(Please read this 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 package and outside of the column for any damage.
(2) Please check if product name and serial number written on the column package, column name tag, and
enclosed Certificate of Analysis (CoA) are matching and correct.
1. Introduction
Thank you for purchasing the Shodex™ product. Shodex OHpak LB-800 series is a size exclusion
chromatography column used with aqueous solvents. The column series is suitable for the separations of
various water-soluble high molecular weight polymers, proteins, and/or oligomers, and molecular weight
distribution analysis of high molecular weight polymers. Successfully reduced baseline noise in the light
scattering (LS) detector by suppressing the column bleeding as much as possible made it to provide accurate
molecular weight measurements. The columns with different exclusion limits are available. Please select
columns with target molecular weight ranges (see below) that meet the molecular weight range of your samples.

Summary of Contents for Shodex OHpak LB-800 Series

  • Page 1 Certificate of Analysis (CoA) are matching and correct. 1. Introduction Thank you for purchasing the Shodex™ product. Shodex OHpak LB-800 series is a size exclusion chromatography column used with aqueous solvents. The column series is suitable for the separations of various water-soluble high molecular weight polymers, proteins, and/or oligomers, and molecular weight distribution analysis of high molecular weight polymers.
  • Page 2 · Shear degradation is more likely to occur in larger molecular weight compounds. When shear degradation occurs, the measured molecular weight may be lower than the actual value or it may influences the repeatability of the analysis. If shear degradation is suspected, use a lower flow rate. SHOWA DENKO K.K. (https://www.shodex.com/)
  • Page 3: Eluent Preparation

    5,000 - 25,000 ≤ 0.5 % 25,000 - 200,000 ≤ 0.25 % 200,000 - 2,000,000 ≤ 0.1 % 2,000,000 ≤ ≤ 0.05 % Note · Use of guard column is recommended to protect the analytical column. SHOWA DENKO K.K. (https://www.shodex.com/)
  • Page 4: Column Installation

    This may result in creating an empty space in the column and deteriorates the column. Note · It is recommended to set the pump limiter to avoid exceeding the maximum pressure. SHOWA DENKO K.K. (https://www.shodex.com/)
  • Page 5: Column Storage

    (a cool and dark space is recommended). Refer to section 7.3 Solvent Exchange for how to replace the eluent. Attention! · Never allow inside of the column to dry. It can damage the column. SHOWA DENKO K.K. (https://www.shodex.com/)
  • Page 6 (2) Do not make a strong impact on the column. Do not drop or hit the column on a hard surface. Refer to the Shodex™ website (https://www.shodex.com/) for product details and their applications.
