PSS NOVEMA – The ideal GPC column for all types of Polycations

PSS NOVEMA is the right choice for polycation applications. The column packing is based on hydroxyethylmethacrylate. Due to the absence of charged groups on the surface, the material is also ideal for universal calibrations. The chemical structure allows to use low concentration of buffers and in a lot of cases, organic modifiers can be avoided. This is perfect for light scattering measurements. Typical applications are Poly(DADMAC), Chitosan or all type of acrylate based cationic copolymers. The columns is available in individual porosities (30, 300, 1.000, 3.000, 10.000 Å) to cover a separation range from 100 to > 5 Million Dalton. The application attached shows a comparison of two Poly(DADMAC) samples with Mp of 310.000 D (red curve) and 210.000 D (blue curve). The eluent used is 0,3 M formic acid.
