TL;DR: In this paper, double-pulse LIBS (DP-LIBS) is used to detect heavy metals in the soil, and the contribution of the signal enhancement by adjusting the energy ratio of the two lasers and the best interpulse time under different laser energies.

TL;DR: In this paper, the process of cemented carbides manufacturing requires rapid and field elemental analytical techniques to control and evaluate the properties of products, and this process requires a large number of field elemental tools.

TL;DR: In this article, a miniature digital delay generator was designed and built for time-resolved laser-induced breakdown spectroscopy (LIBS) with a widely adjustable time delay with 0.1 ns resolution.

TL;DR: In this paper, a waste ore sorting method and device based on the laser induced breakdown spectroscopy (LIBS) was described, which consists of an ore pulverizer, a filter, a conveying device, a sample shape inspection system, an LIBS detection system, a mechanical sorting and ore collecting system and a measurement and control system.

TL;DR: In this article, a method for plastic sample element identification based on laser-induced breakdown spectroscopy was proposed, which includes a step (1) of establishing an elemental characteristic line database based on an NIST database; step (2) performing an experiment on a plastic sample through am LIBS device to obtain a 2D data matrix; step 3 of performing baseline correction on LIBS spectra based on a discrete wavelet transform method; step 4 of spectral peak identification on the corrected spectra according to a continuous wavelet transformation method; and step 5 of comparing data in
