Introduction

Thin-layer chromatography (TLC) and high performance thin-layer chromatography (HPTLC), collectively often referred to as planar chromatography, in combination with in situ mass spectrometry (MS), provides a reliable means for the unequivocal identification of substances separated by this type of chromatography. More specifically, the ability to obtain mass spectrometric information from the separated analytes directly from the TLC/HPTLC sorbent obviates the need to recover the analytes of interest prior to analysis. Although TLC-MS is a useful method of separation and detection, it does have its limitations where complex matrices are encountered. However, tandem mass spectrometric (MS-MS) techniques can be used to enhance the mass spectral data by reducing the interference caused by coeluting analytes or general background noise generated by excipients on the plate.

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.
