Fourier-transform infrared (FTIR)

Description

The Fourier-transform infrared (FTIR) spectrometer utilizes broadband IR radiation to probe the vibrational modes of molecule in a liquid, powder, bulk, or thin film sample. The structural features of a molecule and its functional groups produce a characteristic and reproducible absorption in the IR spectrum and can be analyzed to yield both qualitative and quantitative results. This equipment features a robust solid-state IR source, temperature stabilized detector, and permanently aligned interferometer for long term measurement stability. It also includes quick-change sampling modules for added extensibility.
