ABSTRACT:
Ultrasound transceivers (20) are distributed up the side wall of a chromatography column (1) and enable tracking of the progress of a rising bed front (5) during packing. Comparison with a predetermined stored profile is used for feedback control of the packing pump P. Other uses of ultrasound monitoring of the column interior are disclosed.
