Jordi Resolve DVB Cation GPC Columns

Jordi Resolve Cation columns apply to the separation of charged polymers without the need for high salt concentrations. These columns are an excellent choice for light scattering analyses, where high salt concentrations compromise system performance. Jordi Resolve Cation columns have a tertiary amine group, which in weakly acidic mobile phases coverts to the positively charged quaternary amine. Common applications include the separation of amine polymers, such as poly(ethyleneimine) in water/acetic acid solutions.
