水和土壤样品检测过程中质量控制体系探讨

摘要

在水和环境样品的检测过程中，建立一个良好的质量控制体系至少应包括初始能力的证明、能力的持续性证明、方法检出限试剂空白、实验室空白加标、样品基体加标和加标平行、平行样品、内标物、替代物(有机物的分析)或示踪物(放射化学)、标准曲线、控制图、校准措施等。了解这些质控样定义及使用频次是正确使用这些质控手段的前提。%In the process of water and environmental samples test, a good quality control system should include the initial demonstration of capability, ongoing demonstration of capability, method detection limit, reagent blank , blank spike, matrix spike, matrix spike duplicate, sample duplicate, internal standard substance, surrogate for the organic matter or t racer ( radiochemical ) , standard curve, control chart, the calibration measures, etc. It is essential to understanding the definition and frequency of usage of these quality samples during the process of environmental testing.
