Recent progress on the application of LIBS for metallurgical online analysis in China

Abstract

Recent progress on the application of laser-induced breakdown spectroscopy (LIBS) for metallurgical analysis particularly achieved by Chinese research community is briefly reviewed in this article. The content is mainly focused on the progress in experimental research and calibration methods toward LIBS applications for metallurgical online analysis over the past few years. Different experiment setups such as single-pulse and double-pulses LIBS schematics are introduced. Various calibration methods for different metallic samples are presented. Quantitative results reported in the literature and obtained in the analysis of various samples with different calibration methods are summarized. At the last section of this article, the difficulties of LIBS application for molten metal analysis in a furnace are discussed.Keywords laser-induced breakdown spectroscopy (LIBS), metallurgical analysis, molten metal, calibration methods 52.90.+z PACS numbers

Application of Molecular Emissions in Laser-Induced Breakdown Spectroscopy: A Review

“…Laser-induced breakdown spectroscopy (LIBS) is an ideal spectroscopic technique for material component analysis. The advantages of a rapid, in situ, real-time and remote analysis, and simple sample preparation [1][2][3] extend LIBS to detection in various environments, such as the space [4,5], ocean [6,7], nuclear reactors [8,9], mines [10,11], and in the metallurgical [12,13] and industrial fields [14,15]. These studies are based on the atomic emissions in the spectra.…”

Laser-Induced Breakdown Spectroscopy (LIBS) For The Characterization Of Methane-Air Laminar Diffusion Flame

“…Laser-induced breakdown spectroscopy (LIBS) is a newly emerging optical detection method with the advantages of rapid, simultaneous monitoring of multi-elements, high temporal and spatial resolution, etc., and has been applied in a wide variety of fields, such as biomedicine, [12][13][14][15] cultural heritage and archaeology, [16][17][18] metallurgical analysis, [19][20][21] agricultural materials, [22][23][24][25] and so on. Recently, it has also been used for combustion diagnosis, including solid fuel combustion [26][27][28] and gas fuel combustion.…”

Applications of laser-induced breakdown spectroscopy in the aluminum electrolysis industry

“…In the metallurgical industry, LIBS can be used for in situ monitoring of melt compositions during production, which is one of the most interesting and promising areas in LIBS research [8,9]. The first reported experiment using LIBS on molten metal was performed by Runge et al in 1966 [10].…”
