In the emission spectrochemical analysis, the influence of pores in sample electrodes, such as porous sintering products, powder-pressed samples, dipped electrodes etc., on the intensity and the intensity ratio of spectral-lines has been studied with samples prepared by powder metallurgy. The results obtained are as follows: (1) The intensities, intensity ratios and erosion amounts depend on the distribution, shape and amount of pores, and segregation of elements; (2) Types of the effects of the pore on the intensity differ with the amount of pore ; (3) Little influence of the pore on the intensity is observed in a range of a little amount of pore ; and (4) linear working curves are obtained with sample prepared under the fixed conditions of the forming pressure, sintering temperature, sintering time and so on.
