GELP researchers in collaboration with former GELP member Dr. Álvarez-Llamas have been awarded a Spanish patent ES2958384 entitled Método para la identificación y determinación de halógenos en muestras liquidas mediante espectroscopia de ruptura inducida por laser asistida por nebulización (Method for the identification and determination of halogens in liquid samples through nebulization-assisted laser-induced breakdown spectroscopy).
The patented methodology allows for the qualitative and quantitative study of halogens in liquid samples by means of nebulization of the liquid on an alkali-earth-containing solid substrate. The deposited liquid is ablated with a fraction of the solid target, and the presence of halogens is made apparent through the molecular emission resulting from diatomic molecular species formed through recombination of the alkali-earth metal and the halogen in the plasma.
