PROBLEM TO BE SOLVED: To surely detect an organometallic compound in which a cyclopentadienyl ring is bonded to a metal by a method wherein a gas containing the organometallic compound in which the cyclopentadienyl ring is bonded to the metal is brought into contact with a detecting agent in which sulfuric acid is carried by an inorganic carrier, the metal is separated from the organometallic compound and the precipitation of the metal is detected. SOLUTION: A gas containing an organometallic compound in which a cyclopentadienyl ring is bonded to a metal is brought into contact with a detecting agent in which sulfuric acid is carried by an inorganic carrier. When the organometallic compound in which the cyclopentadienyl ring is bonded to the metal is brought into contact with the sulfuric acid which is carried by the inorganic carrier, the metal is separated from the organometallic compound so as to be precipitated. When the discoloration of the detecting agent during this time is detected, the organometallic compound in the gas can be detected. For example, when a gas which contains a metallocene is brought into contact with a detecting agent in which sulfuric acid is carried by white silical gel, a metal is separated from the metallocene so as to be precipitated, the metal is captured by the detecting agent, and the detecting agent is discolored sharply from a white color to a yellow color or a brown color.
