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>.
Result
Cleared
Below detection threshold
Sensitivity
n/a
Assay limit of detection
Method
LAL
Run in duplicate
What this measures: the Limulus Amebocyte Lysate (LAL) assay detects bacterial endotoxin down to the stated sensitivity. “Cleared” means none was detected above the assay’s limit. Tested in duplicate.
