In continuous flow analysis (CFA), a sample is injected into a flowing carrier solution passing rapidly through small-bore tubing. The sample is mixed with a reagent, which reacts with the sample to develop a colour and determine the sample concentration. The use of carefully controlled flow conditions ensures that the colour development reaction is reproducible, so that the colour measurement need not wait until the reaction has gone to completion.
