Comparison Of The Analytical Performances Of Laser-Induced Breakdown Spectroscopy And Spark-Oes

Most Czerny-Turner based LIBS systems are used widely. In the present work, an instrumental setup based on Paschen-Runge is introduced, and analytical parameters are optimized for LIBS. With optimum parameters, analytical performance measures, such as precision, accuracy and detection limit, are compared for LIBS and Spark-OES. The results show that the analytical accuracy obtained by LIBS is similar to that obtained with Spark-OES, while the precision and detection limit are notably close to those of Spark-OES. Thus, LIBS can be used satisfactorily for process analysis in the metallurgy industry.
