ABSTRACT
Laser-induced breakdown spectroscopy (LIBS) was applied to perform qualitative research on Tibetan medicine “GTso Thal” in order to establish a rapid element analysis method . The Nd YAG laser with the funda-mental frequency at 1064 nm was used. A high-power laser beam was focused on the surface of the sample. The spectrometer and CCD was used to detect its spectrum signals. Based on the National Institute of Standards and Technology (NIST) database, emission spectrum characteristics were differentiated. The LIBS spectra of “GTso Thal”showed multi-elements including Hg, Ca, Na, As, Fe, Mg, Al, K, Li, Pb, Ag, Au and S. Among them, Hg, Pb, Ag and Au were heavy mental elements. The results demonstrated that LIBS was a viable technique for analysis of Ti-betan medicine “GTso Thal”. LIBS provided reliable elemental analysis on Tibetan medicine “GTso Thal”. The de-tection was real-time, rapid and in situ. It had prospects in the elemental analysis of ethnic medicine study. LIBS had broad application prospects.
