The charge exchange mass spectrum of nickel carbonyl has been reported using a typical gasoline engine exhaust gas as the reactant gas. Various positive ions which can be attributed to nickel carbonyl and its fragments were observed in this mass spectrum. The effect of pressure on the intensity of both the reactant gas ions and the nickel carbonyl was studied in an attempt to find the optimum condition for the quantification of nickel carbonyl. Using these data, the minimum detectable limit was found to be 10 ppb for nickel carbonyl. This methodology was used to monitor nickel carbonyl in the effluent from a model reactor for a catalytic controlled automobile. Based on these studies, no measureable quantities of nickel carbonyl can be expected from catalytic controlled automobiles.
