Abstract

The use of Supersonic gas chromatography-mass spectrometry (GC-MS) in achieving extension of the range of compounds amenable for GC-MS analysis was discussed. It was based on the coupling of Supersonic molecular beam (SMB) inlet and ion sources with a bench top Agilent 6890 GC + 5972 MSD with the addition of a 520 l/min rotary pump and 60 l/sec air cooled diffusion pump. It was shown that the Supersonic GC-MS enables fast splitless injection and analysis with column flow rate over 130 ml/min He. It was found that the GC elution temperature can be significantly lowered upon the reduction of the column length, increase of carrier gas flow rate, reduction of capillary column adsorption film thickness and lowering the temperature programming rate.
