LIBS Info: Element Analysis

Title Authors Material Detector Spectrometer Software
Improvement of the sensitivity for the measurement of copper concentrations in soil by microwave-assisted laser-induced breakdown spectroscopy Martin Richardson, Matthieu Baudelet, Bruno Bouquet, Yuan Liu Soil Princeton Instruments ICCD Max Princeton Instruments Grating Spectrometer
Laser: Nd:YAG
Gate Delay: 0.500us
Gate Width: 2000.000us
The authors use MA-LIBS (Microwave assisted LIBS) to analyse pelletized soil samples. With the increased sensitivity, some increase in variability due to sample inhomogeneity was also detected.
