Short summary
This study presents a new method designed to analyze micrometer-scale chemical and isotopic profiles in minerals, glasses, and other solids. The employed technique combines plasma mass spectrometers and a state-of-the-art femtosecond laser equipped with open-source software (LinuxCNC) that controls the movement of the laser beam. It allows for equably drilling into the sample surface, e.g., in order to measure chemically or isotopically zoned or heterogeneous materials at micrometer scales.
