The utility model discloses a multi-component detection instrument for exhaled gas. The multi-component detection instrument comprises an exhaled gas acquisition and pretreatment module, a sample quantitative sampling module, a sensor detection module, a carrier gas pretreatment module and a control module, through the modular design of the instrument, the instrument is convenient to maintain and upgrade; the exhaled gas is directly detected in a drying and filtering manner, so that the pretreatment time is shortened, more trace trace components in the exhaled gas are retained, and the original state of the exhaled gas is basically retained; a methane sensor array, a hydrogen sensor array and a hydrogen sulfide sensor array are arranged in a sensing gas chamber in the sensor detection module; the sensor array in the sensing gas chamber is an infrared sensor, a metal oxide semiconductor sensor or an electrochemical sensor; through multi-component detection of the sensor array, various diseases such as intestin
