Chemical analyses

Chemical analyses of INDAAF rain samples, passive gases samplers and aerosols filters are performed at the chemical analysis service of the Laboratoire d’Aérologie in Toulouse (LAERO). The service leans on two main analytical poles: ionic chromatography and particulate carbon analysis and it also carries out gravimetric measurements on aerosol collection filters and pH and conductivity measurements on rainwater.

The service is also dedicated for the INDAAF measurement sites network to the preparation of collection materials (rain, aerosol filters) and passive samplers dedicated to atmospheric gases concentrations.
