Method of Measuring the Mass Fraction of Selenium in Heat-Resistant Nickel Alloys

The central analytical laboratory at the ChMK has developed a method of measuring mass fractions of selenium based on atomic-emission and mass-spectrometric analyses. The method is very accurate in measuring low contents of selenium in heat-resistant nickel alloys. The procedure developed for mass-spectrometric analysis of mass fractions of selenium has halved the length of time needed to obtain the analytical results and made the measurement process less labor-intensive.
