Identification methods of organic materials

Process:

Organic compounds are composed of several molecules. The process of chromatography allows to separate the molecules from each other and identify them separately with a mass spectrometer.

Applications:

Allows the chemical analysis of a complex mixture. Specific application on binders’ identification (oils, resins, glues, etc.)

Process:

When matter is under an infrared beam light of a known wave length, it is possible to measure the absorption of the irradiation by the matter. This measurement allows to identify the chemical bonds in the studied material and deduce the components of the matter.

Applications:

Characterisation of organic materials. Specific application on binder identification (oils, wax, resins, polymers, glues, etc.).

Process:

Specific coloring of proteins and lipids in contact with dyes.

Applications:

Allows to detect presence of proteins or lipids on a paint layer and gives information about the nature of the binder used.

Process:

A monochromatic light beam is directed onto the material surface. The scattered light is analysed. It gives information about the material structure and the molecular composition.

Applications:

Identification of weathering products, mineral and organic pigments, etc.
