INSTRUMENTATION
Experimental Probes and Facilities
ARPES (Angle-Resolved Photoemission Spectroscopy) is an experimental technique that directly measures the binding energy of the emitted electrons’ initial state as a function of the reciprocal space’s momentum photons of a well-defined energy hν is incident upon a simple. Our group has participated in the installation, commissioning and standard operation of a brand-new ARPES and Spin-ARPES set-up in the context of
Synchrotron and Neutron facilities:
Synchrotron and Neutron sources are also used complimentary for diffraction experiments of mono and polycrystals samples, mainly in the experimental stations: XX, XX.
For ARPES, core-level photoemission, and X-ray absorption (NEXAFS), SR offers flexibility in varying photon energy, optimizing matrix element effects to optimize ARPES spectra and tune high and low core level edges for NEXAFS. Our group uses several European Large Facilities, utilizing several different beamlines: ARPES, nano-ARPES, core-level photoemission, and NEXAFS for photon energy range 21 eV to 1000 eV in ANTARES beamline in SOLEIL and ALBA synchrotron sources.
NMR (Nuclear Magnetic Resonance) laboratory.
Nuclear Magnetic Resonance (NMR) Laboratory expertise from Intertek supports clients across the world. NMR laboratory observation of any NMR-active nucleus in the periodic table is posible. NMR is a powerful technique that can provide information on molecular structure and dynamics at the atomic level. It has been widely used in chemistry, polymer and biology, with rapid analysis and reporting times. NMR active nuclei studied include 1H, 11B, 13C, 19F, 27Al, 29Si, and 31P.
NMR laboratory instrumentation: 500 MHz NMR. Z-gradients for diffusion measurements and gradient-selected techniques. Multidimensional techniques: 1H, correlation spectroscopy (1H-COSY), Total correlation spectroscopy (TOCSY), Heteronuclear single-quantum correlation spectroscopy (HSQC), Heteronuclear multiple-bond correlation spectroscopy (HMBC), Nuclear Overhauser effect spectroscopy (NOESY), and Incredible natural-abundance double-quantum transfer experiment (INADEQUATE). ?
The instruments is equipped to cover many sorts of NMR experiments and analyses:
Most NMR active nuclei can be studied
Possibilities for variable temperature experiments (77K – 623K) ?
A gas flow probe can be used to study gas-solid reactions up to about 623 K at 1 atm pressure. ?
Our researchers and technicians are familiar with many different type of experiments (1D and 2D) for a range of nuclei (incl. dynamic studies) for both liquid and solid samples. They have also experience in the use of various data simulations and in inert treatments of samples.
