气相色谱-质谱法测定辣椒中虫螨腈含量的不确定度评定

Evaluation of Measurement Uncertainty for Residues Determination of Chlorfenapyr in Pepper by Gas Chromatography-Mass Spectrometry

本研究通过建立数学模型,对气相色谱-质谱法测定辣椒中虫螨腈残留量的不确定度进行评定。通过对来源量化以及合成,测得辣椒中虫螨腈残留量为0.68 mg·kg^(-1),包含因子k=2时,扩展不确定度值为0.10 mg·kg^(-1)。

In this study,a mathematical model was established to evaluate the uncertainty of determination of chlorfenapyr residue in capsicum by gas chromatography-mass spectrometry.By quantifying and synthesizing the source,the residual amount of chlorfenacil in pepper was 0.68 mg·kg^(-1), and the extended uncertainty value was 0.10 mg·kg^(-1) when k=2 was included.
