Abstract The application of thermal lens spectrometry (TLS) to the determination of inorganic species is reviewed. The requirements of a chromogenic reaction to be advantageously adapted to TLS detection, and the necessary conditions for reaching very low limits of detection are discussed. Methods for the determination of metals and P, Si, S and N compounds in several samples are examined. Flow-injection and extraction methods, associated photoinduced reactions and surface phenomena, speciation and equilibrium studies are discussed. Gas phase NO 2 methods are also commented upon. Trends are given.
