Vacuum Systems

The AHIIA system was built in 2013 . This system is a vacuum chamber (10-9 mbar) with a cryogenic head providing a temperature control from 12 K to 310 K.

A FT-IR spectrometer is coupled to the vacuum chamber providing an in situ analysis of samples formed on the sample holder connected to the cryogenic head.

A residual gas analyzer mass spectrometer is also coupled to the vacuum chamber to analyze gas phase compounds of the vacuum chamber.

The vacuum chamber is also linked to the VAHIIA system, a GC-MS, through a homemade interface providing the transfer of gas phase compounds of the vacuum chamber to the GC-MS.

A rod system allows to recover sample holder from the cryogenic chamber under vacuum and to store them in vacuum before their ex situ analyses.
