unique feature of PC is the possibility of using the layer for storage. For quantitation
in MD-PC, it is our opinion that we are close to the time when slit-scanning densito-
metry will be replaced by quantitative image analysers.
On the basis of theory and experimental observations it can be predicted that a
zone capacity of ca. 1500 could be achieved by 2-D multiple development. Because
the same result can be achieved by application of 2-D forced-flow development on
HPTLC plates, it can be stated that the combination of stationary phases, FFPC and
n
D offers a fruitful future in modern, instrumental planar chromatography.
