Most multi-element lamps combine a handful of elements, e. Fluorine: Chemistry, Analysis, Function and Effects. In other projects Wikimedia Commons. In CS AAS, in contrast, a single lamp, emitting a continuum spectrum over the entire spectral range of interest is used for all elements. Multi element lamps produce slightly less sensitivity than single element lamps and the combinations of elements have to be selected carefully to avoid spectral interferences. This is the oldest and still most commonly used technique, particularly for flame AAS. Encyclopedia of Australian Science. Each of these stages includes the risk of interference in case the degree of phase transfer is different for the analyte in the calibration standard and in the sample.
