Used STANFORD RESEARCH SYSTEMS / SRS RGA200 #293751915 for sale

STANFORD RESEARCH SYSTEMS / SRS RGA 200 is a residual gas analyzer designed to measure the partial pressure of molecules of interest in an enclosed vacuum chamber. This instrument is used to identify, quantify, and control contaminant gases which can affect the performance of a variety of vacuum systems including electron microscopes, semiconductor fabs, sputter tools, high vacuum systems and other analytical tools. SRS RGA 200 consists of three major components; a mass spectrometer source, a vacuum chamber and a set of electronic controls. The mass spectrometer source is used to generate an ion beam which passes through the sample. The incoming ions are analysed by the mass filter which separates ions by their mass-to-charge ratio, allowing for the identification and quantification of species within the gas sample. Once the ions are analyzed, the output is detected and displayed on a display unit in the form of a mass spectrum. This spectrum can be used to identify specific species in the sample and quantify the relative partial pressure of their individual components. The vacuum chamber is essentially an enclosed system with a vacuum input, a pumping system, and an isolation valve. To analyse the sample, the chamber is first pumped down to the desired level of vacuum, and then the isolation valve opened to allow the sample species to be drawn into the chamber. Once inside the vacuum chamber, the sample is bombarded with high-energy electrons resulting in the ionization of the sample species which will then be subsequently analysed. Finally, STANFORD RESEARCH SYSTEMS RGA 200 also includes a set of networking and controlling hardware, such as a controller board, a sensor module and power supplies. These components are primarily used to control the vacuum pressure inside the chamber as well as the parameters of the electron beam. Additionally, network connectivity allows for integration of various features such as remote control of the instrument. Overall, RGA 200 is an indispensable tool for analysing and quantifying partial pressures of various species in vacuum chambers. The instrument is capable of providing precise data and is easily portable, making it an ideal solution for a variety of applications.
