![]() The team says that its LIBS technique could someday be used to quickly and affordably monitor water-supply quality and identify potential contamination in situ and in real time. Using their technique, which employs acoustic-wave levitation to suspend and pre-concentrate the water droplets for more accurate chemical analysis, the researchers obtained reproducible measurements of minute quantities of barium, cadmium, mercury and lead in deionized water-based samples. Ī team of researchers from Mexico has developed a way to use laser-induced breakdown spectroscopy (LIBS), a technique commonly used to analyze solid samples, to detect very low concentrations of heavy metals in individual water droplets (Opt. A research team in Mexico used sound waves to levitate droplets of water, and enable the liquid samples to be chemically analyzed for heavy-metal contaminants using laser-induced breakdown spectroscopy (LIBS). ![]()
