PROBLEM TO BE SOLVED: To provide a gas component analyzer capable of suppressing occurrence of disturbance in a baseline of detection output from a semiconductor gas sensor by suppressing fluctuation of gas flow in a detection channel when supplying sample gas, when circulating carrier gas in a measuring channel provided with a separation means and the semiconductor gas sensor, supplying the sample gas into the measuring channel, and detecting each component by the semiconductor gas sensor, to thereby perform accurate measurement. SOLUTION: This device includes: the measuring channel including the separation means and the semiconductor gas sensor, into which the carrier gas is supplied from the start end side; a supply means for supplying the sample gas into the measuring channel; and a switching means for switching a supply stop state for blocking supply of the sample gas into the measuring channel by the supply means to/from a supply state for permitting supply of the sample gas into the measuring channel by the supply means. The measuring channel is provided with a buffer means for storing a prescribed amount of carrier gas for stabilizing semiconductor gas sensor output. COPYRIGHT: (C)2010,JPO&INPIT
