Fluid oscillator analyzer and method

Claim 1

IN A CHROMATOGRAPHIC ANALYSIS SYSTEM WHEREIN A FLUID SAMPLE TO BE ANALYZED IS INTRODUCED INTO A CHROMATOGRAPHIC COLUMN, AND A CARRIER GAS IS DIRECTED THROUGH THE COLUMN TO ELUTE THE CONSTITUENTS OF THE FLUID SAMPLE; APPARATUS FOR DETECTING THE ELUTED CONSTITUENTS COMPRISING FIRST AND SECOND DETECTORS, EACH COMPRISING MEANS FORMING A FLUID PASSAGE, MEANS TO DIVERT FLUID AT THE OUTLET OF THE SAID PASSAGE INTO SECOND AND THIRD STREAMS, MEANS TO RETURN A PORTION OF SAID SECOND STREAM TO SAID PASSAGE IN A DIRECTION SO AS TO TEND TO DIVERT A GREATER PORTION OF THE FLUID IN SAID PASSAGE INTO SAID THIRD STREAM, AND MEANS TO RETURN A PORTION OF SAID THIRD STREAM TO SAID PASSAGE IN A DIRECTION SO AS TO TEND TO DIVERT A GREATER PORTION OF THE FLUID IN SAID PASSAGE INTO SAID SECOND STREAM; MEANS TO DIRECT THE EFFLUENT FROM THE COLUMN THROUGH THE FLUID PASSAGE OF SAID FIRST DETECTOR; MEANS TO DIRECT A STREAM OF REFERENCE CARRIER GAS THROUGH THE FLUID PASSAGE OF SAID SECOND DETECTOR; A FIRST VIBRATION SENSING MEANS POSITIONED ADJACNET SAID FIRST DETECTOR; A SECOND VIBRATION SENSING MEANS POSITIONED ADJACENT SAID SECOND DETECTOR; AND MEANS CONNECTED TO SAID FIRST AND SECOND SENSING MEANS TO MEASURE THE DIFFERENCE BETWEEN THE FREQUENCIES OF THE VIBRATIONS RECEIVED BY SAID FIRST AND SECOND SENSING MEANS.
