Abstract :
Laser induced breakdown spectroscopy (LIBS) has been used for the determination of the species and concentration of elements in industries. However, there is less research for LIBS analysis of agricultural and environmental samples. In this work, a LIBS system has been evaluated for the determination of nutrition elements in orange leaves. The experimental setup was designed by using a Nd:YAG laser operating at 1064 nm (200 mJ per pulse and 5HZ repetition rate) and an Avantes spectrometer (200-1100nm wavelength range)with ICCD detector. The species and relative contents were identified by LIBS spectra, which belonged to qualitative analysis. The quantitive analysis will be carried combining with routine analysis such as ICP-OES.
