Types of analyses:

Nuclei analyses between the 31P and 109Ag resonance frequencies. 1H and 13C mono and bi-dimensional analyses. List of possible analyses:

• 13C RMN. Molecules' structure determination. Results are presented in the form of images (spectres), intensity graphs versus resonance frequency.
• 13C RMN enables the characterization of Carbon atoms in one molecule (methyl, methylenes and quaternary carbons). The results are presented in the form of images (spectres), intensity graphs versus resonance frequency.
• 13C-1H bi-dimensional spectre. It specifically shows correlations to a (1JC-H) bond between Carbon and Hydrogen atoms. It is especially useful for the allocation of quaternary carbons. The results are presented in the form of bi-dimensional images (contour diagrams), intensity graphs versus resonance frequency. 13C frequency versus 1H frequency.
• 13-C-1H bi-dimensional spectre. It specifically shows correlations to more than one (1JC-H and 3JC-H) bond between Carbon and Hydrogen atoms. It is especially useful for the allocation of quaternary carbons. The results are presented in the form of bi-dimensional images (contour diagrams), intensity graphs versus resonance frequency. 13C frequency versus 1H frequency.
• 1H RMN. Determination of molecules' structure and composition of mixtures. It is especially useful for the allocation of quaternary carbons. The results are presented in the form of images (spectre), intensity graphs versus resonance frequency.
• 1H-1H bi-dimensional spectre. It specifically shows H-H correlations (Njh-h). Results are presented in the form of bi-dimensional images (contour diagrams).
• 1H-1H bi-dimensional spectre. It specifically shows dipolar couplings. It is a very useful technique for the allocation of relative configurations and molecules stereochemistry. Results are presented in the form of bi-dimensional images (contour diagrams).
• X nuclei RMN whose frequency is within the range of 129Ag and 31P. For example 11B, 15N, 21Al, 31P. Determination of molecules structure. Types of samples: The analysis is in some cases strongly limited by the characteristics of the nucleus to be observed, natural abundance, sensitivity, nuclear spin, etc. Results are presented in the form of images (spectre), intensity graph versus resonance frequency.

Types of analyses:

The X-Ray diffraction analysis, in powder samples, is used for the structural identification of all types of crystalline compounds of inorganic, organic and mineral nature.

Types of analyses:

The service provided will be related to the objective aimed at by the researcher and to the type of material to be analysed.

The main analytic techniques that can be developed are:

• Qualitative and quantitative Wavelength Dispersion X-Ray Microanalysis (WDX), for elements with an atomic number higher than Boron; results are presented in a list of oxides (by means of stechiometric calculus) or elemental and/or cationic. Equally, it allows the realisation of compositional profiles and element distribution mapping.
• Scanning Electronic Microscopy (SEM).
• Conventional and digital microphotography: images of secondary, retro-dispersed and absorbed electrons, X-ray images and X-ray spectres.
• Analysis of digital and photographic images, and videos in which you can observe reactions and events at micrometric scale and which occur in real time.
