【摘要】： 由圆珠笔油墨形成的契约、合同、收据和借条等可疑文件的真伪及形成时间的鉴定是目前法庭科学经常遇到的问题,因此建立一种简便、灵敏和准确的检验圆珠笔油墨字迹色痕的异同及形成时间的方法是十分必要的。本论文对国内外不同厂家生产的130支黑色圆珠笔油墨进行了系统的分类研究,涉及到紫外可见分光光度法、极谱法、高效液相色谱法、高效液相色谱-质谱联用、系统聚类分析五种方法。第一章详细评述了近年来有关圆珠笔油墨种类及其字迹色痕形成时间的研究进展。第二章采用高效液相色谱法(HPLC)对黑色圆珠笔油墨的种类进行了研究,根据有色成分的不同对不同品牌的黑色圆珠笔进行分类,同时采用系统聚类分析的方法,对实验结果进行了化学计量学的分析。第三章介绍了黑色圆珠笔油墨字迹色痕的高效液相色谱-质谱法(HPLC- MS)的研究情况。第四章采用紫外可见分光光度法对黑色圆珠笔油墨的种类进行了研究,依据紫外可见光谱图中特征峰位置的不同进行种类的认定。第五章介绍了极谱法在黑色圆珠笔油墨种类研究中的应用,根据不同染料还原峰电位的不同进行分类。第六章总结了本论文的研究工作,指出了论文工作的不足之处,并对该研究工作的未来发展提出了设想。
[Abstract]:The identification of the authenticity and formation time of dubious documents, such as contracts, receipts and debit slips, made of ballpoint ink, is a common problem encountered by forensic science at present, so it is convenient to establish, It is necessary to examine the difference and difference of ink mark and the time of formation. In this paper, 130 black ballpoint pen inks produced by different manufacturers at home and abroad have been systematically classified and studied, including ultraviolet and visible spectrophotometry, polarography, high performance liquid chromatography-mass spectrometry (HPLC), high performance liquid chromatography (HPLC) and mass spectrometry (HPLC). Five methods of systematic cluster analysis. In the first chapter, the progress of the research on the types of ballpoint pen ink and the time of formation of ink mark are reviewed in detail. In the second chapter, the types of black ballpoint pen ink were studied by using high performance liquid chromatography (HPLC), and different brands of black ballpoint pen were classified according to the different color components. At the same time, the method of systematic cluster analysis was used. The experimental results were analyzed by chemometrics. Chapter 3 introduces the research of HPLC- MS for ink mark of black ballpoint pen by high performance liquid chromatography-mass spectrometry (HPLC- MS). In chapter 4, the types of black ballpoint pen ink were studied by ultraviolet visible spectrophotometry, and the types of ink were identified according to the location of characteristic peaks in UV-Vis spectrum. Chapter 5 introduces the application of Polarography in the study of ink types of black ballpoint pen, and classifies it according to the different peak potential of dye reduction. The sixth chapter summarizes the research work of this paper, points out the shortcomings of the research work, and puts forward a tentative plan for the future development of the research work.
