Research on Gas Chromatography Mass Spectrometry Detection Method and Classification of Condom Lubricants
摘要
Abstract
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.关键词
