Netzsch DSC/TGA - MS/IR
Netzsch STA449 F1
This instrument simultaneously provides TGA data (thermogravimetric analysis) and DSC data (differential scanning calorimetry) in one measurement. The furnace is programmable to 1500 C. In additon, the identity of gases evolved during the heating process can be determined by IR (infrared) and MS (mass spec) detection. The system is fully automated and includes a 20-position sample carousel. Various purge, evacuation, and fill cycles are available to remove air and moisture from the sample area. A special oxygen-scrubbing device can also be incorporated when there is zero tolerance for O2 in the system.
The system also includes "Pulse TA" hardware to allow gases to be dosed in to calibrate the IR or MS responses, or to allow specific reactions at high temperature.
Four software packages are included with the system:
- Proteus - DSC/TGA control; acquisition and processing of DSC, TGA, and MS data
- Aeolos - MS control; triggered acquistion and limited processing of MS data
- OPUS - FTIR control; triggered acquisition and processing of IR data
- NIST - MS library and associated search software; processes MS spectra exported by Proteus
Please read CIF document #1 and #3 before requesting training for DSC/TGA measurements. If you wish to analyse the evolved gases, please also read documents #5, #6, and #7 before scheduling your training.
For training, please contact Steve Veysey (email@example.com), 294-5805, 1234 Hach Hall. Use "Booked" to schedule the instrument. Reservations must be approved.
This instrument is intended for student operation. Samples may not be submitted for analysis. The rates listed below do not include the cost of crucibles or FTIR-cryogens, or specialty gases other than the default high-purity argon and nitrogen. Only data acquisition time is billed. Data processing can be performed on the instrument at no charge if time is available, but there is also a separate computer that can be used for processing without charge. Alternatively, Proteus, OPUS, and NIST can be loaded on university-owned computers for exclusve processing of data acquired on this instrument.
|User Category||Instrument Charge||Staff Assistance|
|ISU Researchers||$15 / hour||$30.00|
|Non-ISU academic researchers||$22.50 / hour||$45.00|
|Non-academic users||$45 / hour||$90.00|
