Development of softwarw for characterization of C in soils using LIBS with applications for embedded systems.

Analysis of the soil chemical composition is of fundamental importance. The standard method for soil analysis is made getting random samples from an area at different depths, and sending to a laboratory for elemental determination, using analytical techniques (e.g. ICP, CHNS and AAS). The mains problems of this type of characterization are: chemical waste, cost and long time for sample preparation. Laser-induced breakdown spectroscopy (LIBS) is a technique which allows real time evaluation of the elemental composition of solid, liquid and gaseous samples. In this work, software for analyzing LIBS spectra were developed using Python, and a quantification of C in a test sample and actual soil was made.
