13. Sampling pipe with Nafion tube

14. Nafion - The Perfect Drying Material Nafion is a copolymer of tetrafluoroethylene (Teflon®). Like Teflon, Nafion is highly resistant to chemical attack, but the presence of its exposed sulfonic acid groups confers unusual properties. Sulfonic acid has a very high water-of-hydration, absorbing 13 molecules of water for every sulfonic acid group in the polymer; consequently, Nafion absorbs 22% by weight of water. Unlike micro-porous membrane permeation, which transfers water through a relatively slow diffusion process, Nafion removes water by absorption as water- of-hydration. This absorption occurs as a First Order Kinetic reaction, so equilibrium is reached very quickly (typically with in milliseconds). Because this is a specific chemical reaction with water, gases being dried or processed are usually entirely unaffected.

30. Combined Size Distribution

31. SVC-Semi-Volatile Compounds Particles in the ambient air consist of solid and semi-volatile components. Semi-volatile compounds make up 20% to 50% of the PM2.5 Common samplers are losing semi-volatiles due to the ongoing sampling from the filter or by heating the sample probe to prevent condensation. Result: most measurements are underestimated.
