摘　　要：运用傅里叶变换红外光谱、显微激光拉曼光谱以及紫外-可见光谱仪等多种光谱学手段测定了纸张上蓝色签字笔墨水的光谱,并根据吸收峰的差异对收集到的28种不同品牌、系列的蓝色签字笔进行了分类。同时还结合热重-质谱联用研究了人为老化过程中纸张上签字笔墨水成分的变化。讨论了上述谱学方法在分析鉴别纸张上蓝色签字笔墨水种类及成分的优劣,以及在研究相对书写时间和绝对书写时间中的潜在应用。Multi-spectroscopy,such as FTIR,dispersive Raman spectroscopy and UV-Vis,was applied to characterize the blue gel pen inks on paper at the time in the present study.Twenty eight collected blue gel pens with different brands and serials were separated into four different classes by different absorptions or Raman shift.Composition changing of blue gel pen inks on paper during artificial ageing was studied via TD-MS as well.The advantage and disadvantage of this spectroscopy used in analyzing and identifying blue gel pen inks on paper,and the potential application in the research on relative and absolute ageing of documents were discussed.
