Textural and Thermal Analysis Service

Physisorption-Chemisorption




Scientific Responsibles
Dr. Gerardo Colón Ibáñez, Dr. Miguel Angel Centeno Gallego

Technical Assistant
Dª Cristina Gallardo López


This service constitutes a basic tool for the microstructural characterization of powdered solids of different natures, regarding to their porosity, specific surface area and chemically active surface.

This service is composed by a phyisisorption analyser (Micromeritics, ASAP 2020) which pro-vides the complete adsorption/desorption isotherms, from which the specific surface area, pore and micropore size distribution and concentration of reactive sites are obtained. The instrument is also equipped for carrying out chemisorption of different reactive molecules, as O2, H2, CO, etc.
 

Available Equipment

  • Analizador científico de fisisorción ASAP2010 (Micromeritics)
  • Analizador de quimisorción ASAP2010 (Micromeritics)
  • Analizador de fisisorción multimuestra TRISTAR II (Micromeritics)
  • Analizador de fisisorción multimuestra TRISTAR II-Kr (Micromeritics)

Thermal Analysis




Scientific Responsibles
Dr. Luis A. Pérez Maqueda

Technical Assistant
Dª Cristina Gallardo López


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).

Available Equipment

  • TA Instruments Q600 Simultaneous TG/DTA/DSC instrument
  • Thermogravimetric instrument TG, TA Instruments Q5000

Particle size and Z potential analysis




Scientific Responsibles
Dr. Manuel Ocaña Jurado

Technical Assistant
Dª Cristina Gallardo López


Dynamic light scattering (DLS) and Laser diffraction (LD) are available for the determination of particle size distributions of colloidal systems (dispersed in aqueous or organic dispersions solutions) in the range 3-3000 nanometers (DLS) and 0.05-900 microns (LD).

Electrophoretic mobility measurements can be also performed for the evaluation of Z potential in colloidal systems (aqueous or organic dispersions).
 

Available Equipment

  • Malvern model Zetamaster (DLS) and MalvernSizer (LD)
