Characterization

Netzsch Pulse-TGA/DSC-MS

The Netzsch TGA/DSC instrument offers simultaneous thermogravimetric and differential scanning calorimetry measurements. It is coupled to a mass spectrometer (MS) analysing the evolved gases and a pulse system for controlled gas delivery. It is meant to characterize solid catalysts in terms of loss on ignition (LOI), coke quantification and temperature programmed reduction/oxidation/desorption.

The main features of the Netzsch TGA-MS-DSC are:

Temperature from 0 °C to 1000 °C.
Weighing up to 35000 mg with a resolution of 0,1 μg over entire weighing range.
DSC resolution of < 1 μW.
Vacuum-tight oven with automated evacuating system and vacuum down to 10^-3 mbar
Simultaneously TGA data (thermogravimetric analysis) and DSC data (differential scanning calorimetry) in one measurement.
Option of adding flow or pulses of gases (O₂, H₂, CO, NH₃) to perform TPO, TPR, TPD, etc.
The identity of gases evolved during the heating process can be determined by MS detection.
The system is fully automated and includes a 20-position sample carousel.
Various purge, evacuation, and fill cycles available to remove air and moisture from the sample area.
