Abstract
An inexpensive ultrasonic nebulizer (USN) was developed utilizing a home hu midifier. The ultrasonic transducer was taken from a commercial USN and the power supply was from a humidifier. Sample was continuously fed into the n ebulizer and the detection limit was improved 3-20 times over a pneumatic n ebulizer. Undesirably, noise in signal was also increased several times. 0. 5 ppm of Mn was used as an internal reference and the "long-term" drift cou ld be successfully corrected. Since the noise contained high and low freque ncy components, both could be effectively removed only by the real-time cor rection method such as the Myer-Tracy method, where the reference line was simultaneously monitored with the analytical lines. The performance of USN was tested with NIST SRMs and showed good agreement with the certified valu es.
