摘　　要：目的快速分析不同厂家水基胶中的挥发物特性。方法采用气相色谱-离子迁移谱(GC-IMS)联用技术对各种水基胶中的挥发性物质进行定性分析;结合生物指纹图谱、主成分分析(PCA)法以及欧式距离分析法对不同水基胶样品进行差异对比分析。结果水基胶中共识别出88种挥发性化学物质,涵盖酯类、酮类、醇类、醛类、杂环类、酸类、芳香类、醚类、萜类、酰胺类和腈类等11大类别,其中酯类物质占据显著比例,达26种,占总挥发性物质的38%~46%。结论采用GC-IMS技术结合生物指纹图谱、PCA以及欧式距离分析,能够有效区分不同厂家水基胶样品,同时同一厂家不同规格样品之间显示出较高的相似性;GC-IMS技术为不同厂家水基胶的快速溯源鉴别及挥发性物质差异分析提供了有力工具。The work aims to analyze the characteristics of volatile substances in water-based adhesives from different manufacturers.Gas chromatography-ion mobility spectrometry(GC-IMS)was utilized to qualitatively analyze the volatile substances in various water-based adhesives.Biometric fingerprinting,principal component analysis(PCA),and Euclidean distance analysis were employed to analyze the differences among the different water-based adhesive samples.The water-based adhesive contained a total of eighty-eight volatile chemicals,which were classified into eleven major categories,including esters,ketones,alcohols,aldehydes,heterocycles,acids,aromatics,ethers,terpenes,amides,and nitriles.Among these categories,the 26 esters were the most prevalent,accounting for 38%-46%of the total volatile substances.The use of GC-IMS technology,biometric fingerprinting,PCA,and Euclidean distance analysis allows for effective differentiation of water-based adhesive samples from various manufacturers.Additionally,samples of different specifications from the same manufacturer exhibit high similarity.This technology provides a powerful tool for rapid traceability and identification of water-based adhesives,as well as analysis of differences in volatile substances.
