Powder X-ray diffraction
Supplier: Bruker AXS
Principle: The -theta/-theta geometry (inverted Bragg-Brentano geometry) of this apparatus permits in-situ analysis of solid phase in suspension in a liquid phase (reactor capacity is 100 mL), or solid phase in equilibrium with its vapor.
Type of analyses performed: This aparatus is suited for in-situ monitoring of solution crystallization processes: the reactor temperature (from -30 to 70 °C) and solvent injection are controlled during the process et the system analyzes the nature of the solid phase in suspension. This allows for instance to determine temperatures of phase transition or peritectic temperatures (solvation, desolvation). In a nutshell, detection of efflorescent solvates is made easy with In-SituX.

Principle: X-ray diffraction analyses (in reflexion mode / Bragg-Brentano geometry) of powdered samples. The sample holder is equipped with a spinner than reduces texture and preferiental orientation effects.
Supplier: Bruker AXS
Principle: X-ray powder diffraction analysis of crystalline samples in theta theta geometry (Bragg Brentano geometry). The sample holder can be thermostated with a TTK450 Anton Parr heating chamber linked to a liquid nitrogen cooling stage (temperature range: -150°C up to 250 °C). This system is equipped with a copper anode, Ni filter, and a high performance LynxEye® detector
Type of analyses performed: This device allows to follow the evolution of the crystalline phase according to the temperature, and therefore to determine, for examples, the temperature transition of a solid solid transition or of a desolvation process. Therefore, these data are of main interest for the construction of a phase diagram.

Supplier: INEL
Principle: X-ray powder diffraction analysis of crystalline samples (asymmetrical reflexion geometry). The system is equipped with copper anode, and curved detector that allows to analyse on a large range on 2theta in one “shoot” (from 3° up to 110°).
Type of analyses performed: This apparatus allows the routine anlysis of crystalline powder sample, and can also be equipped with a 6 position sample holder.
Single Crystal X-ray diffraction
Supplier: Bruker
Principle: Single crystal diffraction analysis to achieve the structural resolution of crystalline solid.
- Two last generation micro-sources with air cooling, limiting the ecological impact of the device
- One copper micro-source « IμS 3.0 » and one Molybdenum « IμS diamond TM», which allows the determination of absolute configurations even without "heavy" atoms in the molecule, or without a known stereogenic center.
- 4 circles goniometer with motorised Kappa turntable for detector with optical encoder.
Type of analyses performed: The system is equipped with a temperature regulator that allows the data to be recorded at low temperature (from room temperature down to 150K).
