Bard Hall B56
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 in some cases identify materials. Typical samples can be liquids, solids, powders, or even gasses and sample size can be as small as several µl.
The Hyperion is a high performance infrared microscope with transmission, refelection, 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 strengths are reduced as spatial resolution is increased. 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.
Low temperature operation
With the use of a cryostat, FTIR spectra can be acquired, in the tensor sample compartment, in transmission, across a wide range of temperatures from 4.2 K to 500 K. Cryostat operation is possible with Liquid Helium but also with Liquid Nitrogen for more convenient and economical testing above 77 K. The cryostat also features an electrical feedthrough with 10 solder studs for electrical connections to a sample or chip. Please contact the facility manager for more information regarding this capability.
