Here, we applied a combined Zr doping (<small><sup>94</sup></small>Zr/<small><sup>90</sup></small>Zr) and standard-sample-bracketing method (termed Zr-doped SSB) for mass bias correction during Sr isotope measurement. Prior to isotope analysis, Sr was purified using a two-step column procedure, achieving a total Sr yield exceeding 99%. Matrix elements such as Rb, Ba, Eu, Yb, and Ca were reduced to negligible levels, well below the matrix/Sr thresholds that would induce a significant analytical bias, as determined by doping experiments. <em>δ</em><small><sup>88/86</sup></small>Sr and <small><sup>87</sup></small>Sr/<small><sup>86</sup></small>Sr were simultaneously measured by the Zr-doped SSB method.

Through replicate measurements of Sr standard solutions (GSB Sr and NIST SRM 987) and geological reference materials (GRMs) (<em>e.g.</em>, IAPSO, BHVO-2, and AGV-2), long-term precision was found to be better than 0.03‰ (2SD) for <em>δ</em><small><sup>88/86</sup></small>Sr and 3 × 10<small><sup>−5</sup></small> (2SD) for <small><sup>87</sup></small>Sr/<small><sup>86</sup></small>Sr. These results were comparable to those acquired by <small><sup>92</sup></small>Zr/<small><sup>90</sup></small>Zr correction and the DS technique and better than those obtained using <small><sup>91</sup></small>Zr/<small><sup>90</sup></small>Zr correction.

Laser-Induced Breakdown Spectroscopy (LIBS) has demonstrated remarkable capability for quantitative compositional analysis of complex samples, such as Martian rocks and soils. However, traditional multivariate regression methods are difficult to capture the complex nonlinear relationships in LIBS data, while deep learning methods frequently suffer from high data dependency and low interpretability. To overcome this issue, this paper proposes a novel transparent and lightweight deep partial least square chemometric method inspired by deep learning, referred to as Ensemble Deep Kernel Partial Least Squares (EDKPLS). The model consists of multiple cascaded partial least squares modules with a radial basis function kernel inserted to capture nonlinear couplings between spectral lines. A latent variable ensemble strategy is utilized to alleviate the computational burden of latent variable selection and enhance predictive stability and generalization. To further improve the overall performance of the model, a multi-branch modeling approach is adopted, along with a dynamically weighted score function for parameter optimization. The proposed EDKPLS method is evaluated on the ChemCam LIBS dataset to validate its regression performance. The results across multiple analyzed components demonstrate that EDKPLS achieves lower RMSE and MAE values and higher <em>R</em><small>²</small> compared to several representative baseline methods.

Experimental evidence suggests that helium metastables transfer energy to trace amounts of water vapor present in the vacuum chamber. The plausible mechanism is the energy exchange between metastable helium and water molecules <em>via</em> Penning ionization. This occurs because the energy of helium metastables exceeds the dissociation energy of a water molecule and the ionization energy of hydrogen. The hydrogen ions that are formed subsequently combine with electrons in the plasma, resulting in the emission of the Balmer series during the subsequent relaxation process. The intensity observed in the Balmer lines indicates unconventional ratios between them, demonstrating a strong dependence on neutral pressure and RF power. This phenomenon is indicative of the role of the energetic tail population. The observation reveals a direct correlation between the intensity of Balmer line emission and the electron density. In order to comprehend the dependence of helium metastables on the Balmer series intensity, the collisional radiative (CR) model is employed to estimate the metastable population enhancement under the present experimental conditions. The observed enhancement can be attributed to the increase in metastable densities and the radiative recombination processes. The results of this study hold significant potential for applications, in addition to providing a fundamental understanding of energy transfer between the metastables of helium and water vapor.</p>","PeriodicalId":81,"journal":{"name":"Journal of Analytical Atomic Spectrometry","volume":" 4","pages":" 1505-1516"},"PeriodicalIF":3.1,"publicationDate":"2026-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147686514","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}

Direct LIBS quantification of marine aerosols, however, remains challenging due to the occlusion of particles within water droplets, which alters energy deposition and plasma formation. Here, we use laser pulse energy as an external perturbation to introduce an additional energy dimension into aerosol-LIBS spectra, and couple this modulation with two-dimensional correlation spectroscopy (2D-COS) to probe phase-dependent energy-coupling pathways. The results show that solid-phase aerosols mainly follow a direct “laser–particle interaction”, whereas liquid-phase aerosols are governed by a “plasma–particle interaction” initiated by water dissociation and subsequent air-plasma formation. This transition makes LIBS quantification particularly challenging for liquid-phase aerosols. Compared to conventional univariate calibrations, curves built from laser-energy-modulated 2D-COS intensities can track the dynamics of aerosol dissociation and excitation, resulting in markedly improved analytical sensitivity. To further tackle the multivariate and nonlinear nature of LIBS quantification, we build a multilayer perceptron artificial neural network (MLP-ANN) using spectra collected under single-energy and energy-modulated conditions. The results indicate that high-dimensional spectra improve stability and enhance prediction robustness. Thus, laser energy modulation combined with high-dimensional spectral analysis offers a practical route to both clarify phase-dependent energy coupling and improve the sensitivity, stability, and accuracy of direct LIBS quantification of marine aerosols.</p>","PeriodicalId":81,"journal":{"name":"Journal of Analytical Atomic Spectrometry","volume":" 4","pages":" 1480-1491"},"PeriodicalIF":3.1,"publicationDate":"2026-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147686522","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}
