气相色谱法测定橄榄中三唑酮残留量的不确定度评定

Uncertainty Evaluation of the Residues of Triadimefon in Olive by Gas Chromatography

介绍了气相色谱法测定橄榄中三唑酮残留量的不确定度评定方法。结果表明,测量过程中三唑酮残留量的不确定度主要来源于校准过程、重复性测量和回收率;当橄榄三唑酮含量为0.072 21 mg·kg-1时,扩展不确定度U=0.005 576 mg·kg-1(k=2)。

Uncertainty evaluation for the residues of triadimefon in olive by gas chromatography was introduced. The results showed that the calibration process, measurement repeatability and recovery were the main sources of uncertainty, and the expanded uncertainty was 0.005 576 mg·kg^-1 （k=2） as the residues of triadimefon in olive was 0.072 21 mg·kg^-1.
