Abstract

This paper considers some aspects of a new TLC technique using a molten mobile phase which is solid under ambient conditions. The flow of high‐boiling mobile phase at elevated temperature in thin‐layer chromatography has been investigated and it is shown that the equation Z~f~^2^ = kt is not applicable to migration of the high boiling mobile phase front. The flow stability of the high‐boiling mobile phase is noted. It is suggested on the basis of studies of concentration profiles of the solidified mobile phases by scanning photometers that the shape of the mobile phase concentration profile be taken into account in calculation of R~f~ Values.
