The GCM has numerous devices to characterize the different materials properties. In general, it’s possible to classify these techniques in four large categories:
A chemical analysis aim to obtain the sample’s elementary or molecular composition. Different techniques allow to obtain qualitative, semi-quantitative or quantitative results and to analyze liquids, solids and/or gaz. More information is available on the Chemical Analysis page as well as on each different technique’s page.
A microscope allows imaging a small sample’s section. Enlarging can tremendously vary from one technique to the other, going from less than a 100 times for a standard optical microscope, to hundreds of thousands of times for an electronic microscope or an AFM. Certain techniques also allow obtaining quantitative elements on the sample’s topography (roughness, micro-geometry).
Thermal analysis study physical and chemistries sample’s properties by subjecting them to temperature variations (heating or drop in temperature). The GCM has the two most common techniques: thermo-gravimetric analysis (TGA)and differential scanning calorimetric (DSC).
The mechanic properties include the parametric range that describes the material performance under a charge (hardness, bouncing limits, traction resistance, ductility, resiliency, adhesion strength). The GCM dispose of a vast equipment’s range that make possible measuring massive materials, beams and even nanometric films.
