Characterization of primary and tertiary aerosols produced for high-temperature plasma spectrometry
- George Washington Univ., Washington, DC (United States). Dept. of Chemistry
Laser light scattering interferometry and laser Fraunhofer diffraction are used for the diagnostic studies of aerosols produced by a simple, high-efficiency pneumatic nebulizer. The new device, utilized in plasma spectrochemical analysis, operates more efficiently at low solution uptake rate (down to 10 {micro}L/min) compared to the conventional nebulizers consuming 1--2 mL/min. The efficacy of the cited techniques for assessing droplet-size information is contrasted for test aerosols prior introduction into high-temperature plasmas. Both the primary and tertiary aerosols are probed at uptake rate ranging from 10 to 1,200 {micro}L/min. The relevance of these measurements and data in elemental analysis is discussed.
