避孕套润滑剂的气相色谱-质谱检测方法及分类研究OA

Research on Gas Chromatography Mass Spectrometry Detection Method and Classification of Condom Lubricants

中文摘要英文摘要

本文建立检测避孕套润滑剂中化学成分的气相色谱-质谱联用方法,通过统计学分析,研究不同品牌避孕套润滑剂成分的区别.使用乙酸乙酯提取,气相色谱-质谱联用检测6种品牌17个类型的避孕套润滑剂中所含成分,使用所建立的分类模型,有效识别避孕套品牌、类型.结果表明,在17种类型的避孕套中,共检测出48种成分,相对峰面积的日内精密度为0.14%~13.94%,日间精密度为0.10%~14.14%,重复性为0.13%~14.79%.通过统计学分析,建立的判别分析模型准确率为87.4%.本实验所建立的避孕套润滑剂成分气相色谱-质谱联用的检测方法,操作步骤简便、快捷,提取物质全面、精密度高、重复性好,为司法鉴定中检测性侵案件避孕套的使用及溯源提供了理论依据.

This study aimed to establish a gas chromatography-mass spectrometry(GC-MS)method for detecting the components in condom lubricants,and to identify different brands of condom lubricants through statistical analysis.Ethyl acetate was used as extraction solvent,and the components in 17 types of condom lubricants from 6 commercial brands were detected by GC-MS.A statistical classification model for condom lubricants was established.A total of 48 components were detected,with a relative peak area of inter-day precision of 0.14%to 13.94%,intra-day precision of 0.10%to 14.14%,and repeatability of 0.13%to 14.79%.The accuracy of discriminant analysis is 87.4%.The developed GC-MS detection method features simple operation,rapid analysis,comprehensive substances extraction,high precision,and good repeatability.The successful classification of 17 condom lubricants provided a reliable technical reference and theoretical basis for the detection and traceability of condoms in sexual assault cases investigations.
