Guide to analytical quality control for water analysis 水质分析的分析质量控制(AQC)指南
It is suggested that analytical quality control technique should be used in soil background survey. 建议在土壤背景值调查中试用分析质量控制(AQC)。
Corn reference materials were prepared and certified for fluoride content ( two concentrations ) according to the need of analytical quality control in monitoring coal smoke fluoride pollution. 本文根据目前国内煤烟氟污染监测工作中对质量控制的要求,研制了玉米中氟成分标准物质(两种氟浓度)。
Meanwhile, the bioavailability and mobility of the selected heavy metals in typical soil samples were assessed by BCR three-steps sequential extraction procedure, soil certified reference materials ( BCR & 701 ) were used for analytical quality control. 同时,本文选取代表性土壤样品,采用欧共体标准测量与检测组织的BCR三步逐级提取法分析了土壤中6个重点元素的化学形态,采用BCR土壤标样(BCR-701)控制分析质量。
