如 EPA 方法 314.1 中所述,使用 Thermo Scientific? Dionex? IonPac? Cryptand C1 浓缩柱测定饮用水和高离子强度水中的痕量高氯酸盐。 这一容量可调的色谱柱包含键合了大环 2,2,2 穴醚化合物的大孔 17.5μm 树脂。 柱功能容量取决于淋洗液浓度和穴醚化合物内结合的阳离子类型。 可调容量使得 Dionex IonPac Cryptand C1 柱成为测定饮用水和高离子强度水中痕量高氯酸盐的强大工具。 可配合加压瓶、注射器、Dionex 自动进样器和单活塞样品传送泵进样。
将水分析的检测限降低 2-5 个数量级
Dionex IonPac 和 Thermo Scientific? Dionex? IonSwift? 阴离子浓缩柱主要为高纯水分析而设计。 浓缩柱可以从已测得体积的水性样品基质中保留阴离子,从而浓缩分析物,并将检测限降低 2-5 个数量级。
色谱分析性能出色
穴醚可用容量约为 30 μeq/柱
容量可根据淋洗液浓度或阳离子类型从固定容量调至零
美国 EPA 方法 314.1 中用于样品预浓缩。
兼容 Dionex AS、AS-DV、AS-AP、AS-HV 自动进样器、加压瓶、注射器和单活塞样品传送泵(Thermo Scientific Dionex AXP 辅助泵)

IonPac Cryptand C1 Concentrator Column (4 x 35 mm) | 062893 |
The IonPac? Cryptand C1 Concentrator Column is recommended for the analysis of trace perchlorate in drinking water. This adjustable-capacity column contains a macroporous, 17.5 μm resin grafted with the macrocyclic 2,2,2 cryptand compound. The column’s functional capacity depends on eluent concentration and the type of cation bound within the cryptand molecule.
Approximately 30 μeq/col of cryptand capacity available for use
Capacity adjustable from fixed amount to zero by via eluent concentration or cation type
The adjustable capacity makes the Cryptand C1 a powerful tool for determining trace perchlorate in drinking water and high ionic strength water. Methods using the C1 can quantify 140 ng/L of perchlorate in a background of total dissolved solids with concentrations as high as 3000 mg/L. The Cryptand C1 is specified for sample preconcentration in US EPA Method 314.1.
