Applications and Capabilities
The ABRF’s GC-MS is a Thermo Scientific Trace GC Ultra-DSQ II system. The DSQ II mass spectrometer features a dual-stage, single-quadrupole design. This instrument is a latest generation GC-MS and was installed in late 2006. It is fitted with a dual-capability ionisation source that can operate in Electron Impact (EI) or Chemical Ionisation (CI) modes. EI is the most common ionisation mode used for GC-MS applications. The mass range of the DSQ II is 1 to 1050u. Additionally, this system is equipped with a liquids and headspace autosampler. Searching against mass spectral libraries (databases) for compound identification and/or confirmation is possible using the installed libraries (NIST 2008, NIST RI, Wiley 8th, Fiehn Metabolomics, Max Planck GOLM, and many others).
