ABB VA-MC15-05 Redundant channel card

The mass spectrometer must be calibrated before quantitative analysis can be performed. If this involves recurring processes, such as calibration with subsequent quantitative analysis, these processes can be automated using a scripting language (VSTA = Visual Studio for Applications)*. Since pre-configured modules may be used to do so, an extensive measurement project can be generated quickly.

Gas analysis

Quadrupole mass spectrometers require a working pressure of less than 1 · 10-4 hPa under high vacuum. To analyze gases at higher pressures, as are encountered in many vacuum processes, a perfectly coordinated system is required, consisting of a mass spectrometer, a gas inlet with a separation-free pressure reducing valve, vacuum pumping stations and total pressure measurement. With its quadrupole mass spectrometer-based products, Pfeiffer Vacuum provides the perfect solution for analyzing every gas in the ultra-high vacuum range right up to atmospheric pressure.
