| Abstract: | This paper demonstrates the performance of a new design of atmospheric pressure flow-tube reactor coupled with an ion trap mass spectrometer. The reactor is designed for studying gas-phase reactions with reaction times in the range from 0.2 to 2 s. The system provides a simple, fast and robust method for introducing the reactant mixtures and for identifying the products of gas-phase reactions. As a practical example of application, we used the flow reactor to study the reaction of O3 with 2,3-dimethyl-2-butene. Good agreement was obtained between the flow tube results and previously reported studies for the identification of major products and measurement of their yields. This design has the potential to be used to study the atmospheric ozonolysis reactions of unsaturated species at realistic pressures and temperatures. |
