Abstract
This invention makes it possible to measure a concentration of a gas component having the adsorption even thought the concentration is low, and to improve a response speed of the measurement of the concentration, and comprises a body that has an introduction port to introduce a sample gas into a measurement cell, a laser light irradiation part that irradiates the laser light on the measurement cell, a heating pipe that applies heat to the sample gas introduced into the introduction port, a flow rate limit part that makes the sample gas at a negative pressure and that introduces the negative-pressurized heated sample gas into the body, and a negative pressure pump that keeps inside of the measurement cell and a flow channel from a downstream side of the flow rate limit part to the measurement cell at the negative pressure.
