Real-time measurement of metals in submicron aerosols with particle-into-liquid sampler combined with micro-discharge optical emission spectroscopyNARA Subscribed
Environmental Monitoring and Assessment · 2024 · Vol. 196 · Issue 11 · Springer
Sudatta Das; Kimmo Teinilä; Hilkka Timonen; Erkki Ikonen; Toni Laurila
The paper presents a novel technique for quantifying trace metals in aerosol samples in real time. Airborne metals were continuously collected for one week near the Baltic Sea in Finland using a particle-into-liquid sampler (PILS). The collected liquid samples were analyzed for metals using micro-discharge optical emission spectroscopy (µDOES). The micro-discharge analyzer is designed to perform real-time, on-site measurements...
