Dionex IonPac CS12A-8μm 和 CS12A-5μm 毛细管柱提供相同的选择性、分析范围以及同样低的运行成本。
建议用于各种样品基质中常见阳离子和铵的分析
水源水和饮用水、市政和工业废水、土壤萃取物、酸性消化物
工业冷却水、洗涤液；电镀槽；以及工业溶剂
用铵或吗啉处理的发电厂水；化学添加剂；化学过程溶液
更低的洗脱液要求，降低运行成本
由于使用相同的填料，因此 Dionex IonPac CS12A 毛细管柱提供的性能与标准孔和微孔 Dionex IonPac CS12A 柱相同。 由于毛细管系统运行的洗脱液流速仅为标准孔系统的 1%，需要的洗脱液更少，产生的废物也更少，从而降低运行成本。
提供多种规格，实现应用灵活性
4x250 mm、2x250 mm、3x150 mm 或 2x100 mm 分析柱
4x50 mm 或 2x50 mm、3x30 mm 保护柱

The IonPac? CS12A is a medium-capacity, carboxylate-functionalized cation-exchange column recommended for fast, isocratic separation of lithium, sodium, ammonium, potassium, magnesium, and calcium using methanesulfonic or sulfuric acid eluents in diverse sample matrices.
The new CS12A-8μm and CS12A-5μm Capillary Columns offer the same selectivity as their analytical-scale counterparts, but offer the advantage of reduced eluent consumption, thereby lowering operating costs.
Robust, reliable column for separation of group I and II cations plus ammonium
Recommended for separation of manganese and morpholine
Recommended for analyses of inorganic cations in complex matrices
Simplified Reagent-Free IC operation provided by the EG or eluent regeneration
Compatible with organic solvents (except alcohols), high temperatures, and high acid concentrations
Analysis time for six common cations as short as 4 min (CS12A-5μm) to 15 min (CS12A-8μm)
The CS12A-MS column offers fast elution at the low flow rates required for IC-MS, making it ideal for IC-MS screening
For disparate concentration ratios of adjacent-eluting cations, the high-capacity IonPac CS16 is recommended
The medium-capacity IonPac CS12A cation-exchange column supports fast, isocratic separation with suppressed conductivity detection. Sample matrices include environmental and drinking waters; soil extracts; acid digests; power plant waters treated with ammonium or morpholine; chemical additives; chemical process solutions; scrubber solutions; plating baths; and industrial solvents.
Use the CS12A-5μm columns for high efficiency and fast analysis (4 min). The smaller-diameter resin technology and reduced column length provide faster analysis time, reduced eluent consumption, and increased sensitivity. The CS12A column is the recommended replacement for all CS12 applications. Use the CS12A column with the Eluent Generator for simplified methanesulfonic acid eluent preparation.
