All chemical analyzes of the materials are strictly carried out on the basis of national and international regulations (ASTM, UNI, DIN, etc.) and on specially prepared internal procedures.

The analysis of metal alloys occurs through three main methodologies:

• Traditional wet chemical analysis;
• Quantum chemical analysis (SEO Optical Emission Spectroscopy);
• PMI – Positive Material Identification.

In the wide range of composite materials, CTS performs:

• determination of the type and percentage of reinforcement (glass, kevlar, carbon fibers, etc.) and of the density of resin-based composite materials (fiberglass, etc.);
• density determination;
• FTIR spectrometry to evaluate the chemical characteristics of the organic component of the composite;
• DSC analysis on polymeric materials to evaluate Tg and resin cross-linking degree.

The analysis of oils and lubricants is performed in order to evaluate their characteristics, establish a classification and is a useful tool in the case of failure analysis.

The parameters that are typically determined are:

• Viscosity;
• Water content;
• Hydrocarbon content;
• Percentage of ashes;
• Insoluble content;
• Evaluation of the degree of particle contamination according to NAS code 1638 and according to ISO 4407;
• TAN;
• TBN;
• Presence of dissolved metal materials;
• Flash point in a closed vase and open vase;

Our corrosion analysis:

• Corrosion tests on metallic materials.
• Accelerated aging tests.
• Salt spray chamber tests on metallic materials and protective coatings.

• FTIR analysis on polymeric materials;
• DSC analysis on polymeric materials for measuring melting temperature (Tm), glass transition temperature (Tg) and degree of cross-linking (thermosetting resins / polymers).

What information is obtained:

Following DSC analysis of polymeric materials, physical and chemical properties of the sample are determined according to temperature or time:

• melting temperature (Tm);
• degree of crystallinity;
• glass transition temperature (Tg);
• specific heat;
• reaction heat.
