| Abstract: |
| A new control system was designed for fast gas chromatography(FGC) in this paper.The controller is mainly composed of the column temperature control system，automatic sampling and pressure control system of the gas path.The range of temperature control is from 30 to 160 ℃，the heating rate approximates 3 ℃/s，the temperature control accuracy is about ± 0.5 ℃，and the carrier gas pressure control range is from 0 to 0.5 MPa.Applying the controller in homemade FGC，a standard sample composed of straight-chain n-alkanes(C1-C8) and toluene was tested by the FGC.The result indicated that the 9 species could be completely separated in 100 s. |
