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 ...

J. Anal. At. Spectrom., 1997
A preliminary study of a cold vapor generation system as the sample introduction device for liquid chromatography–inductively coupled plasma mass spectrometry (LC–ICP-MS) is described. Samples containing ionic mercury compounds were subjected to chromatographic separation before injection into the cold vapor generator.

Mercury (Hg) isotopic analysis via multi-collector inductively coupled plasma (ICP)-mass spectrometry (MC-ICP-MS) can provide relevant biogeochemical information by revealing sources, pathways, and sinks of this highly toxic metal. In this work, the capabilities and limitations of two different sample introduction systems, based on pneumatic ...

ABSTRACT A novel synergic effect of ultrasonic nebulization (USN) and a multimode sample introduction system (MSIS) when used in combination has been exploited for efficient generation of conventional hydride-forming (As, Bi, Ge, Sb, Se, Sn), Hg vapor, and non-hydride-forming (Ba, Ca, Li, Mg, Sr) elements. The ultrasonic nebulizer supplied a microliter
