Cation ExchangersAll the cation exchangers offered possess chemical fixed exchanger groups and indicate a very good stability within acid media. Weak cation exchangers bear carboxylic groups, strong exchangers sulfonic groups, usually connected with phenyl residues. The letter H characterizes a special high sulfonated phenyl carrier with an exchange capacity of 0.6 mval/g. The letters PM indicate an ES gel, coated with a polymer layer, with aliphatically connected sulfo groups. Weak cation exchangers WCX| | UltraSep ES WCX44 | | | Simultaneous separation of alkali and alkaline earth ions in the presence of ammonia | Application KATION1 | | | Quick analysis of drinking and industrial water | Application KATION2 | | | UltraSep ES WCX56 | | | | Determination of hydroxylamine simultaneously with ammonia | Application KATION3 | | | UltraSep ES WCXC | | | | In contrast to the exchangers WCX44 and WCX56 in WCXC the component 18-crown-6 is already chemically fixed at the silica gel surface together with the exchanger groups (carboxylic groups). Therefore one can omit addition to the phase. | Application KATION4 |
