【摘要】 由墨水形成的文件的检验是目前法庭科学实验室经常遇到的问题,因此建立一种简便、灵敏、准确的检验墨水字迹色痕的异同及形成时间的方法是十分必要的。本文采用高效液相色谱法对9种不同产地、不同牌号的蓝黑墨水字迹色痕的提取液进行了种类分析,获得了较好的分析结果。在此基础上,对蓝黑墨水字迹进行了加热、光照的人工老化处理,依据字迹色痕提取液中染料峰面积比值随老化时间的变化,探讨了蓝黑墨水字迹色痕中染料的变化规律,从而为蓝黑墨水字迹形成时间的鉴定奠定了基础。
【Abstract】 The Pen is a writing tool commonly used in criminal and civil cases,often related to fountain pen ink on the identification of handwriting.Identification of the ink writing,with the exception of the ingredients needs to be sure,the people are more concerned about the ink composition changes over time in order to achieve accurate identification of ink formed the purpose of writing.Nine kinds of black - blue inks of different manufacturer and different brand were analyzed,the result is better.Artificial accelerated aging test is a main component of ink in the process of change,is to study the formation of ink writing an important part of the time.By analyzing the conditions of artificial aging changes in composition writing,to explore changes in the law of composition writing,research writing to identify the impact of the formation time,formation time of writing can provide a basis for the identification of artificial aging method(heating,strong light shining,natural light) accelerate the change of the dye compent ,from which the ageing rulers of dye compent in the inks obtained.This research formed a foudation to prove the ages of the writing traces on the copy paper.
