Vapor-generation assisted nebulization for nonmetal determination
Spectrochimica Acta Part B: Atomic Spectroscopy, 1995Abstract A new on-line vapor-generation nebulization (VGN) method is explored for non-metal detection by microwave plasma torch-mass spectrometry (MPT-MS). In the new method, a three-channel “Y” is used to introduce the sample and reactant solutions simultaneously into a nebulizer.

The split/splitless inlet system has basically the same fundamental drawbacks it had when it was introduced: poor repeatability of the injected amount of sample and discrimination of high-boiling analytes. Hot needle injection improves the repeatability of the sample transfer but suffers from in-needle discrimination. Injection with a fast autosampler,

Zirconia (ZrO2) thin films were prepared by metalorganic chemical vapor deposition (MOCVD) using ultrasonic nebulization with new source materials, Zr(OBu)4, Zr(OBu)3(acac), Zr(OBu)2(acac)2, and Zr(OBu) (acac)3. This process is a simple and economic method to prepare oxide thin films.

Abstract The novel analytical application of the combination of an inline electrothermal vaporization (ETV) and nebulization source for inductively coupled plasma mass spectrometry (ICP-MS) has been studied. Wet plasma conditions are sustained during ETV introduction by 200 mL/min gas flow through the nebulizer, which is merged with the ETV transport

Abstract The relative merits of three solid sample introduction techniques for inductively coupled plasma atomic emission spectroscopy and inductively coupled plasma mass spectrometry have been evaluated. The techniques studied were laser ablation (LA), slurry nebulization, and slurry introduction via electrothermal vaporization.

In this work, we have coated 0, 1, 3, and 5 wt% of Erbium (Er)-doped tin oxide (SnO2) films on glass using a simple nebulizer spray pyrolysis method to make an ammonia vapor sensor with remarkable sensitivity. X-ray diffraction, Atomic force microscopy, Ultraviolet–visible spectroscopy and photoluminescence methods were employed to inspect the thin ...

Abstract The analytical behaviour of an electrothermal vaporization (ETV) device for the introduction of mineral acid solutions in inductively coupled plasma mass spectrometry (ICP-MS) was evaluated. Water, nitric acid, hydrochloric acid, perchloric acid and sulphuric acid in concentrations within the 0.05–1.0 mol l −1 range were studied.

A study of the determination of inorganic and organic sulfur in aqueous solutions using a kilowatt-plus helium microwave-induced plasma is presented. For sample introduction, both ultrasonic nebulization (USN) and electrothermal vaporization (ETV) were investigated.
