The drop-size distribution of fogs in ultrasonic and pneumatic nebulization was determined. In the case of ultrasonic nebulization, the maximum of the drop-size distribution was at 9 microns, and in the case of pneumatic, it was at 25 microns. But in the latter case, an effective use of glass impact bead made the maximum to 10-12 microns. After the drops of solution were flowed through a 1-m long tube, e.g., an aerosol making device, the particle size was controlled by the flow speed of the gas. At a high flow speed the particle size increased, and at a low speed it decreased. No difference between the above two nebulization methods was observed in this case.<BR>These experiments were carried out for the purpose of discussing the mechanism of the introduction of solution samples into light sources. The present results may play an important role in discussing the sensitivity and reproducibility of spectrochemical analysis in the future.
