Used MKS Vac-Check #179824 for sale

MKS Vac-Check is a residual gas analyzer developed by MKS Instruments, designed to provide fast, reliable and sensitive analysis of gas mixtures in a vacuum chamber. The analyzer works by deploying an advanced Quadrupole Mass Spectrometer (QMS) technique to measure and analyze the pressure, composition and mass of the residual gases. The analyzer is comprised of four main components: a mass spectrometer detector, a pumping system, a source chamber, and a sample chamber. The detector measures the mass-to-charge ratio of the gas particles in the chamber using a quadrupole rod set. This data is then processed by the analyzer's pump, which accelerates the gases against the rod set. The pump increases the pressure differential between the sample chamber and the source chamber, enabling more accurate readings. The source chamber is the primary assembly of the unit, where most of the components are integrated. This chamber has a base plate with a number of components, including the lens array, E-beam source, and Faraday cup for collecting ionized particles. The ionized particles are first accelerated by the E-beam source and are then collected by the Faraday cup. The lens array is responsible for controlling and focusing the energy of the ionized particles to ensure accurate readings. Finally, the sample chamber is used to contain the gas mixture that needs to be analyzed. This chamber also provides the necessary insulation for efficient monitoring of the gases. The sample chamber is connected to the source chamber via a transfer line for easy delivery of the gas mixture to the detector. Vac-Check is an ideal tool for reliable, fast and accurate monitoring of residual gases in vacuum chambers. Thanks to its powerful components, the analyzer makes it possible to precisely measure and analyze the composition, pressure and mass of the gas samples with extreme accuracy.
