Sample Temperature Effect on Steel Measurement Using SP-LIBS and Collinear Long-short DP-LIBS

Atomic spectrometry update: review of advances in the analysis of metals, chemicals and materials

“…Kashiwakura and Wagatsuma developed a method using a LIBS system made in-house followed by partial least squares regression (PLSR) for the rapid determination of components of austenitic stainless steels. 26 Eight CRMs of the JSM M 200 series (materials [21][22][23][24][25][26][27][28] were used to train the model for the analytes Cr, Mo, Nb, Ni and Ti. Spectral data could be obtained very rapidly (approx.…”

“…In a second paper by the same research group, sample temperature effects were compared for both single pulse LIBS and colinear long-short double pulse LIBS. 28 The authors used the emission intensity ratio of Mn 404.136 nm/Fe 402.187 nm and the Fe 402.187 nm/Fe 400.524 nm for the comparison. The effect of the delay time between pulses was also studied.…”

“…Silicon in petroleum products is a 'hot topic' following historic contamination issues and its presence in re-processed fuels. The only useable isotope for Si, 28 Si suffers from interferences mainly related to the polyatomic ions 12 C 16 O and 14 N 14 N. These interferences were reduced by adding hydrogen as a reactant gas in the octopole reaction cell and the optimization of the operating parameters such as carrier gas, optional gas and hydrogen gas ow rates. A test mixture of 11 Si compounds was used for this work and included cyclic and linear siloxanes, silanols and silanes.…”

Effect of Plane Mirrors Combined with Au-Nanoparticle Confinement on the Spectral Properties of Fe Plasma Induced by Laser-Induced Breakdown

“…The technology is simple in sample preparation, easy in operation, and comprehensive in elements detected. Laser-induced breakdown spectroscopy (LIBS) technology is widely used in material detection, 1 − 3 environmental monitoring, 4 − 7 gas composition analysis, 8 − 10 and other fields. 11 − 14 Traditional LIBS has the disadvantages of low detection sensitivity and high spectral line background noise.…”

“…The technology is simple in sample preparation, easy in operation, and comprehensive in elements detected. Laser-induced breakdown spectroscopy (LIBS) technology is widely used in material detection, − environmental monitoring, − gas composition analysis, − and other fields. − Traditional LIBS has the disadvantages of low detection sensitivity and high spectral line background noise. Therefore, many methods have been proposed to enhance spectral intensity and improve the sensitivity of LIBS systems, such as nanoparticle enhancement, increasing sample temperature, multipulse, and other methods.…”
