Few examples of trace chemical compounds collecting systems and in situ field instrumentation deployed

Atmosphere

  • Wet & dry depostion collection systems (Campbell bulk systems, Eigenbrodt precipitation collectors)
  • Gaz phase (CV-AFS Tekran 2537 + 1130/1135 coupled systems with mercury measurements, Passive Atmospheric Sampling – PAS – systems for trace metals, collection systems for emerging organic contaminants and volatile organic compounds)
  • Particulate phase / aerosols (HiVol systems – Digitel, Tisch models -, TSI CPC models, TSI DMPS/SMPS systems, HVAS model, cascade impactors)
