We set up analytical methods for the control of raw materials before manufacturing. We also ensure the conformity of the products (intermediate or finished products).
Determination of impurities
Impurities present in a product can impact its performance and lead to non-conformities. Our analytical department is able to identify and quantify liquid, volatile or solid impurities. We also propose to purify the product thanks to our distillation, separative chromatography, diafiltration, freeze-drying equipment…
Development of analytical methods
PolymerExpert relies on its experience and on existing standards to develop analytical methods and propose reliable and robust analytical protocols. Each new method is validated according to the following criteria: specificity, repeatability, accuracy, precision, linearity and limits of detection and quantification (LOD and LOQ). A transposition of the analytical method can be performed at the customer’s site.
In a performance improvement approach, PolymerExpert proposes to separate, identify and quantify the different constituents of numerous formulations: resins, paint, varnish, antibiotics, forging products, elastomers, glues… We can suggest formulation modifications to reach precise specifications. Thanks to our Formulation department, we can also take care of the reformulation of products.
Expert in case of litigation
In case of customer complaints or disputes, we combine our knowledge with analytical results to determine the cause of the non-conformity. PolymerExpert provides technical and numerical evidence in a precise and understandable report. Corrective or preventive actions are proposed and can be tested both in the laboratory and in the field.
Understanding of reaction mechanisms
In case of change of supplier, protocol, or material, we can determine the impact of these parameters on the final product. We match relevant characterizations with the performance results of your product to advise you on the new process.
We rigorously adapt to the needs of our customers and offer them a tailor-made support. PolymerExpert has expertise in many types of analysis, such as:
Chemical compatibility tests of materials in liquids (solvents, acid, base, …)
Characterization of the transparency or the color (L,a,b) of a solution or a material
Characterization of aqueous solutions: pH, osmotic concentration, refractive index, dry matter
Analysis of particle size distribution (dry or liquid route): number of populations, size distribution in volume or in number (D(10), D(50) and D(90)
Evaluation of surface tension (hydrophilicity, hydrophobicity)
All polymer families can be characterized by PolymerExpert (polyurethane, polyacrylate, PET, PP, PE, fluorinated polymers, polyamide, polyamine…). We analyze different types of polymers (homopolymers, copolymers, tri-blocks, branched polymers…). Samples can be analyzed in solution, in the form of materials or granules.
Thermoplastic and thermoset composites can be analyzed by our laboratory.
We can analyze the constituents of complex formulations such as resins, paints, varnishes, forges, rubbers, plastic packaging, adhesives, antibiotics, cosmetics, coatings (mono and multilayer)…
