fiber filters (MK360, Munktell & Filtrak Gmbh, Sweden) with a diameter of 90 mm due to their low background inorganic ions, high temperature resistance, and large spe-cific surface area. These filters also maintain stable flow at 100 L·min−1 during the sampling period. The filters were weighed before and after particle collection by elec-

The grade MK360 filters ability of catching 0.3 µm particles is better than 99.998%. Preparation of filter sets was carried out at the laboratory.

Munktells Typ 22 Av Per Thunström Det verkar vara alla BM-samla-res dröm att äga en Munktells Typ 22, eller kanske till och med den närmast mytiska Typ 30. Det är ingen överdrift att påstå att Typ 22 är den modell som genom åren innebar det största tekniklyftet för Munk-tells och BM.

Further tests showed that after a 2-minute flow, blank concentrations would decrease for QMA and Tissuquartz but not for or Munktell MK360 quartz filters (ØD90mm, Maidstone, UK) and weighed by the giant gravimetric balance method (Yang et al., 2015). Different filters were chosen depending on target analytes, e.g., the analysis of Si and water soluble inorganic ions must be performed with Teflon filters, while quartz filters should be used for OC and EC analysis. Micro-quartz filters are useful for testing hot stack gases as the quartz fibers can withstand temperatures up to 900 °C.
