Abstract
Particles of a flow of aerosol are collected and analyzed by passing them through a housing having an inlet area, an outlet area, and a collection and analysis area. A collection electrode has a tip disposed in the flow path in the collection and analysis area. Particles are collected on the tip of the collection electrode. A microwave pulse is applied to the collection and analysis area such that a plasma is created. Atomic emissions produced during at least part of the microwave step are collected for analysis of the ablated particles.
