A method for visual assessment of the performance of components in a continuous flow system.
When two reagents are mixed in a continuous flow system it is difficult to detect variations in their proportions in the individual liquid segments because such variations produce only small changes in the final colour intensity. A method is described whereby these differences in reagent proportion produce a different pH in each segment and, by the addition of an appropriate pH indicator solution, a different colour for each segment. This method may be used to demonstrate the eveness of reagent injection, reagent mixing and segment/segment interaction associated with continuous flow systems.
