Peak Express® – Unique Mass Spectrometer Software to Look Beyond the Noise and Detect Minor Components and Impurities for the expression® CMS


Introducing a new way to analyze and present mass spectral data, the Advion Interchim Scientific® Peak Express® patented software uses the delta spectrum (ΔS) to quickly and automatically detect significant peaks within mass spectra based on their relative change in intensity over time instead of their absolute intensity.

  • Find impurities and minor components that would otherwise be missed
  • Find unknowns in complex samples such as natural products
  • Automatically find adducts, dimers, fragments, side reactions, and other unexpected compounds in real time and post processing
  • Control mass-directed purification without providing an exact mass
  • Get extracted ion chromatogram (XIC) quality data while scanning the entire mass range
