A method and a system for monitoring combustion condition are provided for monitoring the state of combustion in a garbage incinerator, an internal combustion engine, or the like. Combustion off-gas produced by combustion is collected and ionized to produce ions which are fed to a mass spectrometer for detecting a signal strength associated with an ion for each mass-to-charge ratio. The degree of unsaturation is calculated for an ion detected by the mass spectrometer from the mass-to-charge ratio of the ion. Then, signal strength values associated with ions having the same degree of unsaturation are accumulated for each degree of unsaturation. The monitoring system can keep track of components in combustion off-gas classified into respective compound groups in real time to monitor an exact combustion condition.
