Breaking the boundaries in spectrometry. Molecular analysis with atomic spectrometric techniques
Description
Since the development of atomic spectrometry, trace element and isotopic analysis has
been mainly based on the monitoring of atomic spectra and monoionic species.
However, according to the literature and considering the current instrumental
developments, it seems that some of the remaining challenges in this field can be
mitigated via the measurement of molecular spectra or of polyatomic ions. This review
discusses recent advances in three of the most important atomic techniques (laser-
induced breakdown spectrometry, high-resolution continuum source atomic absorption
spectrometry and inductively coupled plasma mass spectrometry) and how the
monitoring of such molecules or polyatomic ions containing the target analyte
enables attaining better selectivity and opens new ways to determine non-metals and
to obtain isotopic information.
