Bruker Tensor 37 FTIR
The Bruker Tensor 37 is a new 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.
The system includes a Diffuse Reflectance attachment, and a Horizontal Attenuated Total Reflectance attachment. The HATR has Ge flat-plate and trough cells, and a ZnSe flat-plate cell. 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 Tensor 37 instrument is located in 1238 Hach Hall. Enquiries should be directed to Brett Boote. Phone 515-294-5975 (office). Since the FTIR is a shared component of the TGA-DSC system, please reserve time on the TGA-DSC calendar.
This instrument is used by students and other researchers. Staff will provide training and some basic methods development assistance. The hourly rates are listed below. NOTE: There is a minimum billable increment of one-half hour.
