True microporous membranes with controlled charged capacities and excellent mechanical wet strength

• Hydrophilic membranes are easily digestible. This eliminates need to elute ions from membranes, eliminates chemical waste, and saves time.
• I.C.E. 450® membrane is a strongly acidic, negatively-charged membrane filter. Ion exchange capacity is provided by a patented post-treatment process. Supplied in the hydrogen ion form of the sulfonic acid (functionality) active sites.
• SB-6407 membrane is a strongly basic, positively-charged membrane filter with quaternary ammonium groups. Supplied in the chloride ion form.

• Suitable for trace metal analysis of power plant cooling water and boiler feed water.
