Unmatched Mass Spec Technology for Real-Time, Multi-Species Monitoring

Our Extrel MAX300-CAT Laboratory Analyzer is a fast, high-sensitivity, quantitative gas analyzer for catalysis, reaction monitoring, and environmental research.  This powerful quadrupole system performs high precision quantitative analysis of every component in a gas or vapor mixture and can be equipped for the fully automated sampling of 61+ gas channels.

With the ability to track concentration changes from ppb levels to 100% and continuous data updates in seconds, the MAX300-CAT provides a compact, flexible platform optimized for gas reaction studies in catalysis, bioreactor control, process development, and environmental analysis. 

The Questor5 quantitative analysis software is easy to use and can instantly calculate derived values from acquired data.  The inclusion of a wide range of communication protocols allows for seamless integration with benchtop reactors, thermal analyzers, or other lab equipment.   The MAX300-CAT joins the ultra-sensitive MAX300-LG benchtop series, and the high-performance VeraSpec APIMS to provide a full range of gas analyzer solutions for laboratory and research applications.

Simply select the gases to measure, or the mass range to scan, in the software and the MAX300-CAT is configured to monitor a new reaction or process.
