| Abstract: | This work reports on a simple, quick-freeze method for the quantitative analysis of trace metal ions in liquids applying the laser-induced breakdown spectroscopy (LIBS) technique. Using this procedure with calibrated samples, well-characterized linear working curves were determined for Na and Al water solutions over the 0.01–1% concentration range. This allowed detection limits of the order of ppm. In addition, optimum experimental conditions were found that allow the analysis to be carried out in a fast and very easy manner, without the limitations and difficulties found with liquid samples. The advantages of this simple and direct method, developed and patented by the Instituto Pluridisciplinar–UCM, are discussed, and potential applications for industrial analysis are also suggested. |
