2. Description of the Related Art In a conventional gas chromatography inlet, a syringe introduction part and a separation column connection part are located in a straight line, and a liner is inevitably an elongated linear glass tube. For this reason, at the time of sample injection, the sample may directly touch the metal surface or enter the column in a liquid state, and in order to prevent this, the liner is filled with glass wool or an inverted cup is provided. . The usual sample injection volume in conventional gas chromatography is several μl. However, several methods have already been proposed for a large-volume injection method in which this is increased to several tens of μl. One of them is an on-column system, in which a pre-column is provided before and after a main column, and a solvent for a sample is vaporized in the pre-column, and a target component is concentrated in the pre-column. The baffle method is a method in which a sample solvent is volatilized on the surface of a baffle liner, and a target component is concentrated on the surface of the liner. Furthermore,
What is called a filler method is a method in which a filler is packed in a liner, the target component is temporarily held in the filler, and after the sample solvent is discharged, the temperature is increased to separate the target component from the filler. It is.

However, each of the above-mentioned conventional sample injection methods has disadvantages.
Not enough. For example, in a system in which glass wool is packed in a liner, a target component may adhere to the glass wool and remain or may be decomposed. Further, in the method in which the reversing cup is provided, the flow rate of the carrier gas may vary. Further, the conventional liner has a drawback that it is impossible to hold a target component in a liquid state in the liner because it is in the form of an elongated linear glass tube, and it is difficult to inject a large amount of the component.

[0004] The conventional mass injection method also has the following disadvantages. For example, in the on-column method, there is a problem that it is difficult to set conditions such as a long pre-column and a solvent exhaust line are required, and an injection speed must be set accurately. In addition, the baffle method has problems that it is not suitable for a low-boiling substance and that a large increase in injection amount cannot be expected. Further, in the packing method, since the target component is heated and desorbed and introduced into the separation column, there is a problem that, in the case of a substance having a high boiling point, it is difficult to separate from the packing material and it is liable to be thermally decomposed.

In addition, it is an object of the present invention to provide a method and an apparatus for injecting a sample without fluctuation of a carrier gas.
Furthermore, the present invention allows for a significant increase in injection volume, and

Next, a procedure for injecting a sample by the injection apparatus will be described. First, a sample is injected from the syringe 6 into the liner 8. Since the shape of the liner 8 is non-linear, the injected sample temporarily stays in the staying chamber 8a of the liner.
Therefore, as in the conventional case where the syringe introduction part 2 and the separation column connection part 11 are on a straight line, the injected sample enters the separation column in a liquid state or is disassembled by touching a metal surface. It does not get lost. For this reason, it is not necessary to pack glass wool in the liner or to provide an inversion cup. Next, the liner 8 is heated by the heater 9 to vaporize the target component, introduced into the separation column 12 from the outlet of the liner, and subjected to component analysis by the detector 13.

In the case of large-volume injection, after injecting a sample into the liner 8, the heater is heated to evaporate only the solvent first, and then discharge from the split purge 15 to concentrate the target component in the liner 8. Next, the split purge valve 16 is closed, and the temperature of the liner 8 is gradually increased by heating with the heater 9, and the target component in the liner is vaporized and introduced into the separation column 12. Therefore, it is not difficult to set conditions as in the conventional large-volume injection method, and it is possible to analyze a high-boiling substance, a low-boiling substance, and a thermally decomposable substance with high accuracy.

After the introduction is completed, the temperature of the liner is further increased, and the high-boiling impurities remaining in the liner are discharged from the split purge 15. This is to prevent the separation column 12 from deteriorating. Note that a large amount of injection can be performed by repeating the injection of the sample into the liner and the discharge of the solvent. For example, if 100 μl injection is repeated 5 times, 500 μl injection can be performed. It is also possible to perform a large amount of injection by controlling the injection speed and injecting while discharging the solvent.
