A software system for rapid analysis of plastics using laser-induced breakdown spectroscopy

Abstract

With the extensive use of plastic products, the recycling and reuse of plastics raises more concerns. Laser-induced breakdown spectroscopy (LIBS) has become a powerful technology for plastic analysis. To meet different analytical requirements, LIBS control system and analysis software was being continuously developed. However, existing software system only can realize the capability of LIBS system control or data analysis (peak detection or material identification). To improve the efficiency of LIBS instrument for plastic analysis, an integrated and full software is needed. In this work, analyis & test software was developed for rapid plastic analysis, which consists of LIBS control platform, plastic database, and analysis module which contains peak detection, qualitative and quantitative analysis. The software performance was validated, which provides an automatic processing for plastic analysis. Design approach of the software can be used for the development of similar instrument software and other samples analysis.
