Video demonstrates the advantages of the Brooks Granville-Phillips Vacuum Quality Monitor (VQM) at Ultra High Vacuum (UHV) levels vs. an SRS Quadrupole Residual Gas Analyzer (RGA). The mass spectrometry results are compared in addition to the contribution each instrument makes to the vacuum environment. Resolution and the ability to detect fast transients is also shown.
This video demonstrates how to perform a simple vacuum chamber Helium leak detect using the 835 VQM mass spectrometer. In addition, a technique to increase sensitivity, allowing the detecting of small leaks, is shown.
Granville-Phillips Vacuum Quality Monitor product overview. By using an entirely new technology for mass spectrometers, the VQM offers many advantages over traditional quadrupole Residual Gas Analyzers including Speed, Size and Ease of Use. Included are a description of the technology, comparison to quadrupole RGAs, and a software demo.
