DSC Pressure Cell
The Pressure DSC (PDSC) cell is a DSC cell enclosed in a steel
cylinder that can be pressurized to 7 MPa (1000 psig). In addition
to performing the same measurements as the DSC cells, it can
operate at elevated pressure or under vacuum. This ability to
vary pressure as well as temperature provides the following:
• Resolution of overlapping peaks
• Determination of heats of vaporization and vapor pressure
• Reaction rates in controlled atmospheres
• Studies of pressure-sensitive reactions
The Pressure DSC cell has two gas flow control valves, a three-
way valve, a pressure gauge, a pressure release valve, and gas
pressure fittings on the side. The cell has a pressure transducer
which continuously measures actual sample pressure and stores
it in the data file.
This cell is optional for the Q2000 and Q1000. It comes standard
on the Q20P and Q10P.
