Multimode Columns

The GS-HQ series columns can be used in multiple modes of GFC, distribution/adsorption and ion exchange. The columns can be used for GFC in selected eluent conditions. In addition, multi-mode use, including the distribution/adsorption and ion exchange modes, enables unique fractionation. 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 preparative columns with ID 10mm and above.
