Conclusions

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.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
