A Microfabricated Nebulizer for Liquid Vaporization in Chemical Analysis

Journal of Microelectromechanical Systems, 2006
A miniaturized nebulizer chip for vaporization of liquid samples for mass spectrometry has been designed, fabricated, and characterized for fluidic and thermal performance. Silicon/glass chip has a liquid sample channel placed centrally between symmetric nebulizer gas channels.

Review of Solid Sample Introduction for Plasma Spectrometry and a Comparison of Results for Laser Ablation, Electrothermal Vaporization, and Slurry Nebulization

Microchemical Journal, 1994
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.

Electrostatic Sample Nebulization for Improved Sample Vaporization in the Split/Splitless Gas Chromatography Inlet

Analytical Chemistry, 2009
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,

Electrothermal vaporization of mineral acid solutions in inductively coupled plasma mass spectrometry: comparison with sample nebulization

Spectrochimica Acta Part B: Atomic Spectroscopy, 1999
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.

Electrothermal vaporization and ultrasonic nebulization for the determination of aqueous sulfur using a kilowatt-plus helium microwave-induced plasma

Journal of Analytical Atomic Spectrometry, 1992
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.
