Design and Implementation of a Gas Generating System for Complex Gas Mixtures and Calibration Gases

摘要

A test gas generation system for complex gas mixtures designed to mimic real industrial gas matrices with traces raging from low pptv to high ppmv level and minor and main components ranging from low to high percentage levels with variable relative humidity levels (0-80 % RH) is presented. It combines different gas generation methods to study fragmentation patterns under controlled conditions by means of a proton transfer reaction time-of-flight mass spectrometer, the application of alternative feedstocks in catalytic processes as well as the performance of gas purification and conditioning processes.
