Caution :
On the glass column s application, the pressure at the top of the column should be
less than 30 MPa to prevent the damage of the glass column and the leakage of the
gel at the end fitting.
7. Temperature
The optimal operating temperature for HIC type columns is between 10-30 ℃.
These columns should not be used above room temperature for long time.
Below 10℃, use a lower rate to protect the columns.
For long term storage the columns should be stored at room temperature.
8. Guard Column
When impurities that tend to be adsorbed by the packing material present in the
sample, they are adsorbed on the inlet side of the column and accunulate gradually,
causing reduction of column efficiency.
In such case the original column efficiency can be maintained by connecting a guard
column before the column and replacing it if efficiency becomes degraded by the
adsorption of material to the guard column.
For mazimum insurance against such problems, a guard column should be used as
much as possible.
We prepared the Guard column kit as the guard columns for TSKgel Phenyl-5PW
and Ether-5PW.
