Highly sensitive cf4 LeakSpy manufacturers

The speaker discussed results obtained by James Lovelock (*1919), a British scientist who had invented a highly sensitive way to measure trace gases. Lovelock had measured trichlorofluoromethane (CFC-11) in the atmosphere in amounts that suggested that practically all of the CFC-11 ever manufactured was still present in the atmosphere.

  • Tetraflouromethane, CF4 Specialty Gas | Concorde Specialty Gases

    CF4, Tetrafluoromethane, R-14 Specialty Gas. Carbon Tetrafluoromethane (CF4, R-14) is a low temperature refrigerant and is also used in a variety of wafer etch processes. Tetrafluoromethane is used with oxygen to etch polysilicon, silicon dioxide, and silicon nitride. It is relatively inert under normal conditions and is a oxygen displacer.
