The filters collected from the various samplers will be used in a variety of analysis to characterize numerous aspects of the chemical composition and properties of the aerosols. LAPI is equipped with the necessary instruments for filter analysis e.g.:

  • Elemental and organic carbon (EC/OC)
  • Analysis for main ions and cations for hygroscopicity and pH calculations and inorganic nutrients
  • Metal Analysis
  • Offline AMS for PMF source apportionment and OC composition
  • ATR-FTIR analysis for Organic Carbon Analysis
  • Primary sugars (glucose, fructose, sucrose, mannitol, arabitol) and anhydrosugars (e.g., levoglucosan, galactosan, and mannosan)
  • DNA extraction for qPCR and metagenomic analysis
  • Lipidomics
