Title The liquid barrier filter - A new concept to eliminate particulate contaminants from gases
Bibliographic information Feb. 1982, Vol.42, No.2, p.209-216. Illus. 20 ref.
Abstract A liquid barrier filter (LBF) consisting of a nylon fabric matrix and a continuous film of a non-toxic, chemically-inert, perfluorocarbon liquid was evaluated for removal of a fine grade Sephadex powder from a gas stream. The LBF allowed passage of 0-23.4 particles (95.7-100% efficiency) in tests of 5-30 minutes exposure compared to passage of 100▒29 to 790▒105 particles through the fabric filter alone. The liquid phase in the LBF remains intact and allows only diffusion transfer of the gas. The LBF principle can be developed for use in equipment to protect against highly toxic particles contained in an atmosphere and, possibly, to replace self-contained breathing apparatus.
