Abstract
Improvements in chromatographic column construction, resulting in facilitating packing techniques, and preparation. Use of improved column in analytical and preparative chromatographic applications produces higher efficiencies, lower solvent pressures, faster throughput, and improved resolution of components. Column construction is such, that mechanical energy can be applied longitudinally to the column outer surface, to produce standing waves or controlled vibrations in the packing. The applied energy is in the preferred form of sonic or ultrasonic vibrations.
Claims28
The method of treating packing in a chromatographic tube, the packing adapted to disperse a sample to be analysed, the steps that include:
- (a) vibrating the tube to produce tube oscillating displacement,
- (b) and transmitting said tube displacement to said packing in the tube.
The method of treating packing in a chromatographic tube, the packing adapted to disperse a sample to be analysed, the steps that include
- (a) producing oscillatory displacement, and
- (b) transmitting said displacement into the packing, in the tube.
The method of treating a sample in a chromatographic tube which contains packing to disperse the sample, the steps that include
- (a) producing oscillatory displacement, and
- (b) transmitting said displacement into the sample in the packing, in the tube.
In combination with a chromatographic tube for packing adapted to disperse a sample to be analysed,
- (a) means operatively coupled to the tube for producing tube oscillatory displacement transmitted to said packing.
