P313 Weak-Base (Gel) Acrylic Anion Exchange Resin
详细说明
1. Description
P313 is a high capacity, shock resistant ,acrylic gel ,weakly base anion resin. Supplied in the free bass form as moist, tough, uniform spherical beads. S313has tremendous regeneration efficiency and low rinse requirement and is also capable of reversibly adsorbing large organic ions.P313is intended primarily for use in multiple bed deionization ,pharmaceutical , and food grade process applications.
