Chromatography methods and chromatography apparatus |
| 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. |
