Abstract In this article, we present a novel method for the elemental analysis of airborne aerosol particles using electrodynamic balance (EDB) trapping followed by laser-induced breakdown spectroscopy. The setup consists of a newly designed corona-based aerosol charger, double-ring electrodynamic balance trap and optical arrangement for the spectroscopy. Experimental laboratory measurements using the method show that the minimum particle size for successful analysis is 1 µm in diameter, and the minimum airborne concentration is of the order of 1 particle/cm3. In addition to the method, we will present results on the charging efficiency of the developed charger and novel stability analysis of the EDB at the charge region. The results from the stability analysis will ease the way toward analyzing submicron particles with the technique.

使用电动平衡和激光诱导击穿光谱对环境单粒子进行元素分析

摘要 在本文中，我们提出了一种使用电动平衡 (EDB) 捕获和激光诱导击穿光谱对空气中的气溶胶粒子进行元素分析的新方法。该装置由新设计的基于电晕的气溶胶充电器、双环电动平衡阱和光谱光学装置组成。使用该方法的实验实验室测量表明，成功分析的最小粒径为直径 1 µm，最小空气中浓度为 1 个粒子/cm3 的数量级。除了该方法之外，我们还将展示所开发充电器的充电效率结果以及充电区域 EDB 的新颖稳定性分析。稳定性分析的结果将简化使用该技术分析亚微米颗粒的方法。
