Summary:

Clean Dry Air and Zero grade air are used for both dilution and analyzer support gas in exhaust gas analysis for emission testing. Variation in the oxygen content can make a significant impact on the accuracy of test results evaluated for Super Ultra Low Emission Vehicle (SULEV) standards."Air" is often assumed to retain a constant ratio of nitrogen and oxygen - yet typically the oxygen content is not measured on a real time continuous basis. Production, treatment and distribution methods - the compression, purification and pressure management of air, have been shown to be capable of modifying the transient oxygen concentration by more than 10%.The results of the testing performed identify the oxygen variation behavior of several components found in Zero Air systems
