For Fourier transform infrared (FTIR) chemical imaging analyses, Thermo Fisher Scientific Inc. has released an imaging attenuated total reflectance (ATR) accessory with enhanced spatial resolution and high-speed data acquisition capabilities. It is designed to integrate with the company’s range of FTIR microscopes to perform chemical imaging of challenging samples. This is of benefit to manufacturers of composite structures, paper products, pharmaceutical dosage forms, biological tissues, polymer films and coatings. The accessory requires the sample to be compressed only once against an extended area of contact. Data collection may then proceed at the same speed as normal transmission or external reflectance experiments. The accessory simplifies the task of obtaining high-quality infrared spectra in cases of samples that are difficult to prepare for transmission analysis.
