FTIR Evaluation of Planar Chromatograms

The combination of planar chromatography with Fourier transform infrared in situ evaluation is a useful method for the identification of complex mixtures and their constituents. Although determination limits (1-10 |g per fraction) are higher than those for in situ UV spectroscopy, the method can be used for the quantification of substances that exhibit no suitable UV response and are not amenable to derivatization. A major drawback of in situ FTIR is the strong absorption of silica gel between 3700-3100 and 1650-800 cm-1. Spectral correction can be achieved by background subtraction of data recorded from an empty track.

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.
