Mass Spectrometer Uses Digital Detection for Fast Gas Processes
Hiden Analytical has introduced a gas analyser — the HPR-20 QIC TMS system — specifically configured for analysis of fast transient pulses and rapid compositional changes in gaseous processes. Developed for the researcher, the system is suited to studies of diverse thermally triggered and chemically triggered reactions.
The multi-mode Windows MASsoft Professional software features quantitative analysis and statistical data reduction programs, peak area integration and the APSI-MS soft ionisation mode to enhance spectral purity. The system includes provision for import of two external signals to enable simultaneous integration of parameters such as temperature and weight with the mass spectrometer data.
Operating with sample pressures from near-atmospheric up to 30 bar, the benchtop mass spectrometer uses a fast digital detection system for minimised signal response times and features the Hiden triple-stage mass filter for optimum sensitivity, species identification and corrosion resistance. Coupling to the process is via a flexible, heated capillary interface of 0.9 m length with a throughput of just 20 ml per minute.
Measurement rate is up to 500 data points per second over a seven decade dynamic range, with a compositional change at the sample point recorded in less than 150 ms. Pulse profile resolution (5 to 95% peak height) is just 60 ms.
