Pressure injection apparatus and method for injecting a sample into an electrophoresis capillary |
摘要 |
A present invention and method provides a pressure injection apparatus (20) that injects a quantitatively defined volume of liquid sample (21) from a container (22) into a capillary device (23). A servo pressure primary regulator (26) is included which precisely regulates the fluid from a supply pressure (PS) to a substantially constant regulated pressure (PR) in communication with the liquid sample (21) for a predetermined period of time. A feedback mechanism cooperates with a valving assembly (31) to continuously monitor and adjust the regulated pressure (PR) to be substantially constant and precise for delivery to the container (21).
