Shimadzu Shim-pack GPC Series

Shim-pack™ GPC Series - Size Exclusion Columns

Base Particle Substrate - Polymer - Synthetic high polymers - Determination of Dimethylformamide

Shim-pack GPC series columns are used for the determination of tetrahydrofuran (800 Series), and dimethylformamide (800D series). The technique of GPC does not utilize such chemical reactions as partition, adsorption, and ion exchange, but a physical reaction consisting of a separation based on molecular size of the sample components. Therefore, this method is suitable for the measurement of molecular weight distribution of high polymers and oligomers. Shim-pack GPC series are packed with polystyrene polymers with respective degrees of cross-linking in order to meet exact analysis requirements, ranging from analysis of high polymers to that of oligomers. GPC-80M/80MD are mixed gel columns.
