PROBLEM TO BE SOLVED: To provide a gas analysis test apparatus capable of adjusting the temperature of the test gas to a predetermined value in a short time, and a reaction device used therefor. SOLUTION: This gas analysis test apparatus comprises a gas feeder for feeding the test gas, the reaction device having a small pipe for adjusting the temperature of the test gas, a temperature adjustment unit for adjusting the temperature of the small pipe, and a reaction chamber for holding a test piece which is brought into contact with the test gas to reform the test gas, a temperature sensor, an analyzer for analyzing the reformed gas, and a recording control device. Because this gas analysis test apparatus employs the small pipe, diffusion of the test gas between the upstream side and the downstream side less easily occurs, and the fluctuation of the composition of the test gas can also be suppressed. In addition, the test gas is heated in a very short time, and the reaction between components constituting the test gas can also be suppressed.
