ABSTRACT:
In a liquid chromatography apparatus, a stream of fluid flows at uninterruptedly high-pressure through a valve structure into a chromatographic column. The valve structure comprises an entrance port and a check valve through which a quantity of sample fluid can be introduced into the high-pressure carrier fluid stream. The entrance port of the valve structure is configured to mate in leak-tight sample fluid communication with an exit port on a high-pressure sample fluid delivery device. In a preferred embodiment, the high-pressure sample fluid delivery device is configured as a hand-gun, with a piston disposed in the barrel thereof to eject a quantity of sample fluid from the muzzle thereof. In this embodiment, the barrel of the gun is received within the entrance port of the valve structure so as to form a high-pressure seal.
