Abstract: The present disclosure relates to phase detection in multi-phase fluids where two fluid phases can be present in the fluid. Phase detection apparatus and methods are disclosed for determining the phase(s) (e.g., supercritical, liquid, and/or gas) of a fluid in a multi-phase fluid system, such as carbon dioxide based separation and chromatography system.

Abstract: The invention generally provides a dynamic back pressure regulator. In an exemplary embodiment, the back pressure regulator includes an inlet, an outlet, a seat disposed between the inlet and the outlet and defining at least part of a fluid pathway, and a needle displaceable relative to the seat to form a restriction region therebetween for restricting fluid flow between the inlet and the outlet. In some embodiments, the needle can include a corrosion and/or erosion resistant polymer tip.
