All of our catalog and custom peptides are identified using MALDI mass spectrometry on equipment calibrated using internal and external calibration standards.  We provide mass spec data with each peptide as standard, and all purified peptides come with an analytical HPLC trace if required.

We also offer:

  • Liquid Chromatography-Mass Spectrometry
  • Electrospray mass spectrometry
  • Amino Acid Analysis/ Peptide Content Analysis
  • N – C terminal sequencing
  • Nuclear Magnetic Resonance (NMR) data
  • Stability testing



Our analysis and Quality Control suites are equipped with analytical HPLC systems for determining peptide purity and Matrix Assisted Laser Desorption Ionization Mass Spectrometry (MALDI) for highly accurate determination of peptide identity. It is also equipped with Electrospray Ionization Mass Spectrometry for determination of small peptides and characterization of reagents and Ultraviolet Spectrophotometers as well as other instrumentation.
