  • Method and apparatus for multiple development of thin-layer chromatography plates
    Patent number: 4125464
    Abstract: Method and apparatus for the automatic multiple development of thin-layer chromatography plates. Instead of drying the plates by irradiation a laminar stream of inert gas is passed over the plate. Substances, which decompose at higher temperature, may be treated by chromatography, whereby reproducibility and sensitivity are higher and the productivity is increased.
