Gas Chromatography High Resolution Mass Spectrometry (GC-QTOF MS)

Description

DTU will like to buy a High Resolution (QTOF) gas chromatography (GC) mass spectrophotometer for target and untargeted screening approaches as well as unknown compound identification of challenging food matrices. Lot 1: DTU will like to buy a High Resolution (QTOF) gas chromatography (GC) mass spectrophotometer for target and untargeted screening approaches as well as unknown compound identification of challenging food matrices. Instrument includes a gas chromatograph (GC 8890) equipped with a PAL3 RTC autosampler for sample injection and backflush option for sample introduction to a high resolution mass spectrometer. The GC has one split/splitless inlet and one PTV inlet to introduce larger sample sizes than 1-2 µl. The high resolution mass spectrometer (Resolution) is based on a quadrupole (Q) combined with Time of Flight (TOF) (GC/QTOF 7250) improving the mass accuracy of identified compounds (results of up to four digits), relevant for target and un-target identification. The mass spectrometer is equipped with a low energy capable EI source with ion focusing resulting in the possibility of additional information for identification without having to change ion source. Mass spectrometer includes an oil free fore pump. Instrument control includes a computer with Mass Hunter software, corresponding mass profiler software. Purchase includes relevant mass Libraries as well as installation and 3 days of training. Purchase includes 2 columns, items needed for backflush, a computer for office data analysis, extra ion source and PAL3 RTC Sampler.
