“…Plasma evolution was investigated by Fu et al 108 using three fast-imaging cameras that captured three successive plasma images from the same laser-induced Ti-alloy plasma. The early plasma evolution stage, when the plasma and surrounding gases have a strong interaction, was investigated.…”
This review covers advances in atomic spectrometric techniques, including atomic emission, absorption, fluorescence and mass spectrometry. Material on speciation and coupled techniques is not covered as this is included in a separate ASU review.

“…4–9 However, the subtle fluctuations of laser energy, surrounding ambiance, and sample morphology would lead to unstable plasma, causing large spectral signal fluctuations in LIBS measurement. 10,11 The large spectral fluctuations bring about large errors in LIBS analysis, impeding the improvement of precision and accuracy and hence limiting its large-scale application and commercialization. Therefore, the improvement of spectral signal stability has great significance.…”
Large spectral fluctuations bring large errors in laser-induced breakdown spectroscopy (LIBS) analysis, which impedes the improvement of precision and accuracy, limiting the large-scale application and commercialization. In this work, we...
“…2 However, LIBS was still limited by its relatively low quantitative performance due to the difficulties in modelling the complex relationship between spectral intensities and the element concentration caused by matrix effects and high signal uncertainty. [3][4][5][6] How to efficiently handle the complex relationship has become a non-trivial task to improve the capacity of LIBS quantitative analysis.…”
Laser-induced breakdown spectroscopy (LIBS) combined with machine learning has demonstrated great capabilities for quantitative elemental analysis. When the distributions of training and test data differ due to changes in measurement...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
