摘要： An exhaust gas analyzer and an exhaust gas analyzing method capable of analyzing the concentration of particulate matter contained in exhaust gas from an internal combustion in real time are provided. The exhaust gas analyzer includes: an exhaust gas passage hole 21 through which the exhaust gas from the internal combustion is introduced; an optical fiber 25 that applies the laser light in a direction perpendicular to a flow of the exhaust gas flowing through the exhaust gas passage hole; a detector 26 that receives the laser light that has passed through the exhaust gas; a photodetector 71 that receives Mie scattered light generated from particulate matter PM contained in the exhaust gas by irradiating the particulate matter with the laser light; and a personal computer 45 as a calculation unit that calculates a concentration of a component in the exhaust gas based on photoreceiving data of a transmitted light intensity obtained from the detector 26, and calculates a concentration of the particulate matter contained in the exhaust gas based on actual measurement data of a scattered light intensity obtained by the photodetector 71.
