Description
Laser-induced breakdown spectroscopy (LIBS) has emerged as a versatile technique for elemental analysis, offering high-resolution and real-time measurements, while being minimally destructive. This powerful analytical technique holds significant promise in various fields, including academia, technology, and industry. However, several challenges hinder its widespread adoption and limit its potential impact in these sectors.
In INESC TEC we work closely with all these domains trying to identify and address these challenges while exploring the prospects for LIBS in different applications. Some examples of LIBS implementation in prospection and geology [1], in cork [2] and wood industries and in electrodes assessment for Li batteries will be shown. The main challenges such as quantification, lack of data analysis algorithms, integration with complementary techniques and adaptation to diverse sample matrices, among others, will be addressed.
Despite the challenges, several promising opportunities are emerging in the LIBS landscape. The conviction that gold standard techniques are always the best option is getting more and more contradicted. Novel methods, such as LIBS, are often fit for purpose offering enough data quality, but also unsurpassed savings in time, labor and price.
