SOBRE MÍ
Alicia Garcia Garcia obtuvo su licenciatura en Química por la Universidad de Valladolid (España) en el año 2022. Tras obtener el título de Máster en Técnicas Avanzadas en Química.Análisis y control de calidad químicos por la misma universidad, actualmente es estudiante de Doctorado en el Departamento de Química Analítica en el grupo de investigación “Métodos Grupo de investigación Rápidos de Análisis con Técnicas Espectroscópicas – MARTE”.
Con experiencia con equipos de espectrometría atómica (ICP-MS, HR-ICP-MS, ICP-OES, MC ICP-MS y AAS), de ablación láser, absorción atómica y en salas blancas para el análisis elemental e isotópico, que desarrolló en el Departamento de Series de Uranio del Centro de la Evolución del Ser Humano-CENIEH (Burgos, España) y a su participación en el Grupo de Investigación de Marine Chemistry and Biogeochemistry-NTNU (Trondheim, Noruega), donde trabajó en los proyectos The Nansen Legacy y BEST-Siberian.
Su investigación se centra en el desarrollo de nuevos métodos para ablación láser acoplada a espectrometría de masas ICP (LA-ICP-MS). La defensa pública de su doctorado está prevista para 2027.

abstract = {This work introduces a novel method for generating the calcium monofluoride (CaF) diatomic molecule by adding the molecule-forming reagent in the gaseous phase (a methyl fluoride-argon mixture), in order to perform laser-induced breakdown spectroscopy (LIBS) and laser ablation molecular isotopic spectrometry (LAMIS) measurements. By optimizing the instrumental parameters, CaF molecule formation was successfully achieved within the plasma plume, upon ablation of dried liquid samples. The isotopic shift for the X2Σ→A2Π (0,1) CaF vibronic transition at 583.0 nm was calculated to be 292.3 pm. The method proved capable of providing quantitative information for determining calcium concentrations in real samples, such as tap water and skimmed milk, using internal standardization (with Sr as internal standard; limit of detection, LOD, 20 mg L−1) and isotope dilution (which can be applied from 400 mg L−1on), respectively. Partial least squares regression (PLS) analysis was employed to enhance the quality of the isotopic data. The Ca concentration found in the tap water was 47 ± 16 mg L−1 (reference flame atomic absorption spectrometry, FAAS, value: 59 ± 0.2 mg L−1), and 1100 ± 140 mg L−1 for the skimmed milk (reference FAAS value: 1240 ± 120 mg L−1). No significant difference between LIBS and FAAS results could be established using a t-test at the 95% confidence level. Overall, this novel approach allows for the determination of calcium in terms of both the elemental concentration and the isotopic composition, thus broadening the applicability of LIBS (e.g., for tracer experiments, besides the already mentioned application of isotope dilution).},
