Development of a specific device for densitometry of thin-layer chromatographic sheets in planar chromatography

Abstract A specific device for densitometry of Empore TLC sheets is described and it is compared with two other devices using one or two glass plates as support. This comparison lie on a reading by densitometry at 225, 275 and 520 nm in reflectance and transmittance on silica gel and C 18 sheets. The results of an application to the determination of aspartame are presented.
