PRESSURE CYCLING SYSTEMS AND RELATED METHOD

摘要

A pressure cycling system includes a reaction chamber configured to receive a sample and a charge pump in fluid communication with the reaction chamber. The charge pump is operable to convey a fluid from a fluid source toward the reaction chamber. The system also includes a check valve disposed between the charge pump and the reaction chamber. The check valve is operable to inhibit the flow of fluid from the reaction chamber toward the charge pump. A pressure intensifier is in fluid communication with the reaction chamber. The pressure intensifier is pneumatically operable to adjust a pressure in the reaction chamber. A controller is configured to control operation of the charge pump and the pressure intensifier. The controller is configured to pressurize the reaction chamber to a first pressure through operation of the charge pump. The controller is also configured to fluctuate the pressure in the reaction chamber between a second pressure and a third pressure through operation of the pressure intensifier.
