Research Abstract

In situ analysis of impact ages for meteorites needs to determine small amounts of Ar and K. Low background 40Ar (~ 108atoms) for the mass spectrometer has successfully been achieved. In addition, the LIBS (Laser-induced breakdown spectroscopy) system has been developed. Potassium in terrestrial andesite was detected using the LIBS system.
