Qualitative and quantitative analysis of environmental samples by laser-induced breakdown spectrometry

The key achievements in the determination of trace amounts of components in environmental samples (soils, ores, natural waters, etc.) by laser-induced breakdown spectrometry are considered. Unique capabilities of this method make it suitable for rapid analysis of metals and alloys, glasses, polymers, objects of cultural heritage, archaeological and various environmental samples. The key advantages of the method that account for its high efficiency are demonstrated, in particular, a small amount of analyzed material, the absence of sample preparation, the possibility of local and remote analysis of either one or several elements. The use of chemometrics in laser-induced breakdown spectrometry for qualitative sample classification is described in detail. Various approaches to improving the figures of merit of quantitative analysis of environmental samples are discussed. The achieved limits of detection for most elements in geochemical samples are critically evaluated.
