Determination of Non-Metals by Molecular Absorption: A Minireview from the Beginning through Recent Developments in High-Resolution Continuum Source Molecular Absorption Spectrometry (HR-CS MAS)

Abstract

The determination of nonmetals via molecular absorption spectrometry (MAS) began in the 1970s using conventional atomic absorption spectrometry with a line source. However, due to low resolution and spectral interferences, these measurements were improved by the development of the high-resolution continuum source that provides information about the spectral environment. Hence, here is reviewed formative studies on the determination of nonmetals as well as the state of the art of this approach. This review presents the fundamentals of the MAS involving the determination of S, P, Cl, F, and Br, and the cutting-edge research such as isotopic determination via MAS.

Keywords:

• High-resolution continuum source molecular absorption spectrometry (HR-CS MAS)
