ResinTech SIR-110-MP-HP is a buffered chloride form PFAS, perchlorate, and nitrate selective macroporous strong base anion resin. Its unique functionality greatly increases the selectivity for nitrate while greatly decreasing the interference from sulfate ions. SIR-110-MP-HP is recommended for the removal of perchlorate, nitrate, and some perfluorinated (PFAS) compounds. Its 'HP' designation indicated it has been Gold Seal certified by the WQA for use with drinking water applications. The buffered chloride form mitigates the pH drop at startup.
