Ultrasonic sprayer of liquid samples for atomic-emission microwave plasma analyzer

摘要

The design of an ultrasonic sprayer of aviation oils is proposed and its performance is investigated.Theoretical and experimental studies have been conducted to study the response of the spray tube when exposed to ultrasonic vibrations.Its resonance lengths are determined for given frequencies of ultrasonic vibrations.The aerosol flow parameters are estimated (length,flow diameter,droplet size),and the coefficient for the entry of particles of the analyzed metallic impurity in the sprayed liquid into the plasma is estimated.
