石墨炉原子吸收光谱法测定番茄酱中铅含量*的测量不确定度分析

Analyses on Uncertainty Measurement of GF-AAS Measuring the Lead in the Ketchup

通过番茄酱中铅含量的重复性测试结果,计算实验标准差,分析并计算了测试过程中系统效应产生的不确定度分量的值,达到了对番茄酱中铅含量的测量不确定度的合理评定,并对合成标准不确定度进行了适度扩展。求出番茄酱中铅含量的安全的扩展不确定度。

By the result of repeated tests on the lead of the ketchup, the paper calculated the standard deviation of the experiment, analyzed and calculated the value of the standard uncertainty that the systematic effect produces in the course of testing, and reached the rational evaluation of standard uncertainty of measurement on the lead of the ketchup, and expanded appropriately to combined standard uncertainty.
