摘要: 摘 要:通过气相色谱法(GC)和气相色谱-质谱法(GC/MS)测定茶叶中的联苯菊酯,对测定过程中可能引入的不确定度进行了分析和评定。根据《测量不确定度评定与表示》(JJF1059-1999)中有关规定,建立了不确定度评定的数学模型,对各分量在构成合成不确定度时的影响率进行分析,得出不确定度控制的关键在于控制好样品的前处理和标准曲线.

Abstract: Abstract: Determination of bifenthrin in tea by gas chromatography (GC) and gas chromatography - mass spectrometry (GC / MS), uncertainties originated from the measurement have been evaluated.According to "Evaluation and Expression of Uncertainty in Measurement" (JJF1059-1999) in the relevant regulations, created the mathematical model of uncertainty .From the analysis of contribution rate which was calculated by different components combined to the combined uncertainty,the testing key issure for quality control was the sample pre-treatment and the standard curve.

Key words: gas chromatography(GC), gas chromatography-mass spectrometry(GC-MS), bifenthrin, uncertainty, tea
