This method is for determining carbon dioxide, oxygen and carbon monoxide in flue gases. The lower limit of detection is 0.2 mol-%. If hydrogen sulfide or other acidic compounds are present, the carbon dioxide determination will require correction. This method is designed as a rapid control room test. UOP Method 539, a gas chromatographic technique, is the recommended laboratory test, provided the separation of oxygen and argon is not required.
