摘　　要：建立了一种傅里叶变换衰减全反射红外光谱法(ATR-FTIR)结合气相色谱-质谱联用法(GC-MS)鉴别印章印文的方法。结果表明,在波数4000~1700 cm-1范围内,根据其红外光谱图特征峰的个数及峰位置可将15种样品分为5类;结合气相色谱-质谱联用法,可以有效区分同一品牌不同型号及不同品牌不同型号的样品。该方法具有样品制备简单、分析速度快、价格低廉、自动化程度高的优点,为物证鉴定中印章印文的鉴别提供可靠的检验方法,对物证鉴定中的文件检验分析具有较强的实践应用价值。An Attenuated Total Reflection Fourier Transform Infrared(ATR-FTIR)combined with Gas Chromatography-Mass Spectrometry(GC-MS)was developed to identify seals.The results showed that in the range of 4000 to 1700 cm-1,the samples are divide into five categories according to the number and peak position of characteristic peaks in IR spectra.Combined with GC-MS,it can effectively distinguish samples of different models of the same brand and samples of different brands and models.This method has the advantages of simple sample preparation,fast analysis speed,low price and high degree of automation.It provides a reliable inspection method for the identification of seals in the identification of physical evidence and has strong practical application value for the inspection and analysis of documents in the identification of physical evidence.
