description The invention discloses a GC chromatographic analysis method of conjugated fat olefin aldehyde and ketone compounds and belongs to the technical field of analytical chemistry. The gas chromatographic detection conditions of the GC chromatographic analysis method are that for a gas chromatograph, the detection temperature of a hydrogen flame ion FID detector is 200-250 DEG C, and the sample injection port temperature is 150-250 DEG C; for a chromatographic column: the column temperature is first set to be 40-80 DEG C and is kept for 5-20 minutes, then the column temperature is then set to be180-250 DEG C and is kept for 5-30 minutes; carrier gas is nitrogen or helium gas, the flow rate of carrier gas is 1-10 ml/min, the pressure of the carrier gas is 0.02-0.08 MPa; the pressure of the hydrogen gas is 0.02-0.06 MPa; air pressure is 0.04-0.08 MPa; the split ratio is 1:100 to 1:25. The GC chromatographic analysis method improves the working efficiency and the sample separation degree and reduces the testing cost.
