Chromatographic Column

Hanbon medium and high pressure pilot scale chromatography column include DAC
（dynamic axial compression）columns and laboratory columns. In 2005, Hanbon
developed DAC® (dynamic axial compression) column with independent intellectual
property rights, and has built the world's largest production and assembly
workshop for dynamic axial compression columns. The product has been
continuously upgraded and has been recognized by domestic and international
markets, and is exported to more than 20 countries such as India, South Korea,
Norway, Hungary, Germany, the United Kingdom, and Russia. Hanbon provides users
with a dynamic axial compression column with an inner diameter range from 50mm
to 2000mm, providing customized services. Laboratory chromatographic column
include conventional high-performance liquid chromatography columns, spring
columns, dynamic axial compression columns, and multifunctional axial
compression columns.

How Do I Choose A Suitable Preparative Column?

Step 1: Choose the right packing material.

The smaller the particle size the higher the column efficiency, but the higher
the price and the higher the column pressure, requiring higher pressure
tolerance in the equipment hardware.

Step 2: Choose the right bonding phase and pore size.

How to choose the right carbon content and particle size according to the
molecular weight of the substance is a very important issue.

Step 3: Selecting the right column tube.

The sample is to be served in proportion to the cross-sectional area of the
column. The inner diameter of the column is to be selected to suit the sample
serving size.

Step 4: Determine the appropriate flow rate and loading volume

The flow rate of the prepared column: generally proportional to the square of
the diameter.

Sample loading volume: a combination of purification time, solvent usage,
efficiency of the column and sample purity.

Technical Advantages Of DAC

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.
