Dionex IonPac Cryptand C1 離子濃縮柱
如 EPA 方法 314.1 中所述，使用 Thermo Scientific? Dionex? IonPac? Cryptand C1 濃縮柱測定飲用水和高離子強度水中的痕量高氯酸鹽。 這一容量可調的色譜柱包含鍵合了大環(huán) 2,2,2 穴醚化合物的大孔 17.5μm 樹脂。 柱功能容量取決于淋洗液濃度和穴醚化合物內結合的陽離子類型。 可調容量使得 Dionex IonPac Cryptand C1 柱成為測定飲用水和高離子強度水中痕量高氯酸鹽的強大工具。 可配合加壓瓶、注射器、Dionex 自動進樣器和單活塞樣品傳送泵進樣。
描述
將水分析的檢測限降低 2-5 個數量級
Dionex IonPac 和 Thermo Scientific? Dionex? IonSwift? 陰離子濃縮柱主要為高純水分析而設計。 濃縮柱可以從已測得體積的水性樣品基質中保留陰離子，從而濃縮分析物，并將檢測限降低 2-5 個數量級。
色譜分析性能出色
穴醚可用容量約為 30 μeq/柱
容量可根據淋洗液濃度或陽離子類型從固定容量調至零
美國 EPA 方法 314.1 中用于樣品預濃縮。
兼容 Dionex AS、AS-DV、AS-AP、AS-HV 自動進樣器、加壓瓶、注射器和單活塞樣品傳送泵（Thermo Scientific Dionex AXP 輔助泵）

| 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.
