Cytiva Whatman - Model PM2.5 PTFE - Air Monitoring Membrane Filters Cytiva’s Whatman PM2.5 PTFE membrane filters are designed for PM 2.5 ambient air monitoring. These high-purity, thin filters are sequentially numbered and come with chemically resistant polypropylene support
2021/4/22 · Abstract: Atmospheric NH3 and particulate NH4+ were collected on H3PO4-impregnated Whatman 41 and PTFE filters, respectively, and the filters were extracted with water. The extracts were analyzed in a flow injection system by injecting the solution into the phthalaldehyde(I) eluent stream and measuring the fluorescence of the NH4+ - I moiety at 455 nm (excitation at 335 nm).
Applications: Chemicals, Petrochemicals, and Fertilizers Computers, Semiconductors, and Electronics Food and Beverage Glass and Glass Products Healthcare and Hospitals Metals and Metals Fabrication, Mining (Coal, Minerals, Metals) Pharmaceutical and
2017/4/24 · Ion exchange membrane (IEM) is one of the key components of VRB to prevent the crossover of vanadium ions, and allow the transport of ions to complete the conducting circuit. The ideal IEM should possess low permeation rates of vanadium ions to minimize self-discharging, high conductivity, good chemical stability and cost-competitive.
