Research on air pollution requires rapid and accurate measurements of inorganic species in ambient air. Coupling a Particle-Into-Liquid-Sampler (PILS) to Metrohm’s 850 Professional IC allows for quasi-continuous

measurements with an unprecedented temporal resolution of just 5 to 15 minutes. In contrast to sampling devices relying on filters, using a PILS allows semi-continuous sampling of aerosols downstream from a denuder system. Subsequent to the removal of interfering gas-phase species, the remaining aerosol particles are dissolved into water phase by means of supersaturated steam. Eventually, the liquid sample is transported to the IC for analysis. Metrohm.
