摘要

对聚合物材料进行传统的法医化学比较时,往往会受到指纹印剂的影响,因为指纹印剂会增强指纹痕迹并使其可视化。这可能会妨碍用于关联或区分两种样品的详细分析。在本研究中,我们证明了利用同位素比质谱分析进行聚合物比较的方法不会受到表面指纹物质的影响,这一点与其他法医仪器测试不同。我们对一些可重新密封的袋子进行了分析,以确定经过各种指纹鉴定剂处理的袋子的碳和氢同位素比值,并与未经处理的袋子的比值进行比较。结果表明,打过指纹的样本与未打指纹的样本没有明显差别。

The effects of fingerprinting agents on the stable isotope ratios of polyethylene films

Traditional forensic chemical comparisons of polymeric materials are often affected by fingerprinting agents that enhance and visualise finger-marks. This can inhibit detailed analysis used to provide an association or discrimination between two samples. In this study, we have demonstrated that the method for polymer comparisons using isotope ratio mass spectrometry analysis is not affected by fingerprinting matter on the surface in contrast to other forensic instrumental tests. A selection of resealable bags was analysed for carbon and hydrogen isotope ratio values of bags that had been subject to various fingerprinting agents and compared to values of untreated bags. The results showed no significant difference between samples that had been fingerprinted from those that were untreated.

期刊介绍: Science & Justice provides a forum to promote communication and publication of original articles, reviews and correspondence on subjects that spark debates within the Forensic Science Community and the criminal justice sector. The journal provides a medium whereby all aspects of applying science to legal proceedings can be debated and progressed. Science & Justice is published six times a year, and will be of interest primarily to practising forensic scientists and their colleagues in related fields. It is chiefly concerned with the publication of formal scientific papers, in keeping with its international learned status, but will not accept any article describing experimentation on animals which does not meet strict ethical standards. Promote communication and informed debate within the Forensic Science Community and the criminal justice sector. To promote the publication of learned and original research findings from all areas of the forensic sciences and by so doing to advance the profession. To promote the publication of case based material by way of case reviews. To promote the publication of conference proceedings which are of interest to the forensic science community. To provide a medium whereby all aspects of applying science to legal proceedings can be debated and progressed. To appeal to all those with an interest in the forensic sciences.
