In this work, a general view of multi-commutation in flow analysis process is presented. The manuscript comprises a comprehensive description of the basic manifolds designed to demonstrate the multi-commutation concept including the operational modes and the inherent features. A multi-function flow system with the ability to carry out three-operation modes without any hardware modification is also described. Intending to demonstrate the versatility of the flow system based on multi-commutation process, a set of experiments was designed comprising an in-line dilution and stopped flow approach. Standard solutions of iron and of orthophosphate were selected as models to demonstrate the analytical potential of the proposed system. The results obtained are presented and discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
