Thin Solid Films, 2013
Abstract ZnO thin films were deposited on soda lime glass substrates at 275 °C by metal-organic chemical vapor deposition using ultrasonic nebulization and the dependence of their microstructures and properties on film thickness were investigated. Deposition rate was controlled by mass transfer rate at flow rates lower than 6 l/min and by surface ...

Journal of Analytical Atomic Spectrometry, 2005
A Y-shaped Teflon connector was designed to branch the capillary of a conventional commercial flame atomic absorption spectrometer for the introduction of inorganic Hg2+ aqueous solution and KBH4 solution. The two solutions were merged inside the connector before being nebulized into an aerosol by air in the nebulizer of the instrument, and the atomic ...

Spectrochimica Acta Part B: Atomic Spectroscopy, 1998
Abstract A new method for quantification of spectral interferences based on analyte isotope ratio measurements in the presence of various concentrations of a specific matrix is presented. Within the method, a tolerance level is used, defined as the matrix concentration at which the ratio between analyte isotopes with and without interferences is ...
