Mn Filter Paper refers to filter paper impregnated with manganese oxide (MnO). It is designed to trap and retain fine particulate matter from air or water samples. This type of filter paper is used primarily for the collection and measurement of particulate matter, particularly in air and water quality monitoring applications. The offered paper can be used in air quality testing to measure the levels of pollutants in the air, or in water quality testing to determine the presence of specific metals or other contaminants in water samples. Mn Filter Paper can be subjected to various analytical methods, such as spectrometry, to determine the concentrations of specific compounds or elements present.
