Important Handling Instructions
Caution!
· Please consult the Safety Data Sheet (SDS) of reagents and solvents used with the column
and understand their proper handling methods to prevent potential health hazards or death
from occurring.
· Please wear appropriate personal protective equipment such as lab goggles and gloves
when handling organic solvents and acid and alkaline reagents. Avoid any direct physical
contact to prevent chemical injuries.
Before Using the Column
(1) Please visually inspect the column package and the column surface for any damage.
(2) Please check the product name and serial number (Serial no. or S/N) written on the column package and
adhesive label on the column body.
(3) Please download the Certificate of Analysis (CoA) for the purchased product. The CoA can be downloaded
from Shodex website (https://www.shodex.com/download/). You will be asked to enter the serial number.

    It may lead to abnormal peak shapes, poor separations, and/or low reproducibility. In such cases, please adjust the sample concentration and/or the injection volume. Note · Use of a guard column is recommended to protect the analytical column. Resonac Corporation (https://www.shodex.com/)
  • Page 3: Column Installation

    7. Column Usage Procedure HILICpak VG-25 2B is a semi-micro column. To achieve its best performance, please use it with a semi- micro type HPLC system. 7.1 HPLC System Preparation Wash the entire HPLC system prior to column installation, including all flow-lines and sample loop by switching the valves, and then replace the washing solution with the eluent to be used.
  • Page 4 (2) Follow below cleaning steps for adsorbing components. For an efficient cleaning, reverse the flow direction. Set the flow rate at 0.1 mL/min. Method 1: General cleaning Washing Solution Cleaning Time 5 min 0.1 M NaOH aq. solution 15 min 60 min Eluent 60 min Resonac Corporation (https://www.shodex.com/)
  • Page 5 · Never allow inside the column to dry. It can damage the column. 9. Column Inspection Please refer to the inspection method described in the CoA. At Shodex, “half width method” is adopted for the calculation of plate count and “asymmetry factor (Fas)” is adopted for the calculation of peak symmetry. Please refer to the Shodex website for the detail: https://www.shodex.com/en/da/07.html...
