- Substrate comments
- KBr substrate ~ 2 mm thick, 13 mm diameter. The KBr is used as a substrate to avoid meteorite pellet break.
- Comments
- Pellet prepared by pressing (7 tons for 6 min) 104 mg of the original dust (grain size 1–100 µm) on top of a KBr substrate pellet. The KBr is used as a substrate to avoid pellet break. Thickness of the meteorite pellet is large enough (>200 µm) to avoid contribution of KBr to the spectra.
