GC-Triple Quadrupole Mass Spectrometer (GC-MS/MS)

Description

This platform is dedicated to the highly sensitive, quantitative, and targeted analysis of small molecules The standard set-up is used to analyse non-volatile compounds (mostly primary metabolites). The system is equipped with a sample preparation robot that is capable of automated online TMS derivatisation procedure especially suited for non-volatile compounds including amino acids, organic acids, mono- and disaccharides.

The analyses is done by a technique called multi reaction monitoring (MRM), where only specific target mass ions are selected by the first quadrupole and subsequently fragmented by the second quadrupole, to obtain a set of “daughter” mass ions. These “daughter” mass ions are highly specific for a particular analyte of interest. The third quadrupole is then used as a scanning device or mass filter. This allows a very sensitive detection of analytes even in complex sample matrices with a high dynamic range. 
Next to the MRM analysis of target compounds the system can be run in full scan mode, simultaneously enabling the untargeted analysis of target and non-target compounds, including spectral matching of unknowns with mass spectral libraries (e.g., NIST 14).

Technical Details

The system comprises a Thermo Scientific GC-MS/MS consisting of a Trace 1300 GC with a PTV injection unit. The GC is equipped with a Deans heart cutting module to selectively remove unwanted analytes from the chromatogram. The GC is connected to a TSQ8000 Duo triple quadrupole mass spectrometer from Thermo Scientific Instruments. At the forefront a Thermo TriPlus RSH autosampling robot is installed.
