Abstract/Summary:
Laser-induced breakdown spectroscopy (LIBS) is a very promising elemental analysis technique. This thesis studied the effect of various parameters on the accuracy of laser-induced breakdown spectroscopy (LIBS) data taken from pellet samples, which were made from important materials, such as silica, alumina, and lime with polyvinyl alcohol, sucrose, and starch as binders. The dependence of the standard deviation of the LIBS data on the amount and nature of the binder used, pressure used to press the powder into a pellet, and the position of the focal spot on the pellet has been investigated. Calibration curves of the major and minor components of glass batch were obtained to demonstrate the usefulness of the results of preparation of pellets.
