ATR-FTIR Spectroscopy
Attenuated total reflectance (ATR) is the most widely used sampling methodology for Fourier transform infrared (FTIR) spectroscopy. ATR-FTIR quickly and easily measures a broad range of sample types, including liquids, solids, powders, semisolids, and pastes. Learn about how ATR-FTIR works, the different types of ATR sampling accessories available, and their applications.
Learn MoreTransmission FTIR Spectroscopy
Transmission FTIR mode is suitable for liquids, gases, powders, and films. Learn about how transmission FTIR spectroscopy works, the different types of transmission FTIR sampling accessories available, and their applications.
Learn MoreReflectance FTIR Spectroscopy
Reflectance FTIR is used to acquire high quality spectral data from solid samples. Specular reflection is used with reflective surfaces, diffuse reflection (DRIFTS) works with rougher, less reflective surfaces (often powders), and reflection-absorption grazing angle FTIR measures sub-micron thin films and contaminants on surfaces.
