Insights into the role of transition and noble metals mediating photochemical vapor generation
Stable gas production from radical precursors during UV-C photolysis provides a tool for investigating transition metal-mediated PVG reactions. A tutorial approach supporting photocatalytic interactions with generated transition metals is presented.
Laser-induced breakdown spectroscopy (LIBS): calibration challenges, combination with other techniques, and spectral analysis using data science
LIBS is a versatile analytical tool for rapid analysis. Advances in calibration, data fusion with other techniques, and machine learning are enhancing accuracy, making LIBS crucial for fields like industrial quality control and space exploration.
Automated salting-out assisted single-phase liquid–liquid extraction of Cr(VI) from river water samples prior to its atomic absorption spectrometric determination
A new automated method was developed combining the features of the salting-out effect, single-phase liquid–liquid extraction (SPLLE), and flow-batch analysis to determine Cr(VI) in river water samples by ETAAS.

Fast and high spatially resolved multielemental mapping of otoliths using IR&UV-femtosecond laser ablation-ICP-TOFMS
Fast, high-spatially resolved, multi-elemental analysis of otoliths using fs-LA-ICP-TOFMS, quantitative analysis using IR-fs-LA and UV-fs-LA, determination of major and trace analytes, MACS3 as calibrating sample.
Feasibility of laser-induced breakdown spectroscopy for determination of neodymium in magnet alloys
The quantification of rare earth elements in (Nd–Pr)–FeB alloys used in the production of super magnets is required to ensure the quality of the raw material and a final product with suitable properties.
Application of one-point calibration LIBS for quantification of analytes in samples with distinct matrix characteristics: a case study with Hg
Combining calibration-free LIBS with the one-point calibration method can mitigate matrix effects and compensate for variations in system optimization, enabling accurate Hg quantification in soil and landfill leachate samples.
Evaluation of calibration approaches for quantitative analysis of sludge by laser induced breakdown spectrometry
Sludge disposal is a serious environmental issue and its use in agriculture depends on chemical analysis.
A convective heated digestion system with closed vessels: a new digestor for elemental inorganic analysis
A CHDS with closed vessels is now available as a simple, fast and safe alternative for sample preparation for trace element determination. The analytical performance in terms of residual carbon, accuracy, precision and LODs was demonstrated.
Mercury determination in bioresorbable calcium phosphate using a new electrothermal vaporization system coupled to ICP-MS
A new ETV system coupled to ICP-MS was developed to determine Hg at the ultra-trace level in bioresorbable calcium phosphate-based ceramic materials.
