Overview.

The Hiden HPR-20 TMS Transient MS is configured for fast event analysis of gases and vapors at pressures near atmosphere. It is ideal for fast gas switching experiments and features the Hiden QIC quartz-lined 0.9 m sampling interface.

The inlet, operating at 200°C, provides response times of less than 150 ms to changes in gas composition, with a 5 decade response time in less than 100 ms.

The QIC inlet is coupled directly to Hiden’s Pulse Ion Counting (PIC) digital MS, which is capable of measurement speeds of up to 1000 data points/s over the entire 7 decade dynamic range. It is suited to fast data acquisition in the measurement of gas and vapor compositions in the sub ppm to low % concentration range.
