Description
MIR spectra of several matrix grains of GRA95229 at different temperature, under vacuum
Variable(s)
spectrum type, chemical variability
Number of spectra
10
Instrument
Brucker Vertex 70 + Hyperion 3000
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.
