Multisolvent GPC Columns

The GF-HQ series columns are designed for GPC, in which both water and organic solvents can be used as eluents. The highly crosslinked polyvinyl alcohol-based media enables use of a wide range of solvents from water to chloroform for solvent replacement (see the following tables). Offering many eluent options, this series is suitable for analysis of complex samples with both hydrophilic and hydrophobic moieties. In addition to standard columns with ID 7.5mm, we provide micro columns with ID 300micron-800micron, semimicro columns with ID 1.0mm-4.6mm and partition columns with ID 10mm and above.
