This standard describes a method for the determination of a magnesium content up to 0.1% (w/w) using atomic absorption spectrometry and is applicable to the chemical examination of iron. If the requirements stated in Chapter 4 are met, the detection limit is 0.0015% (m/m) magnesium. The determination is not dis urbed by the elements normally found in iron. The interference suppressor used (strontium ions) is sufficient to suppress the interference by a maximum of 0.2% (w/w) aluminum, 5% (w/w) silicon and 1% (w/w) titanium.
