Abstract: An odor detection device includes a filter including a metal-organic framework in which a metal ion and an organic ligand are bonded and an odor sensor detecting a plant-derived odor substance having a straight chain structure which is included in a sample gas passing through the filter. The filter transmits the odor substance included in the sample gas and removes a volatile compound other than the odor substance from the sample gas.

Abstract: A gas flow path includes: a filter configured to selectively transmit a gas; a tubular member which is provided downstream of the filter and in which an opening area at a downstream end is smaller than an opening area at an upstream end; and a negative pressure generating device which is provided in a stage subsequent to the tubular member and which is configured to suck the gas that has passed through the tubular member. This provides a gas flow path and a gas detection system which can concentrate a detection-target gas species in a real-time manner.
