摘　　要：方法:建立电感耦合等离子体质谱法和扫描电镜能谱法联用技术分析不同生产厂家的不同品牌的纸张。采用扫描电镜能谱法定性分析不同生产厂家不同品牌的纸张中无机元素,通过微波消解前处理技术和电感耦合等离子体质谱法定量分析21张书写纸中Ti、Cr、Cu、Zn、Ba、Pb、Al七种微量元素。结果表明:两种方法联用能够成功区分不同生产厂家生产的不同品牌的书写纸张。Method:Comprehensive method was put forward by combining SEM-EDS and ICP-MS,which can be used to analyze the elements in writing paper evidence.SEM-EDS was used on the qualitative analysis of the inorganic elements.It was used to analyze the trace element content(Ti,Cr,Cu,Zn,Ba,Pb and Al)by the microwave-assisted digestion and ICP-MS.Result:It was an effective method to determine the differences among the writing file paper evidence by combining SEM-EDS and ICP-MS.
