摘要
目的研究激光刻蚀等离子体质谱法对打印纸品牌的区分能力。方法收集了国内20个不同品牌的打印纸,应用激光剥蚀等离子体质谱方法进行元素分析,并采用SPSS系统聚类方法对测试数据进行处理。结果依据元素响应值比值的差异将20个不同品牌的打印纸区分为12类。结论此方法可对打印纸品牌进行有效区分。
20 brands of printing paper were collected and analyzed by laser abliation—inductively coupled plasma mass spectrometry(LA-ICP-MS).The data was processed by SPSS cluster analysis.The results showed that the most brands of the printing paper can be distinguished.LA-ICP-MS is an effective means for identification of printing paper.
