The Thermo Scientific™ Prima BT Mass Spectrometer is an industrial laboratory gas analyser based on scanning magnetic sector mass spectrometry. Designed for continuous operation in a process environment, the Prima BT mass spectrometer is simple to operate and easy to maintain.
Setup for DEMS (differential electrochemical mass spectrometry) to monitor gas phase products generated during electrochemical processes
Possible to modify flow cell design for alternative purposes (heterogeneous catalysis, dissolved species monitoring, gas separation studies) – Please contact for more information.
