Compliance control

Conformity testing verifies that a material or product meets the expected technical, regulatory, or quality specifications. This analysis relies in particular on Fourier transform infrared (FTIR) spectroscopy, also known as FTIR, a reference technique for identifying the chemical composition of a material, detecting anomalies, comparing batches, or revealing non-conformities related to raw materials, additives, or the manufacturing process. This type of testing is essential for the packaging, materials, and polymers sectors, as well as for cosmetics and technical formulations.

Importance of control

A non-compliant product can lead to malfunctions, regulatory risks, or performance defects. Conformity control verifies the material's identity, detects unintentional or fraudulent substitutions, identifies contaminants or undeclared additives, and compares a sample to a certified reference. In the polymer and packaging industry, it ensures the verification of raw materials upon receipt, the monitoring of production batches, and the control of chemical composition throughout the manufacturing cycle. In cosmetics, it confirms the actual composition of a product and guarantees the integrity of the ingredients used.

Analytical methods

FTIR spectroscopy is a particularly powerful technique for analyzing the molecular structure of materials. It allows:

• to identify the polymers (PE, PP, PET, PVC, etc.)
• to detect the presence of additives, mineral fillers, plasticizers or stabilizing agents
• to analyze residues, impurities or contaminants
• to compare a finished product to a reference spectrum to validate its conformity

FTIR can be used in various modes: transmission, ATR (Attenuated Total Reflectance), and reflection, allowing the analysis of solid polymers, powders, films, resins, lotions, and creams. This approach, complementary to thermal, mechanical, or chemical analyses, provides a clear and rapid view of a material's composition.

Analyzed matrices

Conformity control applies to a wide range of industrial products: cosmetics (creams, gels, lotions), plastics (films, granules, injection-molded parts), additives, mineral fillers, composite materials, printing inks, resins, adhesives, and food or technical packaging. It is suitable for both raw materials and finished products, enabling quick and easy verification of compositional integrity.

Interest for professionals

For manufacturers, distributors, formulators, and processors, conformity control is a strategic step. It ensures production security, prevents the risk of regulatory non-compliance, monitors suppliers, improves traceability, and reduces costs associated with manufacturing defects. It is also used to resolve disputes, analyze product returns, investigate malfunctions or anomalies, and verify the conformity of imported materials. R&D laboratories use it to compare prototypes, validate innovations, and optimize their formulations.
