LIBS coupled with ICP/OES for the spectral analysis of betel leaves

Spectral analysis of mint (pudina) using laser-induced breakdown spectroscopy and inductively coupled plasma/atomic emission spectroscopy

“…Previous findings confirm that this approach gives good results in the analysis of various soil samples to estimate the elemental contents [7][8][9][10]. Meaningful work on the quantitative investigation of various samples, namely shilajit, clays, alloys, plant materials, and the classification of tea and quartz samples have been successfully documented by this technique [11][12][13]. Most recently, LIBS was effectively engaged in the determination of xenobiotic silver in monosodium glutamate [14].…”

Catching up on calibration-free LIBS

“…In 2017 Ahmed et al 108 investigated the composition of different cigarette brands using CF-LIBS. Other papers have dealt with the CF-LIBS analysis of edible plants (see Rehan et al 109,110 in 2018 and Jabbar et al 111 in 2019). Jabbar et al 112 also characterized inorganic nutrients in maize samples.…”

Quantitative analysis of saindha salt using laser induced breakdown spectroscopy and cross-validation with ICP-MS

“…The neutral Ca line at 422.67 nm was selected for the determination of electron number density. Several studies report the electron number density, extracted using this emission line of calcium [42][43][44][45]. The self-absorption effect can influence the accuracy of results.…”
