Suitable diluent air can be obtained from specialty gas suppliers, and in certain industrial settings, high-purity nitrogen is available as a plant-wide utility. Whatever the source, the diluent air must be free of detectable amounts of the target analyte, and—ideally—meet the following purified diluent air specifications:





CompoundMax. Allowable 
CO< 0.5 ppm
Particulates < 0.45 micrograms
N2< 0.5 ppm
NOx< 0.5 ppm
SO2< 0.5 ppm
 Total hydrocarbons< 0.5 ppm
