WARRINGTON, UK, March 15, 2010 – Hiden Analytical Ltd.’s Transient mass spectrometer system is designed for the analysis of fast transient gas events at pressures near atmosphere. The compact benchtop system is based on the proprietary HPR-20 QIC series gas analyzers and features a fast response capillary inlet and the HAL/3F PIC mass spectrometer with a pulse ion-counting detector. The combination enables inlet system response times of <150 ms and measurement speeds of up to 500 data points/s over a seven-decade dynamic range. The system monitors species with molecular weights to 300 atomic mass units, with higher mass ranges available. The MASsoft control and data acquisition software provides integral calibration routines and user-programmable template files for automatic analysis. Multiple input/outputs permit integration of external parameters such as temperature or flow rates, and control of external equipment with species-specific pressure level sensors. Applications include pulsed gas experiments for catalyst characterization, surface reaction and reduction studies, respiratory analysis and process control.
