The approach to analysis by TLC/HPTLC-MS may be divided into two basic methods: instrumental and manual. The instrumental method involves the use of an automated probe onto which the whole chromato-gram is attached. With this method, the integrity of the chromatogram is retained, but is restricted to ionization in the liquid phase by methods such as FAB and the related technique of liquid secondary ion mass spectrometry (LSIMS).

The manual technique involves the removal of the zone of interest from the plate. After removal, the analyte may be extracted from the sorbent prior to analysis, or analysed directly from the sorbent. The manual method is readily implemented and requires no further equipment or interfaces. Also, the classical vapour-phase electron and chemical methods of ion-ization (EI/CI) can be used.
