HIGH TEMPERATURE GAS KINETIC STUDY OF NITROUS OXIDE DECOMPOSITION PERFORMED WITH A SHOCK TUBE AND QUADRUPOLE MASS-FILTER
Abstract
A quadrupole mass-filter was built and coupled to a shock tube in order to study high temperature gas kinetics. The chemical kinetics of the decomposition of nitrous oxide was studied with this apparatus in order to establish the mechanism of the reaction at temperatures above 1000K. Several instrumentation problems unique to shock tube mass-spectrometry were solved. The most serious problem, that of a rapid-pumping ion source, was overcome by the design and construction of an unusually thin ion source. The thermal decomposition of nitrous oxide was studied by shock-heating a mixture of 4% N2O in argon and monitoring the ion currents corresponding to all of the principal species involved in the reaction: N2O, N2, O2, NO, and O. In each run with the shock tube, the mass-filter was tuned to follow the concentration of a single species. Because enough runs were made with all of the species, a run for each species at the same temperature was made for several temperatures.
