摘要
此次实验是为犯罪案件侦查等公安工作提供一种对EPS泡沫塑料快速、无损的检验方法。利用傅里叶红外光谱仪,采用Smart Performer采样器,对30个不同厂家以及同一厂家不同用途的EPS泡沫塑料样本进行分析检验。依据红外光谱图中吸收峰的不同,可以将EPS泡沫塑料样本加以区分。该检验方法操作简便快捷,结果准确可靠且无损检材,可用于公安基层实际办案。
The experiment is to provide a quick and nondestructive testing method about expandable polystyrene foamed plastics EPS for the public security work in criminal investigation.Fourier transform infrared spectroscopy and Smart Performance sampling were used to examine and analyze the 30 kinds of EPS made from different manufacturers and from the same factory.According to different absorption peaks of infrared spectra,EPS foamed plastics samples can be distinguished.This method is simple,rapid,accurate and reliable,which can be used in the actual investigation of the police.
