MVA Scientific Consultants is a contract testing laboratory that specializes in material testing services. In our 26+ years of experience in material testing, our scientists have dealt with a wide variety of materials including polymers, coatings, paints, metals, fillers, minerals, composites, pharmaceutical ingredients, solvents, contaminants, impurities and unknowns.
At MVA Scientific Consultants, we offer microscopy and spectroscopy capabilities to characterize different materials. Our material scientists have knowledge and experience in a wide range of industries including aerospace, automotive, chemical, oil and gas, polymers and plastics, packaging, adhesives, medical devices, textiles and apparel, building materials, electronics, composites, consumer products and nanomaterials.
Electron Microscopy Material Testing and Characterization
Scanning electron microscopy (SEM) is one of the most important and versatile techniques for material testing and characterization.
SEM offers high resolution imaging capability and when coupled with energy dispersive x-ray spectroscopy (EDS), it provides pinpoint elemental composition for material analysis.
With advanced application, it can also perform elemental x-ray mapping.
Transmission electron microscopy (TEM) is useful for testing and characterizing different materials at a near-atomic level, including polymers, nanoparticles and coatings.
TEM is especially useful for characterizing copolymer blends to see how well the different polymers are mixed.
In addition, TEM can achieve much higher resolution then SEM, which makes it a valuable technique for nanoparticle size distribution measurement.
Molecular Spectroscopy Material Testing and Characterization
Raman spectroscopy is useful for characterizing materials including nanoparticles, active pharmaceutical ingredients and raw materials, polymers, coatings, and impurities. Raman spectroscopy gives molecular structure and crystallinity information on a material. When coupled with Raman chemical imaging, it can provide molecular information on a pharmaceutical formulation for tablets, stents, inhalants, and different layers of coatings in a packaging material.
Fourier transform infrared spectroscopy (FTIR) is one of the most robust techniques for material testing. It is extremely useful for material identification and analysis of molecular functional groups.
Material Surface Testing and Characterization
Surface measurement, also known as surface metrology, refers to the measurement of topography or surface roughness of precision surfaces. Interference microscopy is a non-contact optical profilometry technique used to obtain three-dimensional images and quantitative measurement of surface texture or “roughness.”
Surface measurements include surface shape, surface finish, surface profile roughness, surface texture and structural characterization. Surface roughness and the details of the surface profile determine the performance and appearance of many products. The roughness or texture of a part is important for a surface’s suitability in different applications.
With over 26 years of experience, MVA Scientific Consultants has solved over 11,000 interesting and challenging problems.
