Mass Spectrometry is probably the fastest growing analytical technique. In the form of Liquid chromatography-tandem mass spectrometry (LC/MS/MS) it provides the preferred method for the efficient and sensitive quantitation of drugs, peptides, and ultimately the widest variety of analytes offered by any analytical technique.  GC-MS is the leading technology for small semi-volatile molecules analysis.

MS often provides very sensitive and specific detection of the analyte of interest. MS-based metabolite profiling represents the dominant analytical mode. MS is taking the place of other technologies in clinical analysis and other application fields.
