Hiden system analyses fast transient gas events

Hiden Analytical has introduced its Transient MS system for the analysis of fast transient gas events at pressures near atmosphere.

The compact, bench-top system is founded on the Hiden HPR-20 QIC series gas analysers and features a purpose-designed fast-response capillary inlet and the HAL/3F PIC mass spectrometer with pulse ion counting detector.

The combination enables inlet system response times of less the 150msec, with measurement speeds of up to 500 data points/sec over an entire seven-decade dynamic range.

The system monitors species with molecular weights to 300amu, with higher mass ranges available for specialist applications.

The Massoft control and data-acquisition programme provides ease of operation with integral calibration routines, together with user-programmable template files for automatic operation of routine analyses.

Multiple I/Os permit integration of external parameters such as temperature or flow rates and control of external equipment with species-specific pressure-level sensors.

Application areas include pulsed gas experiments for catalyst characterisation, surface reaction and reduction studies, respiratory analysis, process control and - with high-speed rotating multiport valve - spacial gas-distribution measurement as demonstrated in the Hiden Spaci-MS system.
