Malvern Panalytical I-GUARD-0478 Polar Organic Column CLM1019

I-GUARD-0478 Polar Organic Column CLM1019 is a guard/ inert (I-) column designed for GPC/SEC analysis of polymers soluble in polar organic solvents. The column is intended to reduce sample–column interaction and protect analytical columns in workflows using polar organic mobile phases (examples include DMF, dichloromethane and DMSO) and formic acid. It is supplied as part of the Malvern Panalytical Viscotek GPC/SEC column range for polar organic applications.

Key Features:

• Product identifier: I-GUARD-0478, part code CLM1019
• Particle size: 10 µm
• Exclusion limit (polystyrene): 20,000 Da
• Maximum pore size: 1,000 Å
• Compatible with polar organic solvents (e.g., DMF, DCM, DMSO) and formic acid; shipped in DCM

Advantages:

• Reduces interaction between sample and analytical column, improving chromatographic integrity for polar-organic analyses
• Functions as a guard column to protect downstream analytical columns and extend their operational life
• Designed for use with polar organic mobile phases, enabling reliable separations of polymers dissolved in solvents such as DMF, DCM and DMSO
