<p>PROBLEM TO BE SOLVED: To provide an element analyzer not affected by the fluctuations in pressure caused by steam generated in a combustion pipe. SOLUTION: Carrier gas is supplied to a TC combustion pipe 5 by connecting a gas flow rate control part 12 controlling high purity air to a constant flow rate to supply the same as the carrier gas, a humidifier 13 giving humidity to the carrier gas and a check valve 11 for preventing the inflow of measuring gas from the TC combustion pipe 5, and a bypass flow channel 18 for allowing the carrier gas to bypass toward the outlet of an IC reactor is provided on the upstream side of the check valve 11. By this constitution, the rise in the internal pressure of the humidifier 11 caused by the generation of steam in the TC combustion pipe 5 is suppressed and the effect on measuring accuracy can be eliminated.</p> |
