Gas and electrical feedthroughs are in the closure plug, and these plugs can be customized to suit individual experiments. The large volume of this experimental apparatus allows tremendous flexibility in experimental design. The ability to incorporate numerous electrical feedthroughs into the high pressure environment provides expanded potential for in-situ measurements of chemical and physical properties at pressure and temperature. Furthermore, because the pressure medium is a gas, pressures can be measured accurately, and one can be assured that the pressure experienced by the sample is entirely isotropic. Schematic representation of high-pressure plumbing.
Green sections contain up to tank pressure.
Light blue sections contain up to 207 MPa. Dark blue sections contain up to 1.03 GPa. Hydraulic oil represented in red. Any mixture of gasses can be used for the pressure medium, subject only to limitations of freezing pressure, and material compatibility. Oxygen and hydrogen fugacities can be controlled with solid buffer materials, or using the hydrogen membrane technique.
