Multiway Calibration Strategies in Laser-Induced Breakdown Spectroscopy: A Proposal
نویسندگان
چکیده
In this study, a new approach to laser-induced breakdown spectroscopy (LIBS) data modeling using multiway algorithms was investigated. Two case studies, parallel factor analysis (PARAFAC) and unfolded-partial least-squares with residual bilinearization (U-PLS/RBL) were used in (1) the determination of Al, Cu, Fe samples reference material printed circuit board (PCB) from electronic waste (2) Ca, K, Mg human mineral supplement, where depth obtain multidimensional first delay-time second. addition, univariate calibration applied compared approaches. all cases, set prepared salts. PARAFAC showed satisfactory results low prediction errors good accuracy for most samples, U-PLS/RBL algorithm presented best performance supplement samples.

متن کاملLaser Induced Breakdown Spectroscopy
Laser-induced breakdown spectroscopy (LIBS) is a powerful analytical technique that can be used for the detection and characterization of materials. In LIBS, a focused laser beam is used to generate a plasma plume on the surface of solid and liquid samples or inside the sample volume of gases, liquids, and aerosols. Each excited atom in the plasma emits a unique set of spectral lines, particula...
