ABSTRACT:
A method and apparatus for fluid sample injection for a chromatograph using an acoustic or sonic generator generating standing waves in a hollow tube. A selectively controlled source of a carrier fluid is arranged to apply a carrier fluid to one end of the tube. A source of sample fluid is connected by a valve to a predetermined location along the tube corresponding to the location of a node separation space in a standing wave generated by the acoustic signal generator. A sample exit port is located on the other side of the hollow tube and is controlled by a valve to provide an exit for the sample fluid flowing across the hollow tube between the nodes. Another end of the tube that is connected to a chromatographic column to supply the sample thereto for separation and subsequent application to a chromatographic detector. A timing and control circuit is used to control the frequency and amplitude of the acoustic signal generator and the timing of the operation of the carrier gas and sample control valves.
