UCT MCB Triple Quad GC-MS
GC is the preferred technique for the separation of low molecular weight metabolites which are either volatile or can be converted into volatile and thermally stable compounds through chemical derivatization before analysis. This includes primary metabolites, such as amino acids, amines, sugars, organic acids and fatty acids. GC is not the preferred method for secondary metabolites.
The coupling of GC to electron impact ionization (EI) MS is a hybrid technique in analytical chemistry and is considered to be one of the most robust and highly sensitive instrument platforms for metabolite analysis.
MCB’s Triple Quad GC MS is the ideal instrument to be used for compound target analysis.
