High pressure gas analyzer of the QMS series offers high-quality performance, while still being a cost-effective solution. It efficiently monitors gas leakage, and performs various gas measurements needed for a functional system. It can sample gases at flow rates of a few ml/min. The inlet can operate under pressure ranging from 1 to 10 mbar. The QMS constantly gathers data, unlike the conventional gas chromatographs that analyze batches of gas samples.
