Thermal analysis techniques allow to studying physical or chemical changes occurring in solid in samples as a function of the temperature. Those changes should involve either a mass change or a heat flow.

The experiments can be performed in the range from room temperature to 1500ºC, both under inert (N2), or reactive (air, O2,…) atmospheres.

Two different techniques are available: Thermogravimetry (TG) and Differential Thermal Analysis (DTA).

Formulario ICP.docx

Inductively coupled plasma atomic emission spectrometry (ICP-OES) is an analytical technique that allows the quantification of elements up to the trace level in samples in solution. The sample to be analyzed is nebulized and conducted to an argon plasma, where desolvation, vaporization, atomization and ionization of the elements take place. The atoms and ions reach an excited state by the high thermal energy supplied by the plasma and during the relaxation process electromagnetic radiation is emitted with wavelengths characteristic of each element. The intensity of the different emission lines is proportional to the concentration of the elements, which can be quantified by using appropriate calibration curves. This technique has high detection limits (in the ppb range, μg / L), good reliability, high throughput and multi-elemental capacity, although in some cases spectral interferences can occur due to a high number of emission lines.

Solid samples (digestion will be carried out by the service) or liquid samples in slightly acidic aqueous solution can be supplied. Samples in HF medium are not allowed. Liquid samples must not present precipitates or colloids in suspension and must have a minimum volume of 10 ml. The samples will be delivered to the technician in charge of the service, together with the duly completed analysis request that is available on the ICMS website.

Infrared spectroscopy (FT-IR) is based on the selective absorption of the infrared radiation by the materials. This absorption means a change in the vibrational energy of the chemical bonds, whenever it occurs a change in the polarization. The result is a spectrum showing the absorbed or transmitted radiation as a function of the wavenumber of the radiation, which can be assigned to the corresponding chemical bound.

The equipment at the ICMS works in a wavenumber range from 5000 to 250 cm-1 (CsI optic), and can operate with a gas purge or in vacuum. It is equipped with several accessories to do Diffuse Reflectance (DRIFT), Attenuated Total Reflectance (ATR) or Specular Reflectance.

Raman spectroscopy is based on a photonic process in which the incident radiation is dis-persed by the sample. This latter is perturbed leading to vibrational and rotational transitions. In general, the Raman spectrum is interpreted like a vibrational one, providing information very similar to the infrared spectroscopy, although the Raman active vibrations are not always the same as those excited with infrared radiation. A Raman vibration mode is active if there is a change of polarizability of the chemical bonds or the considered molecule, which in turn results in the generation of induced dipolar momentam. Its application fields are very broad: semiconductors, carbon compounds (graphite, diamond, nanotubes, fibers…), catalysts, pigments, etc.

Typically, “photoelectron spectroscopies” are a powerful set of non-destructive analysis techniques, exclusively sensitive to the more superficial few atomic layers (20-30 Å), allowing to obtain valuable information about their chemical, physical and electronic properties.

The technical interest of the resulting information is huge in fields such as catalysis, corrosion, surface treatments,, floating and adhesion phenomena, or segregation processes, among others. The most remarkable characteristic of X-Ray Photoelectron Spectroscopy (XPS/ESCA) is that it allows to discriminate, for a given element, between different oxidation states or chemical surroundings (coordination).

Contact Angle and Surface Tension Determination Service

Protocolo_wetting.pdf

Formulario_wetting.pdf

Advanced characterization of wetting using a goniometer to determine the contact angle of liquid droplets deposited on a surface is a quantitative and non-destructive analysis technique in general, depending on the surface reactivity with the wetting liquid. The combination of several liquids allows to determine the surface tension of the wet solid and to estimate the work of adhesion in simulated environments. The control of the wettability of smart surfaces under the action of external stimuli such as the application of light, temperature and/or humidity gradients, changes in pH or electric fields, are of great interest in advanced applications for the aeronautical industry, lines of communication, transportation, protection, heritage, solar and wind energy or biomedicine, among others.

Determination of the contact angle is carried out by applying Young's equation for interfacial tension balance, with sensitivity at the nanometric scale. The tests can be carried out in static or in dynamic modes to obtain hysteresis (advanced and receding angle values) of surfaces and critical values ​​of droplet sliding. Regarding the surface tension of the solid surface, implemented theoretical models are those of Owens, Wendt, Rabel and Kaelble, Extended Fowkes, Schultz and Van Oss&Good and Neumann, based on the existence of polar and dispersive components. In addition, the temporal tracking of the surface contact angle accounts for aging and stability in certain environments. Finally, the assistance of a controlled temperature and humidity chamber allows studies of condensation/evaporation and freezing/thawing of water on surfaces.

The contact angle and surface tension measurement equipment has been supported by the Junta de Andalucía (Aid for R&D infrastructure and equipment 2019-PAIDI2020 European Regional Development Fund)
