Liquid sample introduction system and method, for analytical plasma spectrometer

A liquid sample introduction system for a plasma spectrometer includes a sample container for holding a liquid sample, a surface acoustic wave (SAW) nebulizer, arranged to receive a liquid sample from the sample container, an electronic controller for supplying electrical power to the SAW nebulizer so as to produce a surface acoustic wave on a surface of the SAW nebulizer, for generating an aerosol from the supplied sample liquid, and an aerosol transport arrangement for receiving the aerosol from the SAW nebulizer and carrying it into a plasma or flame of a spectrometer. The electronic controller is further configured to control the electrical power to the SAW nebulizer so as to permit adjustment of the aerosol parameters, and to control the aerosol transport arrangement so as to permit adjustment of the aerosol delivery into the plasma or flame of the spectrometer.
