摘要:
采用气相色谱-三重四极杆质谱联用法测定核桃油中酚类抗氧化剂,分析不确定度的来源,建立评估的数学模型,通过计算不确定度的各主要分量,给出了3 种酚类抗氧化剂测定结果的扩展不确定度。评定结果表明:影响检测结果不确定度的主要因素为标准品的纯度和样品的回收率。该评估模型为气相色谱-三重四极杆质谱联用法的不确定度评估提供了参考依据。
关键词: 气相色谱-三重四极杆质谱联用法, 不确定度, 核桃油, 酚类抗氧化剂
Abstract:
The sources of uncertainty in the determination of phenolic antioxidants in walnut oil by gas chromatographytriple quadrupole mass spectrometry (GC-MS/MS) were analyzed, and a mathematical model for uncertainty evaluation was established. The major uncertainty components were calculated and used to obtain the expanded uncertainties for the results of determination of three phenolic antioxidants. The major uncertainty sources were determined as the purity of standard substance and recovery of sample. This study can provide a reference for uncertainty evaluation of GC-MS/MS analysis.
Key words: gas chromatography-triple quadrupole mass spectrometry (GC-MS/MS), uncertainty, walnut oil, phenolic antioxidants
