  • Device for analyzing substances by means of thin layer chromatography
    Publication number: 20030013187
    Abstract: A device according to the invention for analyzing substances by means of thin layer chromatography comprises a solvent trough (1) with two solvent channels (11, 12). Two wall plates (4, 5) are mounted in the solvent trough (1), enabling thin layer plates (2, 3) to be arranged standing obliquely with respect to the horizontal in the solvent channels (11, 12). The substance to be analyzed can thus be dropped or applied onto the thin layer plates (2, 3) from above, and solvent can be supplied to the solvent channels (11, 12) from above at a solvent supply point (111, 121). The upward migration of components of the substance to be analyzed can thus be started without the position of the thin layer plate (2, 3) needing to be changed for this purpose.
