Thin-layer chromatography environmental analysis

High performance thin-layer chromatography has found its greatest application in the areas of clinical (e.g. analysis of drugs in blood) and environmental analysis.

In this section only the most recent methods (post 1990) for extraction and quantitative determination of PCAs in commercial products and environmental samples are discussed. While extraction and isolation techniques have relied mainly on techniques already developed for POPs, there have been major advances in the quantification of PCAs using gas chromatography mass spectrometry in electron capture negative ionization mode (GC-ECNIMS). No attempt will be made to discuss older methods of analysis such as thin-layer chromatography [13,50], and neutron activation methods [51]. 

The development of different methods of analysis in thin layer chromatography is a very important area of organic chemistry and biochemistry. Analysis of organic acids by thin layer chromatography is widely applied in different fields of environmental, pharmaceutical, industry, industrial foods, organic chemistry, cosmetics, clinical, and biochemical assays.

Currendy, the most important fields of application of thin-layer chromatography are pharmacy (30%), biochemistry, forensic chemistry, and clinical chemistry (25%), environmental (15%), food analysis and cosmetology (10%), inorganic substances (5%), and various other fields (15%). The number of publications in the field of pharmacy steadily increases. 

The currently most important Helds of application of thin-layer chromatography can be seen in Fig. 1. The proportion of publications in the fields of pharmacy and environmental analysis has increased over that in previous years. There has also been an appreciable increase in the fields of cKnical and forensic chemistry and in biochemistry.

Although thin-layer chromatography (TLC) has been found to be useful in the separation of mixtures of organotins, it has mainly been used in quality control contexts to assess organotin purity. However, this method finds applications in water and environmental analysis [96].
