Thin-layer chromatography is employed in many areas of QC and routine monitoring of product quality [458]. Fluorescence scanning, densitometry or videodensitometry are used for quantification. Not all polymer additives are amenable to TLC analysis. Some fatty acid amides are virtually insoluble in organic solvents and cannot be isolated by thin-layer or column chromatography. 

A number of compounds have been quantified by tic or high performance thin-layer chromatography (hptlc) using absorption or fluorescence scanning densitometry. 

From a review of the available literature it is clear that methods based on thin layer chromatography are frequently being used by various workers in the field for the quantitation of pesticides. In the present paper the quantitative TLC technique using densitometry is described in detail for the determination of pesticides in various tissues pertaining to actual cases of poisoning. 

Argekar and Sawant [55] developed simultaneous determination of paracetamol and mefenamic acid in tablets by high performance thin layer chromatography method (HPTLQ. The procedure was performed on silica gel using toluene-acetone-methanol (8 1 1) as the solvent system. Detection and quantification of the substance was assayed by densitometry at 263 nm. The linearity ranges were 120-360 ng/pL and the RSD were between 0.41 and 0.78%. Limit of detection and limit of quantification were found to be 1.80 and 5.5 ng/pL, respectively. Recoveries were in the range of 95.50-103.60%.
