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 GPC LF-604 is a size exclusion chromatography
column used with organic solvents. LF-604 is packed with unique multi-pore gels with a wide pore-size
distribution. It provides a high linear calibration curve without inflection points. It is suitable for molecular weight
distribution analysis of polymers having a broad molecular weight distribution.

  • Page 2: Eluent Preparation

    · Always use freshly prepared solvents. Solvents stored for a long time may have changed their compositions and may influence elution patterns and/or damage the column. Note · Use of an on-line degasser is recommended. Resonac Corporation (https://www.shodex.com/)

  • Page 3: Sample Preparation

    (2) Make sure to insert the tubing all the way to the end fitting and secure it with the male nut. It is important that there is no extra space between the tubing and the column side of the end fitting. Presence of an extra space will let the sample to spread out and may result in wide peaks. Resonac Corporation (https://www.shodex.com/)

  • Page 4: Column Cleaning

    (i.e., do not let the solution go through the detector). If the column performance does not improve (recover) after performing the column cleaning, please replace the column with a new one. 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...
