- Description
- MIR spectra of several matrix fragments of DOM 08006, MIL 07687, LAP 031117, DOM 03238, and Kainsaz CO chondrites under vacuum and at ambient temperature, 100°C and 300°C
- Number of spectra
- 68
- Variable type(s)
-
- sample composition
- chemical variability
- temperature
- Instrument
- Brucker Vertex 70 + Hyperion 3000 – micro-transmission Mid-IR
- Sample holder
- The diamond windows were loaded into a cell, enabling temp. up to 300C under vacuum (from 10-4 mbar down to 10-7 mbar). Optical access is permitted from both sides of the cell through KBr windows, thus enabling measurements in transmission.
