IonPac AS12A 阴离子交换色谱柱 Dionex 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.Dionex™ IonPac™ AS12A IC 柱一款中等容量的色谱柱,适用于无机阴离子和卤氧化物。Dionex IonPac AS23 色谱柱是该色谱柱的新型替代品。高碳酸盐基质中的痕量氯化物和硫酸盐。从环境样品中分离无机阴离子和卤氧化物,例如氯化物和溴化物。Thermo Scientific™ Dionex™ IonPac™ AS12A 分析和保护柱溶解高碳酸盐样品中的痕量氯化物和硫酸盐,符合或超过美国 EPA 方法 300.0(A)和(B) 的要求。然而,先进的高容量 IonPac AS23 碳酸盐洗脱液阴离子交换柱推荐用于卤氧化物和无机阴离子的测定,如臭氧消毒饮用水中的痕量溴酸盐快速等度分离多种基质中的无机阴离子和卤氧化物按照美国 EPA 方法 300.0 (A) 和 (B) 中的规定,对饮用水中常见阴离子进行合规监测12 分钟内对常见无机阴离子和卤氧化物进行分离,包括亚氯酸盐、溴酸盐和氯酸盐优异的氟化物保留和定量分析能力高碳酸盐样品中氯化物和硫酸盐的痕量分析溶剂兼容性让您在分析含有疏水成分的样品后方便地进行柱清洗。提供多种规格,实现应用灵活性4x200mm、2x200mm 分析柱4x50 mm、2x50 mm 保护柱较长的 200mm 柱可实现复杂样品基质的更高分辨率分离更小柱内径提供更高质量灵敏度,节省洗脱液和试剂,从而降低运行成本Fast Separation of Inorganic Anions, with Excellent Retention of FluorideThe 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 concentrationsResolves trace chloride and sulfate high-carbonate samplesThe AS12A is a moderate-capacity, carbonate eluent anion-exchange 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.IonPac AS12A Anion-Exchange Column SpecificationsDimensionsIonPac AS12A Analytical Column:2 × 200 mm and 4 × 200 mmIonPac AG12A Guard Column:2 × 50 mm and 4 × 50 mmMaximum operating pressure4000 psiMobile phase compatibilitypH 0–14 0–100% HPLC solventsSubstrate characteristicsBead Diameter: 9.0 μmPore Size: 2000 ?Cross-Linking (%DVB): 55%Latex characteristicsFunctional Group: Alkyl quaternary ammonium ionLatex Cross-Linking: 0.2%Latex Diameter: 140 nmHydrophobicity: Medium hydrophobicCapacity13 μeq (2 × 200 mm analytical column)1 μeq (2 × 50 mm guard column)52 μeq (4 × 200 mm analytical column)4 μeq (4 × 50 mm guard column)Column constructionPEEK with 10-32 threaded ferrule-style end fitting.All components are nonmetallic 订购信息:Analytical ColumnsIonPac AS12A Analytical Column (4 x 200 mm)046034IonPac AS12A Analytical Column (2 x 200 mm)046055Guard ColumnsIonPac AG12A Guard Column (4 x 50 mm)079801IonPac AG12A Guard Column (2 x 50 mm)046056应用谱图:
