Laser techniques for chemical analysis

Abstract

In this review a wide range of laser-based techniques for chemical analysis is discussed with reference to the principles and practical utilities of each technique. Thus techniques for atomic spectrometry, elemental analysis, molecular spectrometry, LIDAR, photothermal spectrometry and mass spectrometry are considered. Where possible qualitative comparisons are made with alternatives for particular analyses, e.g. atomic absorption and emission spectrometry. Where alternatives do not exist e.g. LIDAR, the practical utility and applications of such techniques are discussed.
