Abstract: | In the framework of the development of new techniques, the ability of laser-induced breakdown spectroscopy (LIBS) to analyse
remotely complex aqueous solutions was investigated. The jet configuration with a collimated gas stream was chosen because
it appeared to be the most promising method for the LIBS probe, particularly in terms of sensitivity and repeatability. For
emission collection, the echelle spectrometer offers a simultaneously recorded wavelength range from the UV to the near IR
and is interesting for multielemental analysis for LIBS and also for inductively coupled plasma (ICP) optical emission spectroscopy
(OES). The importance of parameters influencing the quantitative results of LIBS such as multispecies analysis, sheath gas,
use of an internal standard and temporal parameters for analysis is described. LIBS quantitative data have been directly compared
with results from the more standard ICP/OES technique. |
