Step 1: Choose the right packing material.
DAC columns are controlled by dynamic axial compression, which enables dynamic pressure retention and prevents collapse of the column head, loss of column efficiency and poor reproducibility, etc. If a DAC column loses efficiency after prolonged use, the packing can be pushed out after removal of the column, and the column can be homogenized and loaded again. The whole reloading process is not difficult and takes about 1-2H.
