Abstract
To provide a preparative thin layer chromatography method capable of acquiring a target spot efficiently using a simple and convenient method without the possibility of decomposition of a component in a spot. The preparative thin layer chromatography method is a preparative method for dispensing a spot from a thin layer chromatography plate and includes a process 1 that forms a groove by removing the carrier at the circumferential edge of a spot to be dispensed, a process 2 that inserts a nozzle having a packing part at the tip thereof into the groove formed in the process 1, a process 3 that discharges a solvent through the nozzle, and a process 4 that sucks the solvent in which a spot component has been dissolved.
