Used SERVOMEX 244 #73369 for sale

SERVOMEX 244 Residual Gas Analyzer is an analytical instrument designed to measure the composition of residual gases. It allows for real-time analysis of complex gas mixtures by providing components' concentrations (percent volume) in highly accurate and repeatable results. The instrument has a dual-mode operation that enables the user to select either chromatographic or pyrolysis-based analysis. The chromatographic mode of 244 employs the use of two columns, consisting of a short columns of 5% H2 / He or 5% O2 / N2, coupled with a long column of 10% O2/N2/Ar. As the sample passes through the two columns, the compounds are separated and the analytes are identified and quantified based on their individual retention times. The analytes are identified by mass spectrometer and the concentrations of the compounds are then determined by its signal peak areas. The pyrolysis mode of SERVOMEX 244 uses electrical discharge to break down molecular structures of the components and ions are generated from these breakdowns. In this mode, mass spectrometry is used to accurately quantify and identify the composition of the sample gas. The instrument processes the data collected quickly and can provide a detailed chemical profile within a matter of minutes. 244 also has several advanced features to ensure the accuracy of the results, such as a temperature-compensated vacuum system and cell that maintains sample conditions within a range of operating temperatures. Additionally, the instrument has an advanced control system for sample introduction and various software features to analyze and store report data. SERVOMEX 244 Residual Gas Analyzer is a powerful and flexible analytical instrument ideal for a wide range of applications. Its dual-mode operation, advanced features, and rapid data processing capabilities make it an ideal instrument for analyzing contaminant gases and for research purposes. Thanks to 244, researchers and engineers can now accurately and quickly measure the composition of complex gas mixtures in real-time.
