Abstract : This patent describes a method and device for diluting a first gas mixture having a known concentration of a given gas to obtain a second gas mixture containing a lower known concentration of the given gas. The device enables one to mix gases with appropriately low concentrations of a particular gas such that the gaseous mixture may be used to calibrate an instrument that measures such low concentrations of a gas.
