cold vapour atomic absorption spectroscopy
|Within Vocab||BODC parameter semantic model analytical method entity descriptions|
|Definition||This is an analytical technique for volatile heavy metals such as mercury in which vaporised metal atoms in an argon carrier at room temperature are illuminated by a light source having an emission spectrum matched to the analyte of interest. The radiation absorbed by chemically unbound atoms is determined by analysing the transmitted energy relative to the incident energy at each frequency, which is proportional to the elemental concentrations.|
