Does anyone could tell me which kind of features should I consider between the techniques Laser-Induced Breakdown Spectroscopy and Laser Ablation Inductively Coupled Plasma Mass Spectrometry to buy an instrument that will be used in geological samples for a geochemistry fingerprint focused research?
Both use Laser Ablation for particle generation so the sample preparation step is minimal but I would like to know about the instrument and maintance costs (if somebody has a shallow idea about it), the detection limits and the advantages that have one over the other.
I deeply appreciate your help in advance.
Dear Cristhian,
I am not an expert on LA-ICP-MS, but what I know from literature is that the differences between LIBS and LA-ICP-MS are quite small. The results of the two techniques are comparable and in most cases the application determines which of the two is the best choice.
At SPECTRAL Industries we have a large experience with applying LIBS on chaological samples: drill cores, mine face and drill cuttings. If you like to learn more about our work and the LIBS instrument we have developed for geological applications, please contact me or visit our website: spectralindustries.com.

In both the instruments, LIBS and LA-ICP-MS, laser is used for the evaporation/atomization/excitation of the sample.
LIBS is a type of atomic emission spectroscopy in which laser is used for excitation.
If you want to study the isotopic compositions ( for age study of rocks) of the geological samples LA-ICP-MS is better option compare to the LIBS.
Dear Cristhian
I agree with Prof. Baig and Dr. Marijn. LA-ICP-MS system as well as its maintainance is costly. It has been proved that LIBS works better even for the geological sample and is faster than the LA-ICP-MS. Finaly you have to decide keeping all the points in your mind in the present situation.
