Brief Communications


A method for preconcentration of poorly volatile impurities by continuous thermodesorption of the major component on a TLC plate is proposed. The method provides multiple (200–500) concentration of the organic impurities present in the initial solution. A simple device for such concentration is suggested.

Key words
