FAQ
How Should I Store Styragel GPC Columns? If the column needs to be stored for less than 24 hours before it will be used again, no special storage considerations or procedures are necessary as long as you take care that the columns never dry out. When longer storage periods are necessary, the column should be returned to the box with the end plugs firmly in place before being stored. Columns should not be left at elevated temperatures when there is no solvent flow.
To ensure maximum column life, avoid temperature cycling. It is helpful to maintain operating temperature and reduce the flow rate to 0.1 mL/min when columns are not being used.
In order to restart the column, maintain a flow rate of 0.1 mL/min and increase the temperature gradually over 10 hours, then set the flow rate to the desired operating flow.
