MS – Pfeiffer Omnistar GSD 320

The Pfeiffer Omnistar GSD 320 mass spectrometer (MS) is a bench-top instrument for detecting 1-200 amu. The detection limit is <1 ppm for the C-SEM detector and <40 ppm for the Faraday cup. It is controlled by the software Quadrera. The MS and the Discovery TG can be started at the same time by a trigger. The MS data can be collected in two basic ways; either all 200 amu channels are scanned consecutively for a period of time, to find signals of interest, or a selected number of channels are scanned, giving a higher sensitivity for each channel.
