Abstract:
1. A thermal analyzer, comprising: a furnace tube which is made of a transparent material and is formed into a cylindrical shape, the furnace tube having a gas discharge port which is reduced in diameter and is arranged at a tip end portion thereof in an axial direction; a heating furnace which has a cylindrical shape and externally surrounds the furnace tube; sample holding means for holding a sample, the sample holding means being arranged inside the furnace tube; a first support base; a second support base; a furnace tube fixing part for fixing a rear end portion of the furnace tube in the axial direction to the first support base; a heating furnace fixing part for fixing the heating furnace to the second support base; a measurement chamber which is hermetically connected to the rear end portion of the furnace tube; measurement means for measuring a change in physical properties of the sample, the measurement means being arranged inside the measurement chamber; first movement means for moving the first support base and the second support base between a measurement position, at which the rear end portion of the furnace tube is connected to the measurement chamber and the sample holding means is covered with the heating furnace, and a sample setting position, at which the furnace tube and the heating furnace are advanced toward a tip end side with respect to the measurement position and the sample holding means is exposed on a rear end side with respect to the furnace tube and the heating furnace; and second movement means for moving only the second support base to a sample observation position, at which the heating furnace is advanced toward the tip end side with respect to the measurement position under a state in which the rear end portion of the furnace tube is connected to the measurement chamber, and the furnace tube is exposed in a region including the sample holding means, the thermal analyzer being configured to enable observation of the sample from outside the exposed furnace tube at the sample observation position.
