【摘要】 目前用于水溶性墨水的检验技术,多限于种类区分,还不够完善。作者通过实验研究,提出了一种新的检验方法:用色谱法、紫外导数光谱法,分析鉴别15种不同厂家生产的不同牌号的黑色签字笔墨水。结果表明,纸张没有干扰,试剂空白不影响鉴别。该方法可以有效地用于签字笔墨水书写时间的鉴定,有助于弥补现行方法的缺陷。更多还原

【Abstract】 Conventional methods employed in identifying black signing ink are limited in variety distinguishing, requiring further improvement. We propose a novel method based on experimental study. Fifteen five kinds of black signing inks, from different factories, are analyzed by using chromatography and ultraviolet spectrophotometry (UV-Vis). It is concluded that the pictures do not interfered by the paper difference and the non-reagent areas do not affect the identification results. This method could be used effectively for time identification of documents written with signing inks. It is helpful to remedy the shortcoming of conventional methods.更多还原
