FAQ
What is Dry Column Chromatography?
Dry
column chromatography (DCC)
is a versatile Prep LC method
Basically, any sample that can be
separated on silica gel or neutral alumina TLC plate can also be
separated by the corresponding DCC-setup. The dry-column procedure
has been successfully applied for the preparation of dye-stuffs,
alkaloids, and other heterocyclic substances which are known to be
separated on other types of columns, but, with
considerable difficulties. Lipids have also been successfully
separated.
Dry column chromatography bridges the gap between analytical
TLC and preparative classical column chromatography. The cost is
much less
than the cost incurred in instrumental pressure associated
with preparative liquid chromatography.

The load sample versus adsorbent is maintained at
approximately less than 1:500 in TLC while the ratio is
1:300 or even higher for dry column chromatography.

The
Dry Column Technique
Bridges the gap between preparation
column chromatography and analytical thin-layer chromatography.
Dry Column
Chromatography
This is a unique
and simple method for purifying material. If inexpensive and fast. It
is single column elution technique. Below is a schematic form of the
method.
