Henniker Scientific’s latest version of the MAX300 LG Quadrupole Gas Analyser is now available with an ultra-fast response sample introduction inlet for transient gas analysis applications. The analyser features a fast clearing sample inlet delivering a T90 time response of 85 ms and the ability to report gas concentrations over the range 100% to 10 ppb at a rate of 50 components per second. With a data collection rate for individual points of 80 µs and measurement precision of 0.0025% on a 1% signal, the analyser is suited to rapid response analysis of time-varying evolved gas processes, including pulsed gas studies of catalyst reactions, isotopic transient kinetic analysis and respiratory physiology.
