To measure particulate matter in the ambient air, including the determination of the PM10 and PM2.5 fraction, the dust particles are collected on filters (sampling). By weighing (gravimetry) the filters before and after sampling, the content of the dust particles in the ambient air. Gravimetry is the standard measuring method within the European Union (see NBN EN 12341 (2023)) for determining particulate matter in the ambient air. Because this is a standard measuring method based on weight determination, there are strict requirements for the quality of the filters. For example, the tare weight of the filters must remain constant before and after sampling. In addition to determining the concentration of particulate matter in the ambient air, the chemical composition of the dust on the filters determined (chemical characterization). Both organic and inorganic analyzes are carried out. For example, for the analysis of carbon compounds, the filters may not be made of organic matter such as paper, polyurethane, Teflon or other plastics. Based on internal comparative tests and taking into account that other pollutants such as heavy metals (ZM), polyaromatic hydrocarbons (PAH), etc. are also collected on filters Only quartz filters from the PALL brand are suitable for VMM applications.
