Metrohm - Analysis of Aerosols - Brochure

The Particle-into-Liquid Sampler: a simple solution for the determination of ions in aerosols The combustion of fossil fuels for energy production pollutes the environment with large quantities of harmful substances in the form of gases or aerosols. These emissions cause damage, not only at their source, but also far away from it. The chemical and physical properties of the emissions from anthropogenic as well as natural sources are highly relevant to the climate and the enviMode of operation PILS puts aerosols into a supersaturated water vapor phase, where they quickly grow into droplets. These droplets are separated on the basis of their inertia and pumped on with a carrier fl uid, which contains an internal standard to allow simple quantifi cation. Air bubbles that are present are removed in a so-called debubbler, and the aqueous phase is transferred to an ion chromatograph for analysis.
