Description
MIR spectra of IOM extracted from a series of 20 CM and C2-ungrouped chondrites with the CF/HCl technique at IPAG and DTM, under vacuum and at low temperature
Variable(s)
sample composition
Number of spectra
20
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 or ZnS windows, thus enabling measurements in transmission.
Standard medium
air
