Ion exchange foams to remove ions from samples

A method of making an ion exchange foam is described. The method includes forming an aqueous phase by suspending an ion exchange resin in an aqueous solvent. An organic phase is formed by mixing at least a divinylbenzene, a monomer, and a surfactant. The formed aqueous phase is mixed with the formed...

Beschreibung
Zusammenfassung:	A method of making an ion exchange foam is described. The method includes forming an aqueous phase by suspending an ion exchange resin in an aqueous solvent. An organic phase is formed by mixing at least a divinylbenzene, a monomer, and a surfactant. The formed aqueous phase is mixed with the formed organic phase to form an emulsion. The emulsion is polymerized to form the ion exchange foam. The ion exchange foam can be used with a plurality of sample vials in an autosampler.
