环境监测中仪器分析方法不确定度的评估(Ⅰ)

结合我国环境监测的实际情况，通过对环境监测中常用仪器分析方法中测量不确定度的评估，主要对环境监测中常用仪器分析方法不确定度的来源如称量、体积校准、温度波动、标准物质、化学试剂、摩尔质量、工作曲线、方法和仪器重复性、仪器显示和读数、数字修约等作一评述，并指出了环境监测中常用仪器分析方法测量不确定度的评估应注意解决的问题。

Evaluation on Uncertainty of Instrumental Analysis Method in Environmental Monitoring (Ⅰ)

According to the evaluation program of measurement uncertainty, the main sources of uncertainty for common instrumental analysis methods in environmental monitoring including quantification, measurement of solution volume, temperature change, certified values of reference materials, pure chemical reagents, mole mass, calibration curve, analytical method, repeatability of measurement, resolving power of instrument, and numerical rounding procedure were reviewed based on the fact of environmental monitoring in China. The issues and trends for measurement uncertainty of common instrumental analysis methods in environmental monitoring were also investigated.
