| In this paper, a horizontal liquid jet is analysed for Indium. The detection limits are significantly enhanced by the use of 1.2kW microwave source. Largest enhancement occurs at a laser fluence of 85J/cm^2, with enhancement decreasing with increasing laser fluence. Detection limits for LIBS and Microwave Assisted LIBS are presented | |||||
