This Standard Reference Material (SRM) is intended for use as an analytical standard of known purity. It is intended primarily for use in the calibration and standardization of procedures for potassium (K) and chloride (Cl‾) determinations employed in clinical analysis, including those using ion-selective electrodes, and for routine critical evaluation of the daily working standards used in these procedures. This lot of potassium chloride (KCl) was prepared to ensure a material of high purity and homogeneity and has been assayed after heating at 110 °C to 120 °C. A unit of SRM 918c consists of a single glass bottle containing 30 g of the material.
本标准参考物质（SRM）旨在用作已知纯度的分析标准。它主要用于校准和标准化临床分析中使用的钾（K）和氯（Cl‾）测定程序，包括使用离子选择电极的程序，以及对这些程序中使用的日常工作标准进行常规关键评估。这批氯化钾（KCl）的制备是为了确保材料的高纯度和均匀性，并在110°C至120°C加热后进行了分析。SRM 918c的一个单元由一个装有30g材料的玻璃瓶组成。
