Recebido em 15/7/97; aceito em 24/3/98 A SIMPLE CELL FOR ASSEMBLING COMMERCIAL ION-SELECTIVE ELECTRODES IN CONTINUOUS FLOW ANALYZERS. A simple flow cell for potentiometric detection is described. It was assembled by making use of two perspex pieces fixed together by means of four screws, and allow the connection of plane membrane conventional electrodes to flow system. Details about its construction are presented. The device performance was evaluated by making use of a cyanide ion-selective electrode. The relative standard deviation was about 0.5% with a detection limit of 8.0 x 10-6 mol CNdm-3. Under experimental conditions, the linear range was 10-5 to10-2 mol dm-3 .
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.
