Physical characteristics

Thickness: 300.0 $\pm$ 100.0 ${\mu}m$
Diameter: 13000.0 ${\mu}m$
Mass: 0.1 $\pm$ 0.02 $g$
Substrate material: pressed KBr powder
Substrate comments: The KBr substrate is ~ 2 mm thick and 13 mm in diameter. It was formed by pre-pressing powdered KBr into a pellet. KBr is used as a substrate to avoid meteorite pellet break.
Comments: Pellet prepared by pressing (7 tons for 10 min) about 100 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.
