Continuous-flow method with integrating observation

Continuous-flow method with integrating observation, 40 262... 

In a modification of the continuous-flow method known as continuous-flow method with integrating observation (CFMIO) [3] the mixer is incorporated into the observation tube and the reaction is monitored along the flow path rather than perpendicular to it. In this mode, the observation begins immediately after the reactants enter the mixing/observation tube this dramatically extends the upper limit of the rate constants than can be measured. Also, the signal is improved by the increased path length. 

All rate constants reported in this article were measured using the continuous flow method with integrating observation (5). The complexes used were prepared according to literature cited elsewhere (6). HCIO, H SO, HCl and all alkali chlorides were p. a. or suprapure and purchased from Merck AG. Only tripl distilled water from a quartz apparatus was used to prepare the solutions. Only reactant concentrations smaller than 10 used. 

In some apparatuses, very similar to stopped-flow the flow of reactants is continuous (continuous flow methods). The observation of the reaction is integrated. An apparatus based on this principle has been described that allows the study of systems with half-time of reaction as short as 5 )xs. ...
