Thin layer chromatography plates and thin-layer chromatography equipment

摘要

[Problems] The component separation as well improve the analysis efficiency by at high speed, to prevent contamination of the multi-point spot. A surface groove 3a of the substrate 2, 3b, to form 3c, the grooves 3a, 3b, to form the support layer 8 by a coating such as silica gel on the inside of 3c. Moreover, the grooves 3a, 3b, the recess 4a for the inlet end sample spots in the vicinity of the 3c, 4b, 4c form a, in the vicinity of the outlet side end portion of the pair so as to contact the solvent flowing through the flow path electrode 6a, 6b, it provides a 6c as a conductivity detector. The substrate 2 surface can be covered with a lid 10 made of PDMS, the grooves 3a, 3b, 3c and microchannels formed surrounded by the lid 10, the end of the developing solvent which is exposed to the outside suction port 7a, 7b, I and 7c. Thus, since the flow path of each channel is isolated it is possible to prevent contamination and also enables high speed component separation because the capillary phenomenon acts strongly. .BACKGROUND
