ジャーナル フリーStainless steel is quantometrically analysed by a large spectrometer fitted with a grating of high dispersion.The spectrometer is of the largest type used in quantometers;its dispersion is 3.3A/mm (1st order), yet there was some difficulty in selecting spectral lines.Feussner's spark is used for excitation with a plane-finished sample as the upper electrode and a tungsten rod as the counter electrode.12000 volts as the secondary voltage, 0.0033 micro farads as the capacitance, 20 seconds as the pre-spark time and only the residual inductance were for obtaining suitable excitation.
Results are in agreement with those of chemical analysis with errors of less than 1% for Ni and Cr and less than 2% for Si, Mn, Cu and Mo.
As the analysis on different kinds of stainless steel is influenced by coexisting elements, parallel working curves are prepared by using standardized samples. The error caused by variation of Fe content is corrected by multiplying set values by a coefficient.抄録全体を表示PDF形式でダウンロード (1439K) -

ジャーナル フリーThis method is devised for the determination of hafnium in zirconium oxide as reactor material.The“sifter electrode-spark excitation technique ” employed by C.Feldman and J.Y.Ellenburg is utilized and the sensitivity is extended to 100 ppm hafnium.
In this technique, samples, finely ground and mixed with equal amount of graphite powder, are put into the “ sifter electrode ” used as the upper electrode, and are excited in ARL Multisoure oscillating spark.
A marked improvement is made in signal to noise ratio of hafnium spectral line but the sensitivity is not sufficient.抄録全体を表示PDF形式でダウンロード (805K)
