Particle-into-liquid Sampler
Metrohm’s 850 IC system and particle-into-liquid sampler tests air pollution by providing quasi-continuous measurements of inorganic compounds in ambient air. The system removes gas-phase compounds, and the remaining aerosol particles are dissolved to water via a supersaturated steam phase. The liquid sample is then transferred to the IC system for analysis. The unit provides a high temporal resolution of measurements, allowing users to record changes in the ionic composition of ambient air.
