Ion Exchange Resins SMHP-210 For High Pure WATER
Product InformationFor the production of ultra high water as non-regenerable mixed bedSMHP-210 is a ready-to-use mixed bed comprsing strongly acidic and strongly basic(type I)gelular cation and anion exchanger. Both components are highly regenerated and specially cleaned. So high purity water can be easily obtained. SMHP-210 is especially applicable to mixed bed systems for OPTICAL ELECTRONICS Semiconductor devices Integrated circut step after DI systems in the production of high pure water.
