The coupling of chromatography with MS is a well developed chemical analysis strategy dating back from the 1950s. (GC)–MS was originally introduced in 1952, when A. T. James and A. J. P. Martin were trying to develop tandem separation – mass analysis techniques. In GC, the analytes are eluted from the separation column as a gas and the connection with electron ionization () or chemical ionization () ion sources in the MS system was a technically simpler challenge.
