Fourier Transform Infrared Spectroscopy (FTIR) is a spectral analysis technique used to identify chemical bonds. It can be used to investigate existing chemistry, track chemical bonds through a process, or identify unknown materials. Typical samples can be liquids, solids, powders or even gases. Sample size can be as small as several µL.
The Hyperion is a high performance infrared microscope with transmission, reflection, grazing incidence, and Attenuated Total Reflectance (ATR) acquisition modes. Spectral acquisition area can range from ~250 µm² to as small as ~10 µm². Motorized sample stage enables spectral mapping, though signal strength decreases as spatial resolution increases. Spectral mapping allows investigation of spatially resolved gradients and distribution of chemical species across a surface. Transmission is the standard mode of acquisition though samples need to be sufficiently thin (< 50 µm) to allow good signal to noise.
