Pfeiffer PrismaPro® QMG 250 F3, 1 – 300 u, Compact Mass Spectrometer System, Open Ion Source, Tungsten Filament PTM15311210 / PT M15 3311 210
The Pfeiffer QMG250 PrismaPro® mass spectrometer is designed for partial pressure analysis at pressures < 10-4 mbar. Typical applications are measurement, monitoring and process control functions in vacuum systems.
Quadrupole mass spectrometers with Faraday detectors are the preferred devices for qualitative analysis of the gas composition in a high-vacuum chamber.
Compared with vacuum gauges, quadrupole mass spectrometers offer a much greater wealth of information about the vacuum. A Faraday detector is often sufficient to obtain information about leaks, the release of water vapor or contamination with hydrocarbons under high vacuum. For this purpose, Pfeiffer Vacuum offers a range of quadrupole mass spectrometers with a variety of mass ranges and filament materials.
