To provide an analyzer capable of performing measurement with detection sensitivity suitable for specific component concentration contained in a sample.

A flow rate control part 62 controls flow rate of carrier gas supplied from a carrier gas supply mechanism 12 to a cell 44. The flow rate control part 62 reads a detection signal obtained by a detector 48. A peak strength determination part 66 determines whether or not a peak strength of the detection signal exceeds a detection limit strength of the detector 48, and when exceeds the detection limit strength, flow rate control means 70 controls the carrier gas supply mechanism 12 so as to increase the carrier gas flow rate.
