PSS SDV gel column

PSS SDV column: suitable for organic wash solution

PSS SDV gel is a kind of macroporous network formed by copolymerization of styrene and divinylbenzene, which is gestalt, pressure resistant and stable to PH value. This column applies the progress of chemical synthesis and analytical testing technology, and is designed for efficient separation. The column can be divided into different models according to the different particle sizes of gel materials (3, 5, 10 and 20 μ m, etc.), and can be applied in a wide range of molecular weights. This product is suitable for analyzing additives, oligomers, synthetic polymers, ultra-high molecular weight polymers, and sample pretreatment.

SDV-HR gel: suitable for samples with molecular weight less than 100000D, such as monomers, oligomers, etc. If the viscosity of the eluent is low, the separation effect is better.

SDV5 μ gel: This high-quality gel material has a good separation effect and can be used in most occasions to separate samples of various molecular weight ranges.

SDV10 μ gel: * for high molecular weight samples (M_w>1000000D) and viscous, non swelling eluents (such as DMF, NMP, DMSO). This material is suitable for making efficient preparation columns.

SDV20 μ gel: suitable for semi preparative columns and ultra-high molecular weight samples.

linear Gel: This gel can separate samples with a wide molecular weight distribution, typically used to remove unknown ingredients in products. The gel is suitable for the occasions requiring rapid separation.
