Abstract
There is disclosed apparatus for rapidly transferring samples for analysis by thin layer chromatography from a sample container to the chromatography plate and in which a chromatography plate is supported in a housing through which drying air, preferably heated, passes over the working surface of the chromatography plate. A plurality of sample applicators are precisely positioned above the plate by means of a transverse mounting plate having a transverse array of holes through which the applicators are passed to engage the working surface of the plate, the applicators taking the form of an imperforate sleeve surrounding a porous core projecting from the end of the sleeve and sharpened to a point to minimize exposure, with the other end of the sleeve projecting beyond the inner end of the porous core to define a solvent reservoir which if desired can be packed with fiber wadding to control fluid flow and with the reservoir adapted to be closed by a sealing cover member.
