Shock tube method for fast reaction

WebThe methods used to overcome these difficulties fall into two classes: flow methods and pulse and probe methods. In flow methods, two gases or solutions are introduced rapidly into a mixing vessel, and the resulting mixture then flows rapidly along a tube. Concentrations of reactants or products may then be measured—for example, by ... WebThe stopped-flow method is a development of the continuous-flow method used by Hamilton Hartridge and Francis Roughton [7] to study the binding of O 2 to hemoglobin. In the absence of any stopping system the reaction mixture passed to a long tube past an observation system (consisting in 1923 of a simple colorimeter) to waste.
