Extrel CMS

Real-Time Gas Analyzers for Environmental Compliance, and Combustion Control

Extrel CMS was founded in 1964 as Extranuclear Laboratories by Professors Ted Brackmann and Wade Fite from the University of Pittsburgh. The company was established to provide innovative power supplies for mass spectrometry. In 1985, it became Extrel Corporation to focus more on analytical mass spectrometry products. In 2004, the company changed its name to Extrel CMS, LLC. As of 2025, Extrel CMS is 61 years old. The company has been recognized as a leader in quadrupole mass spectrometry, providing solutions for research, laboratory, and process applications.

Preconfigured, proven EXTREL components can be quickly and easily incorporated into a mass spectrometer tailored to the job at hand. Precision alignment, in-vacuum wiring, and system control can be complex issues.  These analyzers are engineered with function and ease of maintenance.

Each application demands specific capabilities. Our preconfigured, proven components can be quickly and easily incorporated into a customized mass spectrometer tailored to meet the unique requirements of your project.
