Analytical Services involve chemical analysis of materials to understand the chemical makeup of any material. Chemical analysis in turn involves elemental analysis, isotope analysis and molecular analysis. A variety of techniques are used to determine elemental and molecular chemistry of materials. More common is the spectroscopic method, which uses high energy beams such as X-Rays, gamma rays, laser, and microwave and particle beams such as electrons neutrons. Spectroscopy methods are further categorized into emission or absorption spectroscopy. The analyte is irradiated by one of the energy or particle beams and the absorption or emission by the analyte is analyzed and compared to pre-determined reference or standard materials. Other less commonly used methods involve wet chemistry, chromatography, etc. In addition to the chemical makeup of materials, it may be necessary to understand the material structure in terms of phase composition, crystal structure and other thermochemical properties such as heat content. Again the material to be analyzed is irradiated using energy or particle beams, then the diffracted or emitted beams are analyzed for characters unique to individual compounds or phases.
