title: Simplified description of adsorption breakthrough curves in air cleaning and sampling devices.
abstract: Breakthrough curves of organic vapors through a charcoal bed are analyzed by a simplified Theory of Statistical Moments. It is shown that this theory adequately describes the dependence of the shape of the breakthrough curve on concentration of vapor, velocity of air, particle size of charcoal, and length of the bed.
