The Expression CMS Compact Mass Spectrometer from Advion

With more than 25 years of mass spectrometry and chemistry expertise, Advion introduces the expression series of compact mass spectrometers. The small size, affordability, and ease-of-use make them perfect for direct use at the bench, giving instant answers and informed decisions rather than waiting in line at a central analytical service laboratory.

Only a few laboratories examine one type of sample or one method all the time. The majority of other labs require the ability to examine a range of samples using more than one method. This enables a more complete sample identification and characterization. The expression CMS fits in with almost every chemistry method from the simplest, fastest direct probe analysis requiring no sample preparation to ultra-high performance compound separation with LC integration. The expression CMS delivers the most versatile sample methods on the market, including:

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

Developed with highest versatility in mind, the expression CMS allows users to switch quickly between different sample introduction methods with little sample preparation, making it suitable for a range of applications:

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


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

  • CheMS
  • Data Express
  • Quant Express
  • Mass Express
  • Peak Express™
  • LC Express
