摘要
本文利用装备有衰减全反射附件的红外光谱仪对62种不同产地、不同品牌的复印纸进行检验,建立了纤维素和无机填料峰面积的比值作为区分鉴别复印纸的新方法,区分度达到了91.96%,达到了无损、快速、准确检验区分的目的。
Abstract
In this paper,we make use of infrared spectroscopy with ATR to study copy papers which often appear in the criminal scene,62 similar type of copy papers from different areas were characterized by infrared spectroscopy.The ratio of the peak area of cellulose and inorganic filler was established as a new method for the identification of copy papers,the degree of differentiation reached 91.96%,which reached the purpose of non-destructive,rapid and accurate inspection.
