Tailored for precision-driven chemical tasks, Whatman's Qm-A Quartz Filter Circles, with a diameter of 50 mm, excel in the realm of Glass-/Quartz Fibre Filters. These filters, made from high-quality quartz microfibre, are designed to handle various applications within filtration and separation processes. They are particularly effective in air sampling for acidic gases, stacks, flues, and aerosols, even at elevated temperatures up to 500°C. Due to their low alkaline earth metal content, they minimize the formation of artifact products such as sulfates and nitrates from SO2 and NO2. This makes them an ideal choice for PM-10 testing.
