The Hiden HPR-XX series of gas analysers represents a suite of mass spectrometer-based systems each refined for specific applications accommodating sample pressures ranging from high vacuum to 30 bar. All systems share a comprehensive control program featuring fast analysis rates, multichannel monitoring and 10-decade dynamic range together with integrated statistical data presentation. Mass range options extend from 200 amu for routine species to 2500 amu for specialised applications.

Each integrated system and gas handling interface is optimised for the specific user process addressing diverse applications including gas composition and purity measurement, thermogravimetric and catalysis studies, dissolved species monitoring, the philosophy exemplified by the new addition to the range - the Hiden HPR-90 - featuring a unique multistream selector valve with 40 or 80 sampling lines designed specifically for atmospheric monitoring and reactor vessel environment/ top gas analysis.
