Stanford Research Systems QMS200 High Pressure Gas Analyzer MS Mass Spectrometer offer an efficient, cost-effective solution for a wide range of applications. These mass spectrometers simplify the task of on-line process monitoring, analysis of gas species, leak detection, and troubleshooting.

The QMS system can continuously sample gas at flow rates of several milliliters per minute. The inlet can be equipped to sample at pressures from 1 bar to 10 mbar. Data is acquired continuously, as opposed to batch sampling which is employed by gas chromatographs.
