Summary: The study compared the determination characteristics of copper and manganese in seawater by high-resolution continuum-source and low-resolution line-source graphite furnace atomic absorption spectrometry. HR-CS GFAAS can determine elements in undiluted samples, while LR-LS GFAAS only allows determination at double dilution. The detection and quantification limits for manganese were significantly lower in HR-CS GFAAS.

Summary: This article presents a rapid and accurate method for determining the zinc and iron content in food using high-resolution continuum source graphite-furnace atomic absorption spectrometry. By monitoring a narrow spectral interval, both elements can be measured simultaneously in a single firing, making the analysis fast and sensitive. Analysis of a large set of vegetable samples indicates higher zinc and iron contents in homegrown vegetables compared to store-bought ones.

Summary: This study aimed to evaluate the potential of high-resolution continuum source molecular absorption spectrometry (HR-CS MAS) in determining the new element vanadium. Using VO as the target molecule, high-resolution overview spectra were obtained and analyzed in a wide range of wavelengths. A unique instrumental setup combining a prototype Modular Simultaneous Echelle Spectrograph (MOSES) and a commercial HR-CS MAS apparatus was employed. The results showed that HR-CS MAS can be used to determine vanadium in heavy petroleum oil catalysts using a flame version of the spectrometer. However, the sensitivity was relatively poor and only a small population of VO molecules could be generated in graphite furnace measurements.

Summary: A direct immersion dual-drop microextraction (DIDDME) method was developed for the separation and preconcentration of Cr(III) and Cr(VI). Using two organic drops on needle tips of microsyringes, each containing a specific chelating reagent, Cr(III) and Cr(VI) were selectively extracted into different drops. The method showed low detection limits, wide linear range, high enrichment factors, and good precision, and was successfully applied to quantify Cr(III) and Cr(VI) in food samples.

Summary: Graphite furnace atomic absorption spectrometry (GFAAS) is a highly sensitive method for determining elements in samples with low sample volume requirements. While line-source GFAAS is widely used, high-resolution continuum source (HR-CS) GFAAS allows for more accurate correction of matrix-induced spectral backgrounds. This article reviews recent innovations and developments in GFAAS, including instrumentation, characterization of fundamental properties, progress in HR-CS GFAAS, sample preparation procedures, elemental speciation, preconcentration/separation protocols, and direct analysis.

Summary: A novel liquid phase microextraction method was developed for the simultaneous determination of lead and cadmium in different samples. The method utilized effervescent tablets to improve extraction efficiency, achieving good linear calibration range from 0.06 to 10.0 mg L-1 (Pb) and 0.02 to 1.50 mg L-1 (Cd). The study demonstrated that the proposed method is applicable for accurate determination of lead and cadmium in water and canned food samples.

Summary: This paper proposes a novel approach using internal standards and bandpass mode in single particle ICP-MS for the characterization of Au nanoparticles in complex matrices. The method was validated for different matrices and the sensitivity of the nanoparticles was affected by matrix effects. Two methods, particle size method and dynamic mass flow method, were used to determine the transport efficiency and achieve accurate results. The use of bandpass mode provided flexibility in tuning the sensitivity for each nanoparticle type to ensure accurate characterization.

Summary: After 40 years of development, ICP-MS is no longer considered a new technique. It has become the standard for multi-element bulk analysis and isotope ratio determination. In recent years, it has also shown potential in individual analysis, addressing new societal challenges. This expansion has been made possible by faster data acquisition and the development of theoretical foundations.

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.
