Instruments for Monitoring Experimental Reactions

The study of the generic levitra uk dynamic behavior of materials is complex, since it often requires several instrumental techniques to understand the physical and community viagra free trial pack chemical processes. With complex and not understood systems, the concept of cures reproducibility is important. The number of parameters, controlled or not, is often too large. This means that several measurement instruments, including X-ray diffraction, will be set up around a single cell sample, to be followed in real time the evolution of structural modifications. The effects of changing various parameters (pressure, temperature, gas flow...) will then be directly recorded by all instruments.

SAXS WAXS experiments combined with a Raman spectrometer for thermal studies

Proteins are essential components of all living organisms. Involved in many biological processes, they may be therapeutic targets and as potential drugs. One way to characterize them would be to develop innovative systems using Raman spectroscopy (or FTIR) coupled with X-ray scattering to study in situ the structure of proteins in solution (emulsion) or solid state (lyophilized powder) while having the ability to optimize the operating conditions (P, T, pH, ...).

Specific instrumental device :
• Transmission Mode with a Cu tube (lambda = 1,54 Å - E = 8 keV)
• An Inel CPS120 curved detector for WAXS measurement +
     a 2D detector or an Inel linear detector for SAXS measurement 
• In situ reaction with a heating hot jet or/and heating cold jet

Set up for combined SAXS / WAXS / Raman spectroscopy
