Dynamic Axial Compression Column System (DAC)

The DAC column has been developed for production or research and can be charged automatically.
The DAC column compresses the column bed with a hydraulic cylinder.

Characteristics of DAC Columns

1. Distribution plates and collecting plates have been developed with independent design and special processing techniques. As a result, the column performance is excellent.
2. A typical prep HPLC column may cause void due to long time use. However, the DAC column does not produce void because the piston head compresses the column bed to a constant pressure at all times.
So the performance of the column is long maintained.
3. Using an instrument that automatically supplies slurry, column packing can be done automatically.
4. Power sources can use compressed air and electricity.
Pneumatic pumps can maintain column performance for a long time because it compress the column bed with the pump pressure.
An explosion-proof electric drive motor may be used if the noise is annoying.
5. Packing using a pneumatic pump in a DAC column with a diameter of more than 800mm takes a long time to pack because there are limitations in flow rate and pressure.
However, the hydraulic station can quickly packing the column.
And after packing, use a pneumatic pump to maintain pressure.
