  • Determining effluent concentration profiles and service lives of air purifying respirator cartridges
    Patent number: 8328903
    Abstract: A method for determining at least one of an effluent concentration profile, a breakthrough time and a filter cartridge recommendation includes receiving at least one input parameter, determining at least one of the effluent concentration profile, the breakthrough time and the filter cartridge recommendation based on the input parameter, and graphically displaying at least one of the effluent concentration profile, the breakthrough time, and the filter cartridge recommendation. The effluent concentration profile includes a plot of a concentration of a chemical species over a period of time. The breakthrough time includes a time at which a predetermined concentration of the chemical species passes through a filter cartridge.
