IonPac AS12A 阴离子交换色谱柱 The IonPac® AS12A 是一款中等容量,碳酸盐体系阴离子交换色谱柱,用于快速,等度分离水样中无机阴离子,卤氧化物,包括氟化物, 次氯酸盐, 氯化物, 亚硝酸盐,溴化物, 氯酸盐,硝酸盐, 磷酸盐和硫酸盐. Fast separation of inorganic anions, with excellent retention of fluoride
The IonPac AS12A anion-exchange column provides fast analysis of common inorganic anions and oxyhalides, such as chlorite and bromate, in environmental waters. This column is also useful for trace chloride and sulfate in high-carbonate matrices. • Provides fast analysis of inorganic anions and oxyhalides at similar concentrations • Resolves trace chloride and sulfate high-carbonate samples The AS12A is a moderate-capacity, carbonate eluent anionexchange column designed for the fast, isocratic separation of inorganic anions and oxyhalides, including fluoride, chlorite,bromate, chloride, nitrite, bromide, chlorate, nitrate, phosphate,and sulfate in drinking water, wastewater, groundwater, and other diverse sample matrices. The common inorganic anions and oxyhalides can be determined in less than 12 min using an isocratic carbonate/bicarbonate eluent coupled with suppressed conductivity detection. It resolves chloride from high concentrations of carbonate. Use the Anion Self-Regenerating Suppressor (ASRS 300) with the AS12A column. Note: For trace bromate in ozonated drinking water, use the high-capacity IonPac AS23, recommended for determination of oxyhalides and inorganic anions.
