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

 GPC LF-604 is a size exclusion chromatography 

downsized column for rapid analysis 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.
