Summary
The Bruker IFS66V is a high-performance research level FTIR capable of performing measurements in the far-IR, mid-IR and near-IR regions at resolutions up to 0.5 cm-1. These various instrument configurations require the use of a range of sources, beamsplitters, and detectors. The instrument is normally configured for routine mid-IR measurements. Other configurations involve staff setup time and must be scheduled in advance with Steve. A long-path gas cell and diffuse reflectance cells are available for use. An older attenuated-total-reflectance cell is available, but researchers must provide their own ATR crystals.
The Bruker Tensor 37 is a newer FTIR purchased as part of a TGA/DSC-IR/MS system. It is avaialble for use when TGA/DSC measurements are not scheduled. The instrument covers the spectral range from 6000 cm-1 to 400 cm-1; maximum resolution is 0.5 cm-1. Fast and repetitive scanning is available on this instrument. A large vapor-phase library (normally used with DSC/TGA-evolved gases) is available for use.
In general, researchers are required to provide their own sampling devices (liquid cells, salt-plates, pellet presses); a student-grade pellet press and a salt plate polishing kit are available in the lab.
The IFS66V instrument is located in 1240 Hach Hall; the Tensor 37 instrument is located in 1238 Hach Hall. Enquiries should be directed to Steve Veysey. Phone 515-294-5805 (office)
