TEXT: The possibility has been examined of performing chromatography
as a continuous process. This would be extremely favorable for the
large-scale partition of mixtures. The simplest solution of this problem
seems to be the creation of apparatus on the basis of extraction
columns, i.e., with a counterflow of ionite powder and solution. To pre-
vent the longitudinal intermixing of the liquid, which would be inevit-
able in this case and would impair the creation of the highest possible
number of partition stepap it is suggested here that the counterflow of
the solid sorbent be replaced by a oounterflow of the vessels filled with
the solid sorbent. The suitability of such a solution was proved by
Spedding Powell, and Svec (Ref.1). A system with a counterflow of the
vessels 4ig.1) consists of a set of columns with ionite. The zone of

the mixture to be separated is situated in one of these columns. Under
the action of the displacing ionic current, the mixture zone is shifted
into the next section) from this again into the next, etc. If the dis-
placing and-the ions are properly selected, it can be shifted as far as
desired, without thereby losing their size ~or shape. The mixture compo-
nents, in this connection, concentrate at both ends of the zone. Once
the equilibrium distribution of the components is stabilized, the perio-
dic taking of partition products is started. This takes place at the
moment when the mixture zone changes over from one section into the
other. The problem of the distribution of mixture c6mponents was solved
for the case of a stationary zone by S. Yes Brealer (Ref.2). An ana-
lysis was made of the operation of a chromatographic partition system
