1. A gas chromatography analysis system comprising:
a gas chromatograph main body comprising an upper surface on which a plurality of injection ports including a first injection port and a second injection port are provided, wherein a first pin and a second pin are provided on the upper surface of the gas chromatograph main body, and positional relationship between the first injection port and the second injection port is the same as positional relationship between the first pin and the second pin;
an injector having a syringe for injecting a sample though each of the injection port and arranged on the gas chromatograph main body; and
a sampler for supplying a vial containing liquid to the injector, wherein the sampler has a hole that is configured for being engaged with the first pin in a first state and the second pin in a second state,
in the first state where the first pin and the hole are engaged with each other, the sampler has a specific positional relationship with the injector arranged on the upper surface of the gas chromatograph main body to arrange the syringe directly above the first injection port, and
in the second state where the second pin and the hole are engaged with each other, the sampler has the same specific positional relationship with the injector arranged on the upper surface of the gas chromatograph main body to arrange the syringe directly above the second injection port.
