title: Some observations on the interferences in flameless atomic-absorption spectrometry of magnesium.
abstract: Interferences in flameless atomic-absorption spectrometry of magnesium were investigated by the use of a molybdenum micro-tube atomizer with a double indentation. Two atomization processes were compared in order to understand the interference mechanism: atomization from separate indentations, and mixture-atomization. Most elements tested gave no interference in atomization from separate indentations, whereas magnesium absorption was somewhat reduced in mixture-atomization. However, zinc and lead caused broadened absorption profiles in mixture-atomization. Chromium interfered in both atomization processes. The origin of these interferences is discussed.
