Identity, purity, quantitation, endotoxin, and heavy-metal testing for peptides and small molecules — reported on certificates you and your customers can actually trust.
Every sample runs against reference standards with methods referenced to USP <621>, <85>, and <233>. Reports include the chromatogram and mass spectrum, not just a number.
Confirm the compound and quantify chromatographic purity by HPLC-UV-MS with mass-spectral match to standard.
Potency and concentration reported as total mass per vial and percent of label claim.
Monomer vs. aggregate resolution for proteins and larger peptides by size-exclusion HPLC.
Endotoxin quantitation by the LAL method for injectable-intended research material.
Lead, arsenic, cadmium, and mercury screening by ICP-MS against certified standards.
Benzyl alcohol, residual solvents, and preservative content by GC-FID headspace.
A straightforward workflow built for vendors who need results fast without cutting corners.
Send a vial per lot with the batch details. We log it under a unique sample number.
Identity, purity, quantitation, endotoxin, and metals — each on the appropriate instrument.
A signed COA with the chromatogram and mass spectrum, typically within a few business days.
Each certificate ties the result to the physical sample — matching sample number and batch, the actual chromatogram, and the mass-spectral confirmation. Not a template with a number dropped in.
Tell us the compound, the number of lots, and the panel you need. We'll send turnaround and pricing.
