Classification: CPC C  G | IPC C

Claim 1:
2. A sensor for detecting limonene as a target substance in a gas sample, comprising:
a target substance uptake unit including a container that holds an acetylcholinesterase aqueous solution, wherein the target substance uptake unit brings the acetylcholinesterase aqueous solution into contact with the gas sample to dissolve a target substance in the gas sample into the acetylcholinesterase aqueous solution;
a supply unit including a liquid storage unit that holds an acetylcholine aqueous solution,
a reaction unit including a reaction vessel connected to the container of the target substance uptake unit and the liquid storage unit of the supply unit, wherein the reaction unit mixes the solution delivered from the target substance uptake unit and the acetylcholine aqueous solution supplied from the supply unit; and
a detection unit connected to the reaction vessel of the reaction unit, wherein the detection unit measures a change in an amount of acetylcholine decomposition product produced in the solution delivered from the reaction vessel of the reaction unit.
