| Property / summary: Laser ablation systems, based on lasers with ultra-short pulses (femtoseconds), were originally developed for the nanoscale machining of components in the semiconductor industry. However, these types of lasers coupled to both optical emission spectrometers and mass spectrometers with ICP ionisation sources allow chemical analysis of solid samples with high sensitivity and high spatial resolution. The main advantage of this technique is its negligible collateral damage in the ablation process (e.g. minimal thermal effects around the crater created by the laser-matter interaction). At present, the University of Oviedo does not have such a laser ablation equipment, although it does have optical and mass spectrometers to couple this technology. Therefore, the acquisition of this infrastructure would allow its use in numerous multi-disciplinary applications related to chemical analysis with high spatial and deep resolution of metallic and non-metallic materials, as well as biological and geological/mining samples. In particular, different regional, national and international companies and institutions active in the production and characterisation of metals and glass have already shown interest; as well as national and international research groups dedicated to biochemistry, geology, mining resources, soil recovery, etc. (English) / rank | |||||||||||||||

Los sistemas de ablación laser, basados en láseres con pulsos ultracortos (femtosegundos), fueron originalmente desarrollados para el mecanizado, a escala nanométrica, de componentes en la industria de semiconductores. Sin embargo, este tipo de láseres acoplados tanto a espectrómetros de emisión óptica como a espectrómetros de masas con fuentes de ionización ICP, permiten el análisis químico de muestras sólidas con alta sensibilidad y alta resolución espacial. La principal ventaja de esta técnica es su despreciable daño colateral en el proceso de ablación (e.g. mínimos efectos térmicos alrededor del cráter creado por la interacción laser-materia). En la actualidad la Universidad de Oviedo no dispone de un equipo de ablación laser de estas características, aunque sí dispone de espectrómetros ópticos y de masas donde acoplar esta tecnología. Por tanto, la adquisición de esta infraestructura permitiría su utilización en numerosas aplicaciones de carácter multi-disciplinar relacionadas con el análisis químico con alta resolución espacial y en profundidad de materiales metálicos y no metálicos, así como de muestras biológicas y geológicas/mineras. En particular, ya han mostrado su interés diferentes empresas e instituciones regionales, nacionales e internacionales dedicadas a la producción y caracterización de metales y vidrios; así como grupos de investigación nacionales e internacionales, dedicados a la bioquímica, geología, recursos mineros, recuperación de suelos, etc. (Spanish)
