What ion exchange chemistries are offered by Tosoh Bioscience?
FAQ from TOSOH
Polymer-based columns: Weak and strong anion and cation exchangers are available. These columns are designed with 100 nanometer (nm) pore size and various column sizes ranging from analytical to semi-preparative scale. Also available are BioAssist Q (a polyamine anion exchanger) and BioAssist S (a sulfopropyl cation exchanger), both are very large pore size, high capacity, ion exchangers.
Silica-based columns: Weak and strong anion and cation exchangers are available. These columns are designed with 12.5 nm (upper molecular weight limit of 10 kDa) and 25 nm (upper molecular weight limit 30 kDa) pore sizes.
Specialty columns: Cation and anion exchange ligands are attached to a polystyrene-divinylbenzene (PS-DVB) polymeric support. These are used for separation of carbohydrates, amino acids and organic acids.
