1. A gas chromatography analysis method comprising:
separating components included in a sample gas by introducing the sample gas into a separation column using carrier gas; and
detecting the components in the sample gas that has passed through the separation column and has been introduced into a detector, wherein
the detecting includes
generating hydrogen gas and oxygen gas by electrolysis of water in a gas generator,
taking out generated hydrogen gas from a hydrogen gas outlet of the gas generator individually and generated oxygen gas from an oxygen gas outlet of the gas generator individually, and
supplying the taken-out hydrogen gas through a first flow path to the detector, without any chromatography columns therebetween, as detector gas and oxygen gas through a second flow path directly to the detector, without any chromatography columns therebetween, as detector gas with each flow rate of the taken-out hydrogen gas and oxygen gas being independently controlled.
