Abstract

A thermal analyzer is provided with: a furnace tube; a sample holder; a heating furnace; a measurement chamber; and a measurement unit. The heating furnace comprises a fixing section to be fixed to the furnace tube. The furnace tube is configured to be attachable to and detachable from the heating furnace and provided with an engagement portion that is configured to be engaged with the fixing section at a variable position in the radial direction. A is configured to be detachable from the heating furnace and the furnace tube after inserting the furnace tube into the heating furnace and engaging the engagement portion of the furnace tube with the fixing section while the gap jig is interposed between the heating furnace and the furnace tube to maintain the gap between the heating furnace and the furnace tube in the radial direction to be in the predetermined distance.

Description

technical field [0001] The present invention relates to a thermal analysis device for heating a sample and measuring the physical change of the sample accompanying the temperature change. Background technique [0002] Conventionally, as a method of evaluating the temperature characteristics of a sample, a method called thermal analysis is performed in which a sample is heated and a physical change of the sample accompanied by a temperature change is measured. Thermal analysis is defined as JIS K 0129:2005 "General Principles of Thermal Analysis", and thermal analysis is a method for measuring the physical properties of a sample when the temperature of the measurement object (sample) is controlled by a program. Generally used thermal analysis has the following five methods: (1) differential thermal analysis (DTA) for detecting temperature (temperature difference), (2) differential scanning calorimetry (DSC) for detecting heat flow difference, (3) detecting mass (weight chang...
