Abstract
In a chromatographic analysis system, carrier fluid containing a sample fluid and pure carrier fluid are alternately supplied to both first and second fluid inlets of a chromatographic detector. Lock-in detection of the output of the chromatographic detector based on the frequency at which the carrier fluid containing a sample fluid and pure carrier fluid are alternately provided to both of the fluid inlets of the chromatographic detector provides a significant signal-to-noise improvement in the chromatograph.
