摘要
Chromatographic apparatus has column to receive a chromatography bed and fluid between its two ends. It also has a piston that slides inside the column, at least one probe to detect the surface of the bed at the end of the column containing the fluid, and a regulator for the position of the piston according to the detected surface of the bed. Chromatographic apparatus has column (12) to receive a chromatography bed and fluid between its two ends (16a, 16b), with the layer (48) of fluid being set by the surface of the bed and one end (16a) of the column. It also has a piston (36) that slides inside the column, at least one probe (45, 46) to detect the surface of the bed at the end of the column containing the fluid, and a regulator (52) for the position of the piston according to the detected surface of the bed.
