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 Peak Express patented software uses the delta spectrum (∆S) 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
