الوصف

Dynamic Axial Compression Column (High Performance Liquid Chromatography Column)

DAC stands for dynamic axial compression. It combines the preparative column and packing system together. It is very simple to operate. The column can be used online when it is packed well. Dont take the column down! Bed compression is maintained constant so that swelling will be prevented. Once particle shrinking takes place because of the solvent flow, the piston will automatically go down to let the bed maintain constant column pressure.

CXTH-PACK DAC can be packed with small particulate media (*0 um less) so as to reach high levels of performance. For columns from *0mm to **0mm internal diameter, the column efficiency can reach up to *0,**0 theoretical plates per meter. This requires an excellent distribution. Our engineers have innovated in the distributing groove at the column ends and designed efficient solvent distribution systems to obtain optimum theoretical plates. For the better control of the chromatographic conditions, DAC columns can be coat with a temperature jacket and/or insulation.
