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 GPC LF-804 is a size exclusion chromatography
column used with organic solvents. It is packed with unique multi-pore gels with a wide pore-size distribution.
Therefore it can be obtained highly linear calibration curve without inflection points. The column is suitable for
analysis over a broad range of molecular weights.

  • Page 1 Certificate of Analysis (CoA) are matching and correct. 1. Introduction Thank you for purchasing the Shodex product. Shodex GPC LF-804 is a size exclusion chromatography column used with organic solvents. It is packed with unique multi-pore gels with a wide pore-size distribution.
  • 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 · If the eluent left in the system is not compatible with the column to be used, it may damage the column. · A drastic change in the eluent compositions may remove substances adsorbed on the system and they may enter and deteriorate the column. SHOWA DENKO K.K. (https://www.shodex.com/)
  • Page 4 When replacing THF to DMF with LiBr, first follow step (3) above, and then replace 100 % DMF to DMF with LiBr. Attention! · Frequent solvent replacement deteriorates the column, and thus not recommended. SHOWA DENKO K.K. (https://www.shodex.com/)
  • Page 5 (2) Do not make a strong impact on the column. Do not drop or hit the column on a hard surface.
