The expression Compact Mass Spectrometer (CMS) addresses the need of organic and synthetic chemists to understand the optimal time to quench a reaction mixture. They can obtain answers within minutes rather than hours or days. Additionally, the multiple inlet techniques of the atmospheric samples analysis probe (ASAP)Plate Express TLC plate readerdirect injection and more provides the ultimate in flexibility for sample analysis without the need for complex sample preparation.

The expression family of compact mass spectrometers was developed with maximum versatility in mind and is also the ideal detector for flow injection/direct syringe injection, flow chemistry reaction monitoring, flash chromatography, preparative liquid chromatography, and supercritical-fluid chromatography.
