Bruker Tensor 37 FTIR
The Bruker Tensor 37 is an FTIR purchased as part of the TGA/DSC-IR/MS system. It is avaialble for use when TGA/DSC measurements are not scheduled which utilize FTIR. 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 TGA/DSC-evolved gases) is available for use.
The system includes modules for Diffuse Reflectance, a Horizontal Attenuated Total Reflectance (HATR) attachment, and a recently purchased diamond ATR. 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); though a pellet press and a salt plate polishing kit are available in the instrument lab (1240 Hach).
The Tensor 37 instrument is located in 1238 Hach Hall. Enquiries should be directed to Brett Boote. Phone 515-294-5975 (office). FTIR users will also be given access to the TGA calendar to monitor concurrent reservations.
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.
