IR spectrometer

An FTIR spectrometer Bruker Vertex 80v with coupled thermobalance Netzsch Libra F1 is available at the Chair. The device has an external sample chamber for temperature-dependent DRIFTS measurements.

FTIR spectroscopy is an analytical method for the quantitative determination of known substances and for the identification and structural elucidation of unknown substances using reference spectra.

Analysis options:

• FTIR spectroscopy of solids and gases for qualitative material analysis and structure elucidation
• Thermogravimetric analysis for solids with coupled FTIR analysis of the gaseous reaction products
• Investigations in a wide temperature range from -150 °C to 900 °C and pressures ranging from 10^-10 bar to 3 bar
• Time-resolved measurements (step scan / fast scan) for tracking reactions over time
• Heating/cooling and evacuable DRIFTS cell for temperature and pressure-dependent measurements with the option of introducing reaction gas mixtures to track sorption processes (Harrick)
• ATR measuring cell for analyzing solid and liquid samples with diamond crystal (Bruker Platinum)
• Temperature-controlled ATR measuring cell with germanium crystal for analyzing dark samples with high absorptivity (Pike Miracle)
