Investigation of Transport Efficiency of Pneumatic Nebulization for Dissolved Solids in Flame and Furnace Atomic Absorption Spectrometry

The use of a pneumatic nebulization with impaction bead system for sample introduction of dissolved solids in flame and furnace atomic absorption spectrometry is investigated. The distance between the aerosol emerging from the capillary tip and the impaction bead is critical for dissolved solids in terms of nebulization efficiency, imprecision, absorbance signal, and interferences. The experimental results are considered to be dependent on the particle size generated by the pneumatic nebulization with impaction bead system.
