Beschreibung
Zusammenfassung:	The present invention includes: connecting a pressure varying device to a sample gas introduction port and a gas discharge port of a gas analysis apparatus; depressurizing or pressurizing the sample gas introduction port and the gas discharge port by the pressure varying device; introducing calibration gas from a calibration gas introduction port of the gas analysis apparatus in a depressurized or pressurized state; and calculating a pressure correction factor for the gas analysis apparatus with use of a measurement result of the calibration gas by the gas analysis apparatus.
