title = "Sensitive elemental analysis of aqueous colloids by laser-induced plasma spectroscopy",
abstract = "The sensitive elemental analysis of aqueous colloids was analyzed using laser-induced plasma spectroscopy. The lead emissions were enhanced by minimizing the background continuum interference. The results showed that the detection limit for lead was 14.2 ppb, compared with 13ppm achieved by conventional laser-induced breakdown spectroscopy of lead ions in water and 210 ppb for lead aerosols.",
