Quantitative HPTLC analysis — Industrial applications

Originals

Summary

The use of derivatisation techniques in quantitative HPTLC in situ analysis is shown on the basis of two products that are very different in their manufacture: in situ derivatisations of thioglycolic acid compounds following chromatographic separation and the derivatisation in solution (dansyl method) for thiourea by quantitative in situ photometry are treated for concentrations <1 μg.
