气相色谱-质谱法自动化检测白酒中17种邻苯二甲酸酯的含量OA
Automated Detection of 17 Phthalate Esters in Liquor by Gas Chromatography-Mass Spectrometry
本研究建立了一种利用全自动样品前处理平台结合气相色谱-质谱(GC-MS)技术自动化检测白酒中17种邻苯二甲酸酯(PAEs)含量的方法.结果表明,17种PAEs在0.02~1.00 μg/mL的线性范围内具有良好的线性关系(相关系数R2>0.998),检出限为0.034~0.065 mg/kg,定量限为0.110~0.216mg/kg,加标回收率在90.82%~115.85%之间,相对标准偏差(RSD)均小于6%.利用本方法对市售的5种白酒样本进行检测,共检出邻苯二甲酸二甲酯(DMP)、邻苯二甲酸二异丁酯(DIBP)和邻苯二甲酸二正丁酯(DBP)3种PAEs.本研究建立的自动化检测方法减少了人为因素对检测结果的影响,提高了检测效率和稳定性,降低了检测成本,为白酒生产企业和质量监管部门提供了有力的技术支持.
This study established an automated method for detecting the contents of 17 phthalate esters(PAEs)in liquor using a fully auto-matic sample pretreatment platform combined with gas chromatography-mass spectrometry(GC-MS)technology.The results indicated that the 17 PAEs exhibit good linearity within the range of 0.02-1.00 μg/mL(correlation coefficient R2>0.998),with limits of detection ranging from 0.034 to 0.065 mg/kg and li1mits of quantification from 0.110 to 0.216 mg/kg.The spiked recovery rates were between 90.82%and 115.85%,and the relative standard deviations(RSD)were all less than 6%.Using this method,three PAEs,namely dimethyl phthalate(DMP),diisobutyl phthalate(DIBP),and dibutyl phthalate(DBP),were detected in five commercial baijiu samples.The automated detection method developed in this study reduces the impact of human factors on the detection results,improves detection efficiency and stability,and lowers detection costs,providing strong technical support for liquor production enterprises and quality supervision departments.
