FIELD: physics. ^ SUBSTANCE: column packing method uses an automatic control unit which has software and hardware for automatic operation. The method also involve use of a column which has a movable adapter. The movable adapter can move by pumping liquid into or from the sealed space between the adapter and the cover of the column. The method also involves use the control unit to track movement of the movable adapter in the column. The control unit is programmed to fill the column with working material of a sorbent layer in accordance with current parametres of the working material. Current parametres pertain to given height of the packing layer, volume of suspension with given particle concentration, rate of descent of the adapter and the required degree of compression of the sorbent. The disclosed method also uses the control unit to determine the control point where the movable adapter starts compressing the said deposited layer by calculating the position where pressure starts to increase in the said sealed space. ^ EFFECT: design of a column packing system and a method of packing working material in which a sorbent layer with an optimum compression index is obtained, as well as possibility of reproducible and controlled filling of chromatographic columns. ^ 8 cl, 2 dwg |
