The following equation can be used to correct a measured pollutant concentration in an emitted gas (containing a measured CO content) to an equivalent pollutant concentration in an emitted gas containing a specified reference amount of CO:
As an example, a measured particulates concentration of 200 mg/m in a dry gas that has a measured 8 volume % CO is:
:200 × ( 12 ÷ 8 ) = 300 mg/m
when corrected to a dry gas having a specified reference CO content of 12 volume %.
