Abstract

Disclosed herein is an evolved gas analyzer and a method for analyzing evolved gas, the apparatus enhancing detection accuracy for gas component without providing the apparatus in a large size. The apparatus includes a heating unit evolving a gas component by heating a sample, a detecting means detecting the gas component, a gas channel connecting the heating unit to the detecting means, the gas channel through which mixed gas of the gas component and carrier gas flows, wherein the gas channel includes a branching channel being open to outside and including a discharge flow rate controlling device, and a flow rate control device controlling the discharge flow rate controlling device based on a detection signal received from the detecting means so as to control the detection signal to be within a predetermined range.
