Abstract: |
Laser-Induced Breakdown Spectroscopy (LIBS) has proven to be a promising and versatile chemical analysis technique with the potential to revolutionise the industrial sector. Its numerous advantages, including minimal or no sample preparation, rapid real-time analysis, and multi-element detection[1], make it a valuable tool across various fields of application.
This study addresses the applicability of LIBS in distinct industrial sectors, focusing on cork, minerals, glass and wood waste. In cork analysis, LIBS was employed to assess the quality of functional coatings deposited on cork stoppers, ensuring product performance[2]. In the particleboard industry, LIBS was utilised to detect hazardous materials in recycled wood wastes, ensuring its safe incorporation into new particleboard production and promoting sustainable practices[3]. In the mineral sector, LIBS demonstrated its capacity to analyse the chemical composition of various rock samples, enabling the determination of their mineralogical composition[4]. This can help to improve mineral classification tasks and resource exploration studies such as for Lithium prospection purposes.
This work underscores the potential of LIBS to enhance industrial processes by providing fast, accurate, and reliable analytical capabilities. Its application speeds up material’s chemical analysis and supports sustainability across diverse materials and industrial applications.
