GA 12

Strong Base Anion Exchange Resin Type -II

DOSHION GA-12 is a GEL Type -II Strong Base Anion Exchange Resin with high capacity. It is based oncross-linked polystyrene matrix. DOSHION GA-12 is specially designed to give high throughput and economical operation. Trimethyl amine is used to prepare Type -1resin and Dimethyl ethanolamine is used to prepare Type -II resin. Thus the basicity of the Type -II resin is lower than that of the Type -1resin and the hydrophilicity of the Type- II resin is higher than that of the Type -I resin.
DOSHION GA -12is recommended for demineralisation, oxygen removal and nitrate removal .The resins are highly resistant to osmoticshocks and attrition losses and are adaptable for both counter -current and co -current operations.
