About possibility of videodensitometric registration chromatograms containing liquid mobile phase ON TLC plate
For the first time shown that in principle the possibility of videodensitometry registration final chromatogram of the test mixture on a plate containing a liquid mobile phase, i.e. on "wet" TLC plate without it's drying. A systematic study of videodensitometry changes the basic characteristics of the chromatographic zones of separated compounds over time in terms of volatile mobile phase. Use to detect the chromatogram on "wet" plate TLC videodensitometry method allows, firstly, to increase the recorded signal (20-40%), and secondly, to reduce the duration of the experiment by deleting the stage of drying, as well as to reduce the manual labor in analytical TLC.
