文章介绍了石油产品中元素的不同前处理过程和仪器测试方法,从测试速度,检测限、影响因素等进行了比较分析。结果表明,有机直接进样方式具有耗时短、污染小、损失小,操作简单等优势,有着广阔的发展前景。多元素同时分析是仪器发展的方向。目前,ICP分析技术是最成熟的,并广泛应用于元素分析。
This paper introduces different pretreatment processes and instrument testing methods of elements in petroleum products, and compares and analyzes the testing speed, detection limit, influencing factors and so on. The results show that the direct injection method has the advantages of short time-consuming, less pollution, less loss, simple operation and so on. It has broad prospects for development. Multi-element simultaneous analysis is the direction of instrument development. At present, ICP analysis technology is the most mature and widely used in elemental analysis.
