摘要
塑料袋是各类案件现场中常见的物证之一,研究建立一种简便快速、灵敏准确的检验黑色塑料袋样品的方法,为侦查破案提供线索、指明方向,缩小侦查范围,为证实犯罪提供科学的依据.利用能量色散型X射线荧光光谱仪(XRF)对41个不同品牌、不同规格的黑色塑料袋样品进行测定,采用Plastic-fp软件进行数据处理,依据样品中所含元素的种类及含量的不同,可以对不同品牌不同规格的黑色塑料袋样品进行区分.该方法重现性好,且无损检材,可用于检验黑色塑料袋物证.
Black plastic bag is one of the most common and various types of evidences in crime scene.We establish a simple,rapid,sensitive and accurate method to inspect black plastic bag samples to offer clues,point out the direction and narrow the scope for investigation and to provide scientific evidences for the confirm the crime.We use energy dispersive X ray fluorescence spectrometer（XRF）to measure 41 kinds of black plastic bag samples of different brands and sizes,and use Plastic-fp software to deal with the data.Based on the type and contents of elements contained in the samples,we can distinguish different brands and different specifications of the black plastic bag samples.The method is well reproducible and nondestructive for testing materials,so it can be used to inspect black plastic bags for evidence.
