    Abstract

    A new and reliable set-up for laser-induced breakdown spectroscopy (LIBS) which enabled the precise micro-droplet observation and guiding the solution samples into a laser beam spot area was designed. The method presented here allowed micronizing of the liquid sample confining the whole volume of the sample in the laser beam spot area (minimum beam spot diameter 53.2um, micro-droplet diameter 30-40μm), separating it from its surroundings. 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. Advantages of this method were: strong emissions, no sample splashing, solution density controllability and ho chemical denaturation. This experimental set-up helped to overcome the disadvantage of LIBS with a micro-drop ejection system.
