Pfeiffer Vacuum introduces new gas analysers

Pfeiffer Vacuum has introduced the OmniStar and ThermoStar GSD 350 compact, portable benchtop gas analysers for use at atmospheric pressure. The gas inlet is fitted with a heated capillary for use at up to 350 °C. This prevents vapours from condensing during process gas analysis. Thanks to the two-stage inlet system, an almost segregation-free gas supply is possible. The ThermoStar solution was specially developed for coupling with thermo balances. The inlet system with a quartz capillary and a platinum orifice ensures that even the smallest concentrations can be analysed. The OmniStar was developed for a wide range of applications and uses a stainless steel capillary as well as a valve which can interrupt the sample gas stream. Unlike other analytical methods, the two new devices allow simultaneous detection of all gases within the mass range.

The new PV MassSpec software enables qualitative and quantitative analyses. This software offers a clear and user-friendly platform for recording and displaying measurement data and parameter settings, and complete measuring procedures can be programmed and automated. With a range of instruments available, the mass ranges of 1–100 u, 1–200 u and 1–300 u are covered.

The new instruments have low detection limit (depending on the mass range) of up to <100 ppb, gas consumption of 1–2 sccm and fast measuring time (up to 1 ms u–1). For extended process customisation, an integrated mass calibration device or a controlled purge gas system for corrosive gases are available.
