SAMPLING
STUDIES WITH LIABILITIES
Our team is expert in the use and implementation of sensors to measure air quality. We have extensive experience in creating and managing passive sampling studies across Europe to support automated networks belonging to government networks such as municipalities and governments. Proper planning and quality control are key to successful and meaningful studies.
4sfera is an active member of CEN / TC 264 / Grup de treball 11 on ambient air quality – Diffuse samplers for the determination of gases and vapors – Requirements and test methods. In recent years, the group has been working on the development of the harmonized standard for passive sampling of NO2 at European level. (Review of the application of diffusive sampling in the European Union for the control of nitrogen dioxide in ambient air). 4sfera is currently assisting in the compilation and drafting of a standard for NH3 measurement with passive samplers.
