Multiple-element analysis of coal using collinear double-pulse laser-induced breakdown spectroscopy

Abstract

Collinear double-pulse laser-induced breakdown spectroscopy has been developed to enhance the emission signal of coal plasma. The influence of the energy ratio and the inter-pulse delay time on the intensity...

Accuracy improvement of laser-induced breakdown spectroscopy coal analysis by hybrid transfer learning

“…6,7 LIBS has been applied in the eld of coal analysis due to these advantages. [8][9][10][11][12][13][14] However, LIBS typically requires collecting calibration spectra with known content and building a quantitative model to predict the content of unknown coal samples. The experimental parameters and the properties of the coal might change aer the quantitative model has been established.…”
