[Simplification of combined thin-layer chromatography/infra-red spectroscopy using Silufol plates].
A simplified method for combining thin layer chromatography and infrared spectroscopy was developed. It concentrated compounds in separation just on the treated original chromatogram (after a special cutting out zones). Reduced number of operations substantially decreased losses of studied substances. Minimal amount of a substance for producing the spectrum was about 30 micrograms.
