Advion, with over 25 years of mass spectrometry and chemistry expertise, provides the expression family of compact mass spectrometers. The small size, affordability, and user-friendliness make them perfect for use directly at the bench, giving direct answers and informed decisions instead of having to wait in line at a central analytical service laboratory.

Only some laboratories examine a single type of sample or one method most of the time. The rest require the ability to examine a variety of samples using more than one method. This enables a more comprehensive identification and characterization of samples. The expression CMS integrates with almost every chemistry method from the simplest, fastest direct probe analysis needing no sample preparation to ultra-high performance compound separation with LC integration. The expression CMS offers the most versatile sample methods on the market, including:

  • Volatile APCI (vAPCI)
  • Inert ASAP (iASAP)
  • Flow Injection
  • Flow Chemistry
  • Flash Chromatography
  • Touch Express™ Open Port Sampling Interface
  • AVANT Customizable (U)HPLC Systems
  • Atmospheric Solids Analysis Probe (ASAP®)
  • Preparative Liquid Chromatography (Prep-LC)
  • Thin-layer Chromatography (TLC by Plate Express™)
  • Supercritical Fluids Chromatography (SFC)

Designed with maximum versatility in mind, the expression CMS allows users to switch swiftly between several sample introduction methods with minimal sample preparation, making it perfect for a range of applications:

  • Clinical Diagnostics
  • Reaction Monitoring
  • Food Safety and Ingredients Analysis
  • Teaching Chemistry
  • Natural Products Analysis
  • Water Purity Determination
  • Proteins and Peptides Synthesis


Advion provides a complete suite of full-feature and easy-to-use software for smooth operation and compound identification.
