FTIR analysis helps clients understand materials and products. Analytical testing sample screens, profiles and data interpretation are available on a global basis from our experts who deploy FTIR to identify chemical compounds in consumer products, paints, polymers, coatings, pharmaceuticals, foods and other products. Laboratories with FTIR expertise are located throughout the Intertek global laboratory network.
FTIR offers quantitative and qualitative analysis for organic and inorganic samples. Fourier Transform Infrared Spectroscopy (FTIR) identifies chemical bonds in a molecule by producing an infrared absorption spectrum. The spectra produce a profile of the sample, a distinctive molecular fingerprint that can be used to screen and scan samples for many different components. FTIR is an effective analytical instrument for detecting functional groups and characterizing covalent bonding information.
FTIR can be used with other molecular spectroscopy techniques available in Intertek laboratories, including Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) , Infrared-spectroscopy coupled to Thermogravimetric Analysis (FTIR/TGA), Nuclear Magnetic Resonance Spectroscopy (NMR) , Gas Chromatography - Mass Spectrometry (GC/MS), Liquid Chromatography - Mass Spectrometry (LC/MS), UV/Vis spectroscopy, Near Infra Red (NIR) and Raman scattering. FTIR combined with these techniques provides complementary data regarding a molecule's molecular structure.

AA (Atomic Absorption Spectroscopy)
AA detects the absorption of light to measure the concentration of gas-phase atoms. In general, samples are dissolved into liquid media, and analyzed by the instrument’s sensors. Concentration measurements are determined from a working curve after calibrating the instrument with standards of known concentration. Nanocor scientists use AA to determine the concentration of various metal elements in the montmorillonite to monitor the base mineral quality and purity, essential factors in controlling nanocomposite formation.
