A significant reduction in measurable absorbance is demonstrated by application of a wavelength modulation technique using diode lasers in laser atomic absorption spectrometry in graphite tube atomizers. While rubidium and lanthanum are measured by absorption of fundamental diode laser radiation at 780.03 and 670.95 nm from the ground and an excited state, respectively, aluminium is determined by deep blue light at 396.1 5 nm produced by the second harmonic generation of diode laser radiation in an LilO, crystal.
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.
