Vibrational Spectroscopy Laboratory

Vibrational spectroscopy for the characterization of polymers and chemical including FTIR, Raman and Near-infrared

Vibrational spectroscopy is a key non-destructive analytical approach that measures the vibrational energy in a compound using various types of spectroscopy analysis techniques. At Intertek, boasting over three decades of expertise, we harness Fourier Transform Infrared (FTIR), Raman, and Near-infrared spectroscopy to drive insight into polymers and chemical systems. We use these techniques to identify polymers and their additives, discern unknown surface contaminants and defects, and comprehend the chemistry behind thermoset polymer curing. Furthermore, we utilize microscopy to identify particulates, fibers, and defects in materials, allowing for a comprehensive characterization of complex systems.

Fourier Transform Infrared (FTIR) spectroscopy, a cornerstone of our analytical arsenal, uses infrared light to scrutinize the properties of solids, liquids, and gases, presenting a spectrum of characteristic bands pivotal for sample identification and characterization. The technique offers a plethora of sampling methods, including Attenuated Total Reflection (ATR), and Infrared Reflection-Absorption Spectroscopy (IRRAS), enabling surface characterization for coatings and contamination. Infrared microscopy aids in analyzing particulates and fibers through various methods, providing valuable insights into material composition.

Raman spectroscopy, another stalwart in our toolkit, facilitates the observation of vibrational, rotational, and low-frequency modes within a system, aiding in the identification of molecules. The technique is instrumental in particle and fiber analysis, measuring composition and thickness of layers in laminated packaging films, and characterizing surface corrosion and contamination. Moreover, FT-Raman spectroscopy allows for the spectral analysis of bulk materials, overcoming challenges posed by fluorescence.

Our team typically incorporate vibrational spectroscopy in a multitude of chemical problem-solving, quality assurance testing, and materials research support for our global clients. Our commitment to precision and excellence empowers researchers and industries to drive insight into the nature and properties of materials and chemicals.
