In this work, trace elements of rubies from Myanmar, Madagascar and Mozambique were investigated by using the LA-ICP-MS technique. The iron concentration in the rubies from Madagascar and Mozambique are higher than 1000 μg/g while the titanium concentration is less than 5 μg/g. In the Myanmar marble-hosted ruby, the iron concentration is below 10 μg/g while titanium concentration of a few thousands' μg/g is generally detected. The X-ray absorption near edge structure (XANES) spectra were taken from the high iron containing and marble-hosted rubies for obtaining the chemical information of iron and titanium, respectively. The XANES spectra reveals that trivalent iron is the major species in rubies of high iron rubies. Similarly, Cr K-edge XANES spectra are obtained for Cr³⁺ in rubies from two different sources. Ti K-edge XANES spectra in ruby from Myanmar show a 4+ oxidation state, and its XANES spectrum resembles that of TiO₂ with a rutile phase.</div></div>","PeriodicalId":21890,"journal":{"name":"Spectrochimica Acta Part B: Atomic Spectroscopy","volume":"232 ","pages":"Article 107271"},"PeriodicalIF":3.2,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144623523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Selenoneine has a strong antioxidant capacity which makes it a potential Se supplement for humans or farm animals. There is a lack of a reliable and cost-effective online speciation methodology for the determination of such a biologically relevant Se species. In this study, a method has been developed for the simultaneous analysis of selenoneine and other organic Se species. It is based on the online coupling of reversed-phase liquid chromatography, ultraviolet radiation, thermal treatment, hydride generation and atomic fluorescence spectrometry (HPLC-UV-TT-HG-AFS). Quantitative determination of selenoneine by external calibration and its separation from commonly found organic Se species (selenomethionine, <em>Se</em>-methyl-selenocysteine) was achieved. The proposed methodology resulted in a linear response (R² &gt; 0.999) for a concentration range of 5–100 μgSe L⁻¹ and a limit of detection of 0.5 μgSe L⁻¹. The repeatability was 0.8 %, with a reproducibility of 1.6 %. This analytical approach is versatile, cost-effective, and fast with a chromatographic runtime of less than 12 min. The high selectivity of HPLC-ICP-MS, combined with the species identification power of HPLC-ESI-MS/MS was found invaluable for gaining further speciation insights and confirming the results obtained by HPLC-UV-TT-HG-AFS. The developed approach could serve as useful tool for routine selenoneine analysis in biological samples as shown here with the analysis of seabird liver extracts.</div></div>","PeriodicalId":21890,"journal":{"name":"Spectrochimica Acta Part B: Atomic Spectroscopy","volume":"232 ","pages":"Article 107261"},"PeriodicalIF":3.2,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144604462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the validity of acquired results greatly depends on multiple factors, such as the sample matrix, pre-treatment protocols, the used analytical technique, appropriate standardization, calibration strategies, and the adequacy of the selected reference materials. Samples such as excavated skeletal remains prove to be particularly challenging to characterize using mass spectrometric techniques, as these require extensive pre-treatment procedures, and display a phosphate-rich, calcium (Ca)-heavy matrix, leading to potential interference effects upon ionization within the plasma. In this study, strontium (Sr) concentration analyses of 98 calcined archaeological bone samples are determined relying on HR-ICP-MS and ICP-QQQ-MS, using well-established concentration determination protocols. The applied procedures and HR-ICP-MS and ICP-QQQ-MS measurement routines are considered fully suited for the concentration determination of Sr in a Ca-heavy matrix, provided that Ca-normalizations of the acquired Sr data are carried out. It was found that the Sr concentration data from MC-ICP-MS correlate well with the data obtained relying on HR-ICP-MS and ICP-QQQ-MS, implying that MC-ICP-MS is also suited for Sr concentration determination in given sample matrices with the described procedures, saving both resources and time. The acquired data is also fully comparable with HR-ICP-MS and ICP-QQQ-MS data for Sr-isolated solutions, where the sample matrix was removed. The findings of this study, tested on cremated bone material, open up novel method development perspectives on other Ca-heavy samples, such as shells, speleothems, phosphate minerals and limestones.</div></div>","PeriodicalId":21890,"journal":{"name":"Spectrochimica Acta Part B: Atomic Spectroscopy","volume":"232 ","pages":"Article 107259"},"PeriodicalIF":3.2,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144604461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a previous study we found by bulk X-ray absorption spectroscopy (XAS) that besides Ag₂S, a secondary Ag<img>S species was present in sewage sludge and soils. This species accounted for 24–36 % of total silver. The objective of the present work was to investigate the nature of this Ag<img>S species. A combination of X-ray absorption near edge structure (XANES) spectroscopy at Ag K and L_III edges at micro and nano resolutions and of S K-edge micro XANES were used. Nano X-ray Fluorescence (nXRF) was used to investigate the nanoparticle size distribution and to evaluate the presence of mixed metal sulfides. We identified the secondary Ag<img>S species as Ag bound to thiol groups of organic matter (Ag-thiolate). It was present around the Ag₂S-NPs, and likely resulted from the complexation of Ag⁺ by thiol groups of soil organic matter. Ag₂S-NPs displayed a variety of sizes, with 10 % to 40 % of particles bellow 100 nm. Mixed metal sulfides were also present. This study improves our understanding of the fate of Ag-NPs in terrestrial environments, highlights the potential reactivity of Ag₂S-NPs in soils, and shows the primary role of soil organic matter as a sink for released Ag⁺.

This technique offers advantages such as fast signal acquisition, remote sensing capabilities, and no need for sample preparation. Herein, we acquired and analyzed LIBS spectra from a series of weathered samples collected from a basaltic chemical weathering profile in Hainan Island, China, serving as a Martian analogue, under Martian conditions. We derived the major elemental concentrations (Si, Ti, Al, Fe, Mg, Ca, Na, K) from LIBS data and discussed the influence of weathering degree on quantitative results. Then the weathering degree was calculated using both conventional approaches (utilizing elemental abundance derived from LIBS data) and our proposed partial least squares (PLS) models (which describe the relationship between weathering degree indexes and LIBS data). The weathering degrees derived from our models were more accurate than the traditional approach because our PLS models identified the potential weathering information in LIBS data.
