WebbSlurry preparation To achieve the correct amount of chromatography resin for packing to target bed height or compression, it is important that you measure slurry concentration correctly. When you prepare the slurry, start by calculating the chromatography resin volume ( V) needed to pack the desired bed height. Webbaxial compression method The parameters extracted from the curves in the open bed measurement are used to set the PF for axial compression for a packing at 30 to 60 cm/h depending on resin PF value for V max pack. If the V max pack is approx. 830cm/h, this corresponds to approx. 1.14 in PF according to Figure 1. This means that your initial ...
WebbNOTES CHROM. 4083 Dynamic packing of ion-exchange chromatographic columns* The conventional method of packing ion-exclhange resin into a chromatographic column is to make a slurry of the resin beads and introduce it into the column or a chamber attached to the column, and then allow the resinl particles to settle by gravity to form the packed bed … WebbFor the wet method, a slurry is prepared of the eluent with the stationary phase powder and then carefully poured into the column. ... the use of this small packing media causes the high back pressure and is why it is termed high pressure liquid chromatography.
