WebGC-MS can be used to study liquid, gaseous or solid samples. Analysis begins with the gas chromatograph, where the sample is effectively vaporized into the gas phase and … WebThe output on the display should also be very stable at this point—not jumping more than +/- 0.1 pa at a time. If the background stays above 5 pa or is very unstable, suspect the following: 1) The interconnect or spring—loose, contaminated, deformed. (the spring should never be touched with bare hands as this will cause leakage current.)
