Sessions Information


The CSI XLI will be held in parallel with the first Latin-American Meeting on Laser Induced Breakdown Spectroscopy (LAM-LIBS). Typically, the CSI has a laser spectroscopies session (including LIBS), but in this edition part of that session will correspond to the LAM-LIBS.

The programme will consist of plenary lectures (45 min including discussion), given by distinguished scientists, on different fields of spectroscopy. These lectures will be held in common sessions between CSI and LAM-LIBS. 

Parallel sessions will take place in five rooms in the conference venue.
