Abstract
An aerosol is produced by flowing a liquid sample through a gas-assisted nebulizer. The liquid exits from an outlet into a coaxial flow of gas. The outlet includes a sharp edge that inhibits or prevents accumulation of precipitates from the liquid, thereby reducing or eliminating clogging, which is particularly useful for a samples containing high concentrations of dissolved particles. The aerosol may be introduced into a plasma such that molecules are broken into atoms. The atomization may be followed by an analysis such as by optical emission spectrometry or mass spectrometry.
