The feasibility of using metal oxide cloths as atomization surfaces In furnace atomic absorption spectrometry was studied. Y203 cloths were Introduced Into a preheated graphite furnace on a probe attached to the autosampler arm. This permitted evaluation of the new surfaces with little system modification. Data on temperature dependence and sensitivity for Ag, Se, Cd, and Pb were obtained. With Pb as the analyte, studies on precision and interferences were performed and compared to data obtained by using a conventional furnace program and graphite platform atomization.
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.
