Title:
圧縮性流体を広い圧力範囲にわたって動的に補償するための圧縮性流体のポンプシステム
Document Type and Number:
Japanese Patent JP5286412
Kind Code:
B2
Abstract:
An invention is claimed that enables the pumping of compressible fluids at high pressures when an accurate flow is desired. Two pressure sources, for example pumps plumbed in series, separate thermodynamic work, such as pressurization, at the first pressure source from a volumetric or matter metering function in the second pressure source. One example is a flowstream delivery for a chemical instrumentation system that is manufactured from relatively unsophisticated pumps yet delivers precise flows with low pulsation (<1%) over pressures greater than 100 bar. An advantage of one embodiment allows the economical conversion of typical HPLC systems to state of-the-art supercritical fluid chromatography (SFC) systems with minimal modification to system components.
