Instrument #1
Instrument
Brucker Vertex 70 + Hyperion 3000 – micro-transmission Mid-IR
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.
