FTIRmittalaitteilla

FTIRmittalaitteilla, also known as Fourier Transform Infrared Spectroscopy with Attenuated Total Reflectance, is a powerful analytical technique used to identify and study the chemical composition of materials. This method combines the principles of Fourier Transform Infrared Spectroscopy (FTIR) with Attenuated Total Reflectance (ATR) to provide detailed information about the molecular structure of samples.

FTIR spectroscopy works by measuring the absorption of infrared light by a sample. When infrared radiation passes through a sample, certain wavelengths are absorbed by the molecules present, creating a unique spectral "fingerprint" for each compound. This fingerprint can be analyzed to identify the functional groups and chemical bonds within the sample.

ATR, on the other hand, enhances the sensitivity and convenience of FTIR analysis by allowing the technique to be applied directly to solid, liquid, or semi-solid samples without the need for sample preparation. In ATR, the infrared light is internally reflected within a crystal, such as zinc selenide or germanium, which is in contact with the sample. The evanescent wave generated at the crystal-sample interface interacts with the sample, providing a strong signal even for thin layers or surfaces.

FTIRmittalaitteilla is widely used in various fields, including chemistry, biology, materials science, and forensic science. It is particularly valuable for identifying unknown substances, studying polymer structures, monitoring chemical reactions, and analyzing the composition of surfaces and thin films. The technique offers high sensitivity, rapid data acquisition, and the ability to analyze a wide range of sample types, making it an indispensable tool for researchers and analysts.
