Summary: A new and accurate method was developed to determine the dissolved concentrations of Ga in natural waters. Chelex-100, Nobias Chelate PA-1, and Presep((R)) PolyChelate resins were compared for Ga extraction from river water and seawater. Presep((R)) PolyChelate resins were chosen for analysis due to their wide extraction range at low pHs. The optimal isotope dilution conditions for Ga concentration measurements in natural water were discussed.

Summary: This study investigates the interplay between d-block metal ions and their associated biomolecules in response to invading pathogens. By using elemental techniques, the researchers were able to quantify both the distribution of trace elements and the abundance of specific transport proteins. The findings demonstrate the potential of a single instrumental platform for multiplex analyses, which can be applied to investigate complex elemental interactions and aid in the development of new therapeutic approaches.

Summary: This study developed a method for monitoring 99Tc in solid environmental samples. The use of alkali fusion instead of acid digestion ensured minimal loss of Tc during sample preparation. A simple separation method using TRU resin in alkaline solution was established, and water was used for elution and direct measurement of Tc. The method achieved high chemical recoveries and demonstrated fast and efficient analysis.

Summary: To meet the demand for multi-element/isotope analysis at the single nanoparticle (NP) or cell level, different types of inductively coupled plasma mass spectroscopy (ICP-MS) have been used to simultaneously monitor multiple mass-to-charge ratios in single-particle/cell ICP-MS (SP/SC-ICP-MS) analysis. Systematic evaluation and comparison of the performance of these techniques are urgently required.

Summary: A new strategy using N2O as a reaction gas for the simultaneous determination of nonmetallic impurity elements in high-purity magnesium alloys by ICP-MS/MS was proposed. Through O-atom and N-atom transfer reactions, spectral interferences were eliminated and higher sensitivity and lower LODs were achieved compared to other reaction modes. The accuracy of the method was evaluated and it showed consistent results with SF-ICP-MS. This study provides a systematic method for precise quantification of impurity elements and can be applied to other fields.

Summary: The Hg isotopic composition in spruce shoots mainly consists of gaseous element mercury (GEM) uptake, showing slight changes over a study period of more than 30 years despite a significant decrease in Hg concentration. Mass-dependent fractionation and odd mass-independent isotopic fractionation exhibited slight variations with time.

Summary: This paper presents a methodology based on isotope dilution for the mass determination and sizing of silver nanoparticles using single-particle ICP-TOFMS. The proposed method measures NP isotope ratios in a particle-to-particle approach, allowing for the characterization of NP mass and size distributions. The method optimization for precision and accuracy included the selection of spike isotopic composition and concentration.

Summary: This paper presents the spatio-temporal dynamics of a Grimm-type microsecond pulsed glow discharge (mu PGD) in argon at 6 mbar. The occurrence of a high current peak during the discharge ignition is analyzed and the importance of displacement current is emphasized. The development of electron excitation temperature for argon atoms and ions at various distances from the cathode is measured. The spatio-temporal evolution of selected spectral lines of argon and copper atoms and ions is analyzed during different phases of the discharge. The results suggest that the behavior of spectral line emissions differs between the pre-peak and afterglow periods, with different lines reaching maximum intensity during these phases. The appearance time and decay time of the afterpeak are shorter for ions than for atoms. These findings are explained in terms of three-body recombination processes and ion mobilities.

Summary: In this paper, the combination of Tesla coil discharge (TCD) and laser-induced breakdown spectroscopy (LIBS) was used to enhance the emission of Al atomic lines and AlO molecular bands. The optimized distance between the TCD tip and the sample surface was found to be 5 mm, and the optimal laser energy was 25.1 mJ. Furthermore, TCD-SELIBS showed lower limits of detection (LoDs) for Cr and Pb elements compared to surface enhanced LIBS (SELIBS). The combination of TCD and LIBS is a promising technology for high-sensitivity analysis of heavy metals in water, with the advantages of simplicity, low cost, ease of operation, industrialization, and commercialization.

Summary: Titanium is an important metal widely used in various industries. Ilmenite minerals are the main source of titanium metal and can be found in igneous and metamorphic rocks as well as different types of deposits. To accurately determine U-Pb ages of ilmenite, a new calibration method and appropriate reference materials are urgently needed. Laser ablation sector field inductively coupled plasma mass spectrometry has been used to minimize matrix effects and zircon 91500 has been identified as a suitable reference material for measuring the Pb/U ratio in ilmenite. The direct calibration method using zircon 91500 as an external standard has been found to be effective for in situ U-Pb dating of ilmenite samples under different ablation settings.
