2021/4/29 · Air monitoring methods have been developed to detect and quantify diverse contaminants and particulates, including PM2.5, PM10, sulfur dioxide, fluorides, heavy metals, and radioactive particles. Many of these methods involve gravimetric analysis and monitoring systems that use membrane filter discs and filter holders.

Type AA (0.8 µm) and HA (0.45 µm) MF-Millipore™ membrane filters, matched in pairs to within ± 0.1 mg, are available in 37 mm (AA) and 47 mm (AA and HA) diameters. Used for gravimetric analysis of particle contamination by the matched-weight filter method, these products eliminate the need to preweigh the test filter.

Filter membranes for filtering organic solvents and aqueous solutions for HPLC and other analytical methods, and for use in sample preparation, clarification, particulate removal, sampling, filter sterilization, and separation and retentate techniques.

Membrane sheets of various material compositions and pore sizes designed for use in filtration procedures. Applications include air and fluid monitoring, bioassaying, particle identification, microscopy, etc. Designed for air monitoring, bioassays, dairy microbiology, particle monitoring and particle removal.
