    • A method of emission spectrochemical analysis is provided which comprises the steps of producing a predetermined number of spark discharges between an electrode and a specimen containing an element in a first and second state. The intensity of emission of light caused by each of the spark discharges is measured and a frequency distribution of the measured intensities of emission is obtained. The distribution is separated into an area of normal distribution and an area outside the area of normal distribution, and an intensity of emission value is selected. The amount of the element in the first state is determined as a function of the selected intensity of emission multiplied by the area of normal distribution and the amount of the element in the second state is determined as a function of the selected intensity of emission multiplied by the area outside the area of normal distribution.
    • 提供了一种发射光谱化学分析方法,其包括以下步骤:在电极和含有第一和第二状态的元件的样品之间产生预定数量的火花放电。 测量由每个火花放电引起的光的发射强度,并且获得测量的发射强度的频率分布。 将分布分为正态分布区域和正态分布区域外的区域,并选择发射强度值。 第一状态下的元素的量被确定为所选择的发射强度乘以正态分布的面积的函数,并且第二状态中的元素的量被确定为所选择的发射强度乘以 正常分布区域以外的区域。

    • Apparatus for emission spectrochemical analysis wherein the sample to be analyzed is excited by repeated spark discharge to emit light, which is dispersed to produce a spectrum containing emission lines characteristic of the elements in the sample. The intensity or quantity of light of each of the emission lines of the elements to be determined and that of the corresponding one of the emission lines selected as the internal standards for the elements to be determined are measured each time a spark discharge is produced to obtain the ratio of the former intensity or quantity to the latter at each spark discharge, and the ratios resulting from a predetermined number of spark discharges are averaged for each of the elements to be determined. From the average the content of each of the elements is read on a calibration curve.
