GB/T 13747.9-2022 Methods for chemical analysis of zirconium and zirconium alloys—Part 9:Determination of magnesium content—Flame atomic absorption spectrometry and inductively coupled plasma atomic emission spectromet (English Version)
This document specifies flame atomic absorption spectrometry and inductively coupled plasma atomic emission spectrometry for the determination of magnesium content in zirconium and zirconium alloys. This document is applicable to the determination of magnesium content in zirconium sponge, zirconium and zirconium alloys. Method 1 is applicable to the determination range of magnesium content from 0.001% to 0.010%; method 2 is applicable to the determination range of magnesium content from 0.001% to 0.100%. Method two is the arbitration analysis method.
