摘　　要：在低真空条件下利用扫描电子显微镜/X-射线能谱仪(SEM/EDS)对3份激光打印文字的墨粉成分进行同一性司法鉴定,并利用傅立叶变换红外光谱仪对样品进行验证性分析.发现两种检测结果一致,即SEM/EDS是司法鉴定中一种有效可行的检测激光打印文字墨粉成分的方法.To identify the laser printer toners on questioned documents for forensic identification, three pages of questioned documents were investigated by SEM/EDS under the low vacuum level condition. Fourier transformation near-infrared spectroscopy was utilized to verify the test. Compared with the result with NIR testing, the results of the two methods were basically identical. The SEM/EDS offers an effective method of identification of laser printer toners on documents.
