实验室用一次蒸馏水质量好坏直接影响化验结果的准确性,特别是对微量元素测定的精密仪器室尤为重要。作为测定微量元素配制标准溶液所用的蒸馏水,S iO2含量是一项重要质量控制指标。根据GB/T 6682分析实验室用水规格标准,采用硅钼蓝分光光度法分析。该方法分析时间长,前处理操
Laboratory distilled water quality directly affects the accuracy of laboratory results, especially for the determination of trace elements of the precision instrument room is particularly important. As a measure of trace elements preparation of standard solution used in distilled water, S iO2 content is an important quality control indicators. According to GB / T 6682 analytical laboratory water specifications, the use of molybdenum blue spectrophotometric analysis. The method of analysis for a long time, pre-treatment operation
