PURPOSE: An isothermal/non-isothermal thermogravimetric analyzer is provided to prevent or minimize the inflow of external air to the inside of a reactor or a loss of inner reaction gas or heat as an external-air breaker of an antenna type is installed on an opening of the reactor.;CONSTITUTION: An isothermal/non-isothermal thermogravimetric analyzer includes a reactor (2), an elevator (4), a detector (5), an external-air breaker (6), a reaction gas introducer (7), a mix chamber (8), and a control member (9). A heater (1) encircles the reactor. The elevator tows a sampler (3) containing a sample by using a wire (40) with a suspension mode and elevates the towed sampler to the inside of the reactor. The detector detects a weight change caused by heating the sample which is elevated to the inside of the reactor. The external-air breaker is mounted between the detector and the reactor and blocks an opening of a sample introduction unit of the reactor. The reaction gas introducer stores various kinds of reaction gases and introduces the stored reaction gases to the inside of the reactor. The mix chamber mixes the various kinds of reaction gases provided by the reaction gas producer according to a test condition. The control member is electrically connected to each device and controls the same.;COPYRIGHT KIPO 2013
