High-throughput high-pressure small-angle neutron scattering sample cells and environments

A high-throughput, high-pressure (HT HP) sample cell for connection to a pressure system for measuring radiation scattering of a soft matter liquid sample under pressure, the sample cell comprising:

• (a) a pressure transmitter chamber comprising a compressible, circular internal separator member;
• (b) an enclosure comprising:
• (i) a top cell member comprising a first outer surface, a first inner surface, and a circular beam recess in the first outer surface and oriented perpendicularly to the first outer surface and first inner surface, wherein the circular beam recess comprises a beam entrance window;
• (ii) a bottom cell member comprising a second outer surface, a second inner surface, a circular sample recess in the second inner surface and oriented perpendicularly to the second outer surface and second inner surface, and a pressure fluid delivery hole, wherein the circular sample recess comprises a beam exit window;
• (iii) a pressure fluid inlet port for connecting the sample cell to a supply of pressurizing fluid and in fluid communication with the pressure fluid delivery hole for delivering the supply of pressurizing fluid to the circular sample recess;
• and
• wherein the compressible, circular internal separator member is disposed within the circular sample recess and makes contact with the beam exit window, wherein the compressible, circular internal separator member is configured for receiving a soft matter liquid sample and for applying compression to the soft matter liquid sample when pressurized fluid is delivered to the circular sample recess.
