摘要

介绍了一种用于扫描质子微探针分析的大气气溶胶单颗粒样品的制备方法。通过实验摸索出一种适合于支撑颗粒物的材料聚乙烯醇缩丁醛（PVB）。大气颗粒物被直接采集在PVB薄膜上从而制成样品

保持了颗粒物的原始信息。用显微镜观察了采集的颗粒物

颗粒物之间完全分开

颗粒物间距合适。样品的扫描质子微探针试验结果表明

所制成的单颗粒样品能经受住质子束的长久轰击。对PVB薄膜的本底测试表明

这种膜的本底很小

不会对被测颗粒物的元素产生干扰。

Abstract

A new method for sample preparation of individual aerosol particle in SPM analysis was developed. Aerosol particles were collected directly on the polyvinyl butyral ( PVB ) foil by using air sampler. Microscopic observation indicates that the particles were separated completely and the interval of particles was reasonable. The SPM experiment proves that PVB foils have excellent stability under proton microbeam bombardment and are a suitable backing material for supporting the single particle for SPM analysis.
