Influence of particle size distribution on the analysis of pellets of plant materials by laser-induced breakdown spectroscopy

Comparison of Fused Glass Beads and Pressed Powder Pellets for the Quantitative Measurement of Al, Fe, Si and Ti in Bauxite by Laser‐Induced Breakdown Spectroscopy

“…Most of these materials are also not homogeneous, for the sample mass size commonly used in LIBS (Zeisler ), and the small mass of the test portion may not represent the bulk sample composition, affecting both the precision of the measurements and the accuracy (de Carvalho et al . ), which may also be affected by particle size.…”

“…Although there are more than 16000 commercially available CRMs, finding a reference material with the same matrix containing different mass fractions of the same analyte is not an easy task (Silvestre et al 2015). Most of these materials are also not homogeneous, for the sample mass size commonly used in LIBS (Zeisler 1998), and the small mass of the test portion may not represent the bulk sample composition, affecting both the precision of the measurements and the accuracy (de Carvalho et al 2015), which may also be affected by particle size.…”

Direct determination of mineral nutrients in soybean leaves under vivo conditions by portable X‐ray fluorescence spectroscopy

“…Laser‐induced breakdown spectroscopy (LIBS) is another complementary tool that presents promising features aiming at the direct analysis of solid samples. It is fast, multielemental, allows simultaneous determinations, and the instruments are also available as portable devices …”

Effects of sample pretreatment and particle size on the determination of nitrogen in soil by portable LIBS and potential use on robotic-borne remote Martian and agricultural soil analysis systems

“…This is challenging because, as mentioned above 8 the quality of LIBS results obtained is enormously inuenced by the chemical and physical properties of the sample, which in turn depend on how the sample was pretreated prior to analysis. [33][34][35][36][37][38][39][40] Various methods of soil sample preparation have been developed to achieve the homogeneity required for LIBS analysis, including mechanical pressure, 41 grinding and sieving 42 and a combination of these. 39,[43][44][45] However, these potentially may be difficult to replicate in a eld setting, especially using an autonomous rover analytical platform.…”
