摘要：

The laser-induced breakdown spectroscopy (LIBS) using micro-droplet sodium chloride solution is presented. Since the 1980s, many liquid miniaturizations of analytical technique for LIBS measurements were reported. The method we present allowed micronizing the sample in such a way that whole volume of a sample was confined in the laser beam spot area (minimum beam spot diameter 53.2μm, microdroplet diameter 50-60μm) and was separated from its surrounding condition. If the sample's physical state was liquid, the density of solution could be controlled as needed. In this paper, originally designed ink-jet system for sampling procedure was presented. According to the new method, improved sensitivity for drawing calibration curves with the aim of the LIBS quantitative measurement were obtained.
