离子色谱仪实验用水探讨
Discussion of the Water for Ion Chromatography

本次研究使用实验室制备的电阻率为13.9 ΜΩ？cm (25℃)的实验用水，参照环境监测阴阳离子测定的相关标准方法，配制离子色谱仪的淋洗贮备溶液、淋洗液、混合标准使用液、标准曲线点溶液，以测定标准曲线、检出限、空白样、有证标样、实样、实样加标回收率等相关技术指标。验证了实验用水在电阻率为13.9 ΜΩ？cm (25℃) (即≤18 ΜΩ？cm)时，可满足环境监测相关标准中质量保证要求，此结论可为无能力制备电阻率 ≥ 18 ΜΩ？cm (25℃)超纯水的实验室提供实验参考。
This article uses the water of the resistivity is 13.9 ΜΩ？cm (25？C) prepared in the laboratory, prepare elution stock solution, elution solution, mixed standard solution, and standard curve point solution for ion chromatography to determine the recovery rates of calibration curve, detection limit, blank samples, certified standards, real samples, and real sample spiked solutions, referring to the relevant standard methods for measuring anions and cations in environmental monitoring. Verified that the experimental water has a resistivity of 13.9 ΜΩ？cm (25？C) (resistivity ≤ 18 ΜΩ？cm (25？C)), it can also meet the quality assurance requirements in environmental monitoring standards, this conclusion can provide experimental reference for laboratories that are unable to prepare ultrapure water (resistivity ≥ 18 ΜΩ？cm (25？C)).
