Wet-strengthened grades These grades contain a reinforcement agent that increases their resistance to rupture when wet, such as in vacuum filtration, and

Each set of samples was continuously collected for 48 or 24 h, depending on the Air Pollution Prediction Index provided by the local government. Routine sampling was conducted for 48 h from 10:00 (local time) on Monday to 10:00 on Wednesday every week. Intensive sampling intervals of 24 h were also performed to Munktell MK360 de 150 mm de diámetro, acondicionados durante 48 horas antes da pesada na sala de balanzas, a 20±1ºC de temperatura e 50±5% humidade relativa. Aínda que se trata da medida de PM10, o tratamento dos filtros realizouse segundo a norma UNE-EN … the use of quartz filter (Munktell MK360, 25mm) instead of the PTFE (Polytetrafluoroethylene) filters indicated by the sampling method, due to their better extractability and higher cleanliness which allowed fully benefitting of the GC/MS (Gas Chromatography- Mass Spectrometry) analytical method adopted. The … The PM2.5 samples were collected onto Whatman 3-5 Teflon membrane filters (Ø = 47 mm, Maidstone, UK) or Munktell MK360 quartz filters (Ø = 5 90 mm, Maidstone, UK) and weighed by the giant Whatman QMA, Pall Tissuquartz 2500-QAT and Munktell MK360. Three identical Derenda sequential low volume samplers were installed at the A10 Ring Zuid highway monitoring site of the Air Quality Monitoring Network of Amsterdam.

Three identical Derenda sequential low volume samplers were installed at the A10 Ring Zuid highway monitoring site of the Air Quality Monitoring Network of Amsterdam. Each sampler was loaded with 15 filters of one type, 7 of which field blanks, and was 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. Grade MK 360 100% is available for applications requiring extremely low levels of trace elements or media that can withstand temperatures between 500°C and 900°C.

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-

Available as a round filter or sheet; Temperature resistance up to max. 900 °C; Each batch is checked and certified for trace elements; Made from micro-quartz fibers of extreme purity, binder-free Whatman QMA, Pall Tissuquartz 2500-QAT and Munktell MK360.

fibre filter (15 cm, Munktell MK360, Digitel sampler, 25 m3 h−1) without an up-per cut-off. Low-pressure impactors (Berner LPI) were used obtaining day- and nighttime (12 h) samples. Polyvinylfluoride foils were used as sampling substrates for ions and mass whereas aluminium foils were useed for carbon analysis. Two

Quartz microfiber filters – binder free Ahlstrom-Munksjö offers extremely pure 100% quartz filters with temperature stability up to 900°C which makes these filters ideal for use in applications like hot stack measurements.

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.

In addition, micro-quartz is used when the highest purity media is required.

The analytical detection limits were 45 ng Pb and 3.8 ng Br (mean blank value + 3 σ). These values correspond to de-tectable levels of ca.
