描述
测定超纯水中的痕量级硼酸盐
硼酸盐是阴离子交换材料中保留最弱的阴离子之一,也是能够穿透多种水净化系统的首种物质。 在发电和半导体行业,监测痕量硼酸盐可用于测定水处理系统的效率。 离子排斥方法与抑制电导检测结合,可以为此类应用提供一体化解决方案。
实用的连续监测
此款易于使用的硼酸盐色谱分析系统可以明显提高痕量溴酸盐检测的实用性和可靠性。检测中,样品首先通过 Dionex IonPac TBC-1 浓缩柱。 样品浓缩后,依序切换为分析柱以进行洗脱和检测。
抑制电导检测可以提高灵敏度
用 途 和 特 点 :
IonPac ICE-Borate 离 子 排 斥 柱 用 于 分 析 高 纯 水 中 的 痕 量 硼 酸 盐 。使 用 TBC-1
浓缩柱,电导检测器,检测硼酸盐可低至ng/L(ppt)浓度水平。

Ion-Exclusion Column Ideal for Monitoring Trace Levels of Borate in
High-Purity Water
The IonPac ICE-Borate ion-exclusion column is designed for monitoring trace
levels of borate in high-purity water.
Used with the TBC-1 Borate Concentrator column and conductivity detection,
the ICE-Borate ion-exclusion column allows determination of borate at ng/L (ppt)
concentrations. Borate is separated and detected as the mannitol complex. Use
the Anion MicroMembrane Ion-Exclusion Suppressor (AMMS? ICE 300) with
the ICE-Borate column.
