Figure 1 shows the state when pressurizing the inside of the vial with the multiple head space extraction device according to this invention, and Figure 2 shows the state in which the sample pressure in the gas-tight syringe is brought to atmospheric pressure equilibrium and then transferred to the gas chromatograph sample introduction section. It shows the state just before introduction, and the third
The figure shows the gas-tight syringe 2 and the vial 1 in an open state in order to make the pressure in them the same as the atmospheric pressure. Figure 4 shows the state in which the inside of the vial is pressurized when a sample in a vial is introduced into the sample introduction part of a gas chromatograph using the conventional method, and Figure 5 shows the state in which the vial is pressurized when the sample is introduced into the sample introduction part of a gas chromatograph using the conventional method. FIG. 6 shows a state in which a sample is introduced, and FIG. 6 shows a state in which sample gas is discharged into the atmosphere in order to equalize the pressure inside the vial with the atmospheric pressure. FIG. 7 shows the difference in peak area when the same sample is analyzed using a gas chromatograph using a conventional method and when the analysis conditions are changed. 1...Sample storage vial, 2...Gas-tight syringe, 3...syringe needle, 4...plunger, 5...
