Services
Service 01
Standard Mass & Purity Analysis
HPLC-UV purity and mass determination. Fast, validated, priced per peptide.
Price per Peptide
Prices vary because different peptides require different reference standards. The analysis is identical.

Service 02
FlagshipAdvanced Peptide LCMS Analysis
Everything in Standard, plus full mass spectrometry: impurity identification, contamination detection, MS purity, and molecular identity confirmation.
Standard Mass & Purity Analysis
Included — HPLC-UV purity and mass determination.
LCMS Impurities — Identity & Quantity
Each impurity identified by exact mass shift and quantified. You see what they are, not just that they exist.
Contamination Detection
Screens for common synthesis residuals and high-concern adulterants.
MS Purity
UV purity and MS purity compared side-by-side. Both reported.
MS Identity — Molecular Confirmation
Molecular identity confirmed by high-resolution mass spectrometry. Result in ppm vs. theoretical mass.
Extras
Service 03
Endotoxin Testing (LAL)
Quantitative bacterial endotoxin testing by chromogenic LAL assay. Result in EU per vial, within the assay range you choose.
Assay range
