- W2497484382 abstract "Thin-layer chromatography is well established as a clean-up technique for environmental samples and it has been used successfully for many years to separate pesticide residues from interfering co-extractives. In the late sixties instrumentation for measuring the absorbance, transmission and reflectance of compounds separated as spots on thin-layer chromatograms (tlc) was developed but detection limits were not very good and reproducibility was a deterrent. Then fluorometers and spectrofluorometers having better sensitivity and selectivity became available for measuring the fluorescence of organic compounds on tlc. At the time gas liquid chromatography (glc) was rapidly becoming accepted as a selective analytical technique for the quantitative determination of pesticides but there were some drawbacks. Many pesticides were thermally unstable or non-volatile which made their quantitative determination very difficult. There was also the need for alternative methods to glc for confirmation purposes. This incited many scientists to develop fluorometric methods suitable for direct quantitative measurements" @default.
