The organic matter within biomineralized minerals constitutes compelling evidence that sets them apart from inorganic minerals. However, for small samples that have undergone degradation and diagenetic alteration, routine analytical technologies have difficulties in identifying internal residual organic signals. Atom Probe Tomography, as the highest-spatial-resolution microanalytical technique, facilitates the study of elements spatial distribution and nano-scale structures, holding significant potential for applications in biogeochemistry. In this study, Atom Probe Tomography has been applied to fossil samples for the first time, comparing inorganic Durango apatite with fossil conodont. This research discovered residual organic components within conodont, manifesting in the form of nano-scale particles coupled with high carbon and nitrogen concentrations. This signal is promising for differentiating between biominerals and inorganic minerals, which is greatly potential for identifying nano-scale biosignatures in ancient samples.","PeriodicalId":8642,"journal":{"name":"Atomic Spectroscopy","volume":"22 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140415411","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}

This work successfully conducted the synthesis of a new nanomaterial (ZnMnAl LDH). The characterization of this material was accomplished utilizing many analytical techniques, including FTIR, XRD, SEM-mapping, and FE-SEM. ZnMnAl LDH was employed to separate and enrich Cu(II) and Ni(II) from soil and water samples. The Cu and Ni ions were eluted from ZnMnAl LDH nanoparticles by using 2 mL of 0.1 mol L −1 of HNO 3 . The metal ions were quantified using flame atomic absorption spectrometry (FAAS).

As reliable arsenic characterization and speciation techniques are available, a fundamental study was undertaken to shed light on the behavior of arsenic compounds (arsenic pentoxide, dimethylarsenic acid, and arsenobetaine within a cellulose matrix, along with pure elemental arsenic), using a pulsed 213 nm Nd:YAG laser and ablation in different gas atmospheres (He, Ar/CO 2 [99/1 %], Ar/O 2 [80/20 %], and O 2 ) at atmospheric pressure. The generated arsenic, collected in aerosol form on inline syringe filters (0.2 μm), was subjected to sequential dissolution, yielding water-soluble, HCl-soluble, and insoluble fractions. The water-soluble fraction was analyzed for arsenic species using chromatographic techniques in combination with element-specific detection. The analysis revealed that extremely complex processes take place during laser ablation, not only (partially) stripping organoarsenic species from their methyl groups and lowering the valence state, but also creating conditions for the synthesis of methylated arsenic species from arsenic pentoxide and generating more or less soluble nano/micro/macro particles for all arsenic compounds. These findings contribute to a more nuanced understanding of the multifaceted photochemical transformations that may occur during laser ablation of molecules.","PeriodicalId":8642,"journal":{"name":"Atomic Spectroscopy","volume":"19 3","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140411072","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}

The potential matrix effect-inducing elements in Sb isotope composition measurements exhibit extremely low concentrations in two newly introduced natural stibnite reference materials, DC and BJS, rendering their impact virtually negligible during fs-LA-MC-ICP-MS analysis. Through reciprocal correction of DC and BJS, consistent results were achieved, aligning with those obtained by SN-MC-ICP-MS, indicating an absence of discernible matrix effects between the two samples. A comprehensive assessment was conducted to evaluate the contribution of the Sn standard solution to enhance the external precision of measurements. The 2SD of δ 123 Sb mean values increased by 0.02‰ to 0.04‰. Adjusting the laser ablation spot size (5μm-80μm) to control signal intensity, we investigated the deviation in δ 123 Sb caused by mismatched signal intensities between the sample and the reference material. The matching range of signal intensity between the reference sample and the test sample was within -40% to 140%, ensuring satisfactory precision. Additionally, once the signal intensity of 121 Sb exceeded 15V, the internal precision of the 123 Sb/ 121 Sb ratio no longer exhibited a significant decline. Measurements of DC and BJS were conducted using fs-LA-MC-ICP-MS, coupled with SN-MC-ICP-MS, backscattered electron maps (BSE) and elemental compositions, confirming the accuracy of this method and the homogeneity of the two potential reference materials.","PeriodicalId":8642,"journal":{"name":"Atomic Spectroscopy","volume":"11 10","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140412869","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}
