Jordi Gel xStream H2O

Jordi xStream H2O columns represent a breakthrough in GPC column technology. This revolutionary column allows for the broadest range of separations currently obtainable with any GPC column. xStream columns were designed for aqueous GPC separations including the analysis of dextrans and polysaccharides. It performs equally well for the analysis of organic soluble polymers including the analysis of polystyrene or other common polymers in THF or chloroform. It is also an excellent choice for the analysis of nylons and poly(ethyleneterepthalate) in hexafluoroisopropanol (HFIP). A single xStream column can be used for aqueous or organic GPC analysis by simply changing solvents.

xStream H2O GPC columns are an excellent column for aqueous GPC analyses. This includes the analysis of a wide range of aqueous soluble polymers including polysaccharides such as dextrans and starches. Other polymers which can be analyzed include butyl methacrylate / isobutyl methacrylate copolymer, phenoxy resin, poly(n-butyl methacrylate), polycaprolactone and poly(isobutyl methacrylate). In addition, the presence of salts in the mobile phase can be used for the analysis of cationic polymers such as quaternary amine polymers.

The broad solvent compatibility of xStream H2O GPC columns allows for their application in all common organic solvents. This includes analyses in polar organic solvents such as DMSO, DMF and DMAC as well as more hydrophobic solvents such as THF and chloroform. Examples of polymer systems which have been analyzed include poly(methyl methacrylate), poly(vinyl chloride), styrene / acrylonitrile copolymer - 32% acrylonitrile, styrene / butadiene copolymer - ABA block - 30% styrene and styrene / butyl methacrylate copolymer.
