Quantitative determination of chlorides by molecular laser-induced breakdown spectroscopy

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

“…Dietz et al [60] quantified the Cl content, a harmful element present in cement-based materials, by calcium-monochloride (CaCl) molecular emission. The results showed an LoD = 0.075 wt.%, which was below the critical threshold of 0.2 wt.% of chlorides related to the cement in reinforced concrete.…”

“…Moreover, the influence of the sample composition was considered to evaluate how the initial bonds of Ca, F and Cl affect the final molecular emission signal, as well as to investigate the competitive process during the molecular formation in the plasma [38]. Additionally, Dietz et al [39] recently demonstrated that the ratio between CaCl and CaOH molecular emission in cements provided lower variations than the CaCl emission alone. It is considered that the molecular emission suffers more fluctuations than the elemental emission, since the molecular formation process depends strongly on the plasma physical conditions.…”

Composition analysis of ceramic raw materials using laser-induced breakdown spectroscopy and autoencoder neural network

“…LIBS is regarded as fast, green and promising emerging chemical detection technology. [3][4][5] In the elds of soil detection, 6 metallurgical analysis, 7 coal mining, 8 mineral development, [9][10][11] biomedicine 12 and many other aspects, LIBS technology has been the focus of quantitative analysis research. 13 LIBS is also widely used for the detection of material composition in deep space exploration missions.…”
