    Abstract

    A new and reliable evaluating method for a laser induced breakdown spectroscopy (LIBS) quantitative measurement using a micro-droplet sample ejection system is introduced. LIBS has been investigated extensively to establish proper chemical analysis of specimens. There is an indefinable boundary which is ablated or not when laser focusing on the sample. Generating micro-droplets from concentration tuned solution, and leading to the correct beam spot area are important for determining the total amount of media in a droplet. The LIBS measures the sodium chloride concentration of a micro-droplet as a quantitative measurement by recording intensity from the sample plasma. As a result, LIBS with the micro-drop ejection system produced greater intensities than the old technique of bulk-liquid measurement based on data from 100 laser pulse shots.
