Name
NWA 4968 pellet
Date

Thickness
500.0 $\pm$ 100.0 ${\mu}m$
Diameter
13000.0 ${\mu}m$
Mass
0.13 $\pm$ 0.02 $g$
Substrate material
pressed powdered polyethylene glycol powder
Comments
The pellet was prepared by pressing (7 tons for 5 min) about 130 mg of the powdered material (grain size 1–75 µm) on top of a powdered polyethylene glycol (PEG) substrate pellet. The PEG is used as a substrate to avoid pellet break. Thickness of the meteorite pellet is large enough (>500 µm) to avoid contribution of PEG to the spectra.
