Comparison of Mg/Ca concentration series from Patella depressa limpet shells using CF-LIBS and LA-ICP-MS

Catching up on calibration-free LIBS

“…Shells are of paramount importance as climate proxies. In a paleoclimate study, Garcia-Escárzaga et al 69 and Martinez-Minchero et al 70 measured Mg/Ca ratios in Patella depressa shells and found a correlation with sea surface temperature (SST), thus highlighting the potential of CF-LIBS in paleoclimatology and archaeology.…”

Effect of matrix temperature on the LIBS signal of Au

“…The main advantages of the LIBS technique over other spectroscopic techniques and specialized equipment in the geological eld are low cost, easy maintenance, no need to prepare samples in advance, and the possibility of simultaneous detection of multiple elements. 6,7 These advantages are widely used in various elds such as geological exploration, [8][9][10][11][12] metallurgical analysis, [13][14][15][16][17] marine exploration, [18][19][20][21] cultural relic identication, [22][23][24][25] environmental testing, [26][27][28][29] and nuclear material detection. [30][31][32][33] Harmon et al 34 summarised recent applications and analyses of LIBS technology in areas related to geological and environmental materials.…”
