To study the influence of the electrode temperature on the intensity of the spectral lines produced by a low voltage condenser spark discharge, the temperature of the sample electrode is measured by using a thermo couple thermometer. Though the temperature of a small sample rises rapidly with the time of sparking, it is at the highest up to about 80°C under the ordinary analytical condition and so the thermal effect is thought to be negligible.High temperature such as 200°C is, however, observed after sparking for a minute under the following condition;R=1Ω, C=60μF, L=-375μH, E=600volt. According to the experimental result for the effect of heating temperature before sparking, the thermal effect appears for iron samples at temperatures above 200°C.Therefore, it is thought that the influence of temperature rise should be taken into consideration only under such a particular discharge condition as an extremely small sample is employed.
