Assessment of water and ion content in particulate matter: Comparison of two methods for determining particulate mass on a filter by Kamila Widziewicz-Rzońca, Dmytro Chyzhykov, Ewelina Cieślik, Grzegorz Majewski

“…The second method involved direct gravimetric analysis, weighing successive filter subsections (each covering 1/10 of the total area) to quantify solid particles, water, and ions. Six Whatman™ quartz filters (Ø15 cm) exposed to PM1 and PM2.5 fractions were analyzed. …”
