(Please read this operation manual carefully to achieve the best and consistent column performance for a long time.)
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.
1. Introduction
Thank you for purchasing the Shodex product. Shodex Asahipak GS-HQ series is polymer-based size
exclusion chromatography (SEC) columns. With the choice of eluent, the column provides multimode features
of reversed phase chromatography, hydrophilic chromatography (HILIC), and ion exchange chromatography in
addition to SEC. The column series is suitable for the separations of peptides or nucleic acids with similar
molecular weights.

With the choice of eluent, the column provides multimode features of reversed phase chromatography, hydrophilic chromatography (HILIC), and ion exchange chromatography in addition to SEC.
  • Page 2: Eluent Preparation

    (2) Filter diluted sample solutions using disposable 0.45-μm filters to prevent the column from clogging or deteriorating. (3) Suggested injection volume is 50 to 100 μL per column. Resonac Corporation (https://www.shodex.com/)
  • Page 3: Column Installation

    · Verify that there is no solvent leak. The solvent leak may cause electronic leakage, rust, and/or chemical injury. Attention! · Make sure not to let air bubbles enter the column while installing the column. The air bubbles may damage the column. Resonac Corporation (https://www.shodex.com/)
  • Page 4 Method 1: Adsorption of hydrophobic compounds (when using aqueous eluent) Introduce the eluent with a high polar organic solvent (acetonitrile or methanol). Method 2: Adsorption of ionic compounds Introduce the eluent with a higher salt concentration. Resonac Corporation (https://www.shodex.com/)
  • Page 5: Column Storage

    · 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...
