Mass Spectrometers Designed for Liquid, Solid and Vapor Samples

by Jul 31, 2018Analytical

Your research, in your lab, on your time – these are all essential components for a mass spectrometer in the modern chemistry lab. In an industry where waiting for a central lab to provide answers is often times not an option, the growth of benchtop Compact Mass Spectrometers (CMS) has grown to suit the needs of those across the globe. That’s where Advion’s expression® CMS systems come in.

With a wide range of sample techniques to fit a variety of applications, expression® CMS saves time and maximizes progress in the lab while seamlessly integrating LC/CMS with their AVANT Series for liquid chromatography.

Advion’s AVANT HPLC and UHPLC modular chromatography systems are the latest in chromatography solutions. The AVANT series can be customized and configured with a wide range of options to provide flexible LC-MS to meet your needs, from the simplest manual injection HPLC to a fully automated, streamlined UHPLC system and everything in-between. The expression CMS can also integrate with over 250 LC systems from other vendors if you want to interface to a pre-existing LC system.

Presenting Touch Express© Open Port Sampling Interface (OPSI)

Direct analysis of solids, liquids, surfaces and fibers with the expression® CMS

The novel ambient sampling technique was developed by Gary Van Berkel and Vilmos Kertesz, of Oak Ridge National Laboratory. Paired with the electrospray ion source of the expression® Compact Mass Spectrometer, the product incorporates a low volume, open port of continuously swept solvent, flowing directly into the electrospray ion source of the mass spectrometer.

Unrivalled Utility and Flexibility

The expression® family of compact mass spectrometers was developed with maximum versatility in mind. They allow users to switch rapidly between the many different sample introduction techniques required throughout the chemist’s workflow; from simple direct probe analysis to ultra-high performance liquid chromatography and prep-scale purification.

The Industry’s Broadest Range of Innovative Sampling Techniques

Advion provides an extensive range of innovative sample introduction systems that are fully integrated with the expression® CMS to provide solutions for all the chemist’s needs. From the simplest, fastest direct probe analysis requiring no sample preparation to ultra-high performance compound separation with state-of-the-art liquid chromatography systems.



With over 25 years of mass spectrometry and chemistry expertise, Advion has produced a CMS family designed for the chemist. The affordability, small size and ease-of-use makes them ideal for use directly at the bench, giving immediate answers and informed decisions instead of waiting in line at a central analytical service laboratory. Now you can have a mass spec that works the same hours you do.

“expression® CMS meets our requirements for an instrument that is intuitive to use, robust and capable of being maintained, expanded and serviced without manufacturer call outs”
