The use of MS and MS-MS as methods of detection in TLC and HPTLC separations is now well established and has been shown to be a powerful tool in the analyst's armoury. In practice, HPTLC-MS-MS has been shown to be no more technically demanding than traditional TLC-MS, yet the information provided is more detailed. Structurally important diagnostic ions are more easily observed by the elimination of matrix ions and general background clutter. Planar separation should be considered as a complementary technique alongside column methods of chromatographic separation where detection is by mass spectrometric methods. It can be applied to a wide range of polar and nonpolar analytes and is amenable to vapour-phase and liquid-phase methods of ionization. Moreover, where ionization is by laser desorption, separation by planar techniques may be the only choice.
