Abstract
The simple universal chromatographic chamber with the new contact feeder of a mobile phase of a TLC plate has been proposed; its application for accomplishment of different versions of linear and circular TLC have been demonstrated.
ACKNOWLEDGMENTS
The authors express their gratitude to the reviewers for the comments made.
Notes
tx/ttr–lin is the relation of the duration of separation in the proposed version (descending, horizontal, and ascending mode of development) (tx) to the duration of separation in the traditional linear version (ttr–lin).
is relation of efficiency of separation in the proposed version (descending, horizontal, or ascending mode of development) (
) to the efficiency of separation in traditional linear version (
).
