The most successful and best suited for rapid identification of alloys in field has been Handheld X-Ray Fluorescence (HHXRF). However, the XRF has inherent difficulty in analysis of many important aluminum alloys as well as other alloys containing low atomic number elements such as lithium, beryllium, boron, silicon or magnesium. The common practice to overcome this deficiency has been use of Optical Emission Spectroscopy (OES) or – most recently – Laser Induced Breakdown Spectroscopy (LIBS). Both these techniques can analyze all alloys the XRF can and especially those the XRF cannot. Recent technological advancements made possible design of handheld analyzers based on LIBS which are especially well suited to analysis of aluminum alloys. In this paper we report on the design features of Rigaku’s KT-100S, micro-LIBS handheld analyser and discuss its performance in analysis and sorting of aluminum alloys, especially those containing light alloying elements such as Si, Li, Be, Mg.
