Abstract

An approach to optimized burner design for use with conventional commercial ultrasonic transducers is presented. Several burner designs are described that operate properly at very low flow rates so as to increase droplet residence time in the flame and minimize flow rate demands on the ultrasonic nebulizer. This system provides improved stability and an increase in sensitivity by atomic absorption of ten times compared with a conventional burner-pneumatic nebulizer system. The ultrasonic nebulization system is constructed for efficient introduction and changing of sample solutions.
