    A remote laser-induced breakdown spectroscopy device was constructed by combination a nanosecond Nd: YAG laser with a Cassegrain telescope. The distance of measurement can be up to 25 m. In addition, the quantitative analysis of micro elements, Pb, Fe and Ni, in the standard sample of aluminum alloy at different distances is studied. The experimental results show that the correlation coefficients of the calibration curves for Pb, Fe and Ni are all higher than 0.97 at the distances from 5 to 20 meters. Though the intensity of spectral signals decreased rapidly with distance, there was not significantly different of the limits of detection with the increase of measurement distance in our experiments.
