Ventacon Cold Cell Systems allow users to record
Raman spectra of solids, semi-solids and liquids at temperatures down to -150ºC. With the
Ventacon heated probe the temperature of the specimen can be controlled to within +
2ºC at the value of your choice over the same range vis room temperature to
-150ºC.
Low temperature Raman cells have been reported based
on a variety of technologies. Thus, cooling can be achieved using
Peltier solid-state cooling devices or liquid refrigerants. The most
familiar incorporates a 'cold finger' surrounded by an evacuated jacket
or the sample is suspended in a stream of gas boiling off from a remote
liquid nitrogen container. The problem with all of these is that they
require services - water cooling and evacuation for the Peltier devices,
evacuation for the cold finger cells and, of course, large diameter
insulated tubes for the cells based on liquid nitrogen 'boil-off'.
As a result it is difficult or impossible to operate these cells in
a contemporary Raman sample area with the lid closed.
