Catching up on Calibration-Free LIBS

This review paper will present and critically discuss the evolution of the Calibration-Free LIBS (CF-LIBS) method and some of its new applications that appeared since the last extensive review on the topic, that was published more than 10 years ago by the inventors of the technique. This will allow the interested researchers to catch up the new trends of the method and the strategies that have been devised in the last decade for improving the analytical factors of merit of CF-LIBS.
