Abstract

Provided is a sample container and a thermal analyzer. The thermal analyzer allows reliable observation of a film-like sample by solving a problem in that the film-like sample undergoes thermal deformation such as shrinkage or warping when the sample is heated or cooled. Further disclosed is a sample container for a thermal analyzer that is used to measure thermal behaviors of a sample attributable to heating or cooling of the sample and to observe the sample. The container includes a main body having a cylinder-shaped bottom and an open cylinder-shaped top and a transparent or translucent pressure plate that is in contact with an inner surface of the opening of the main body and presses down at least the pressure plate placed on a sample placed on the bottom surface of the main body.

Description

technical field

[0001] The present invention relates to a sample container for performing physical thermal analysis of a sample while heating or cooling, and a thermal analysis device using the sample container. Background technique

[0002] Conventionally, as a method of evaluating the temperature characteristics of a sample, a method called thermal analysis in which a sample is heated or cooled and a physical change of the sample accompanied by a temperature change is measured is performed. Thermal analysis is defined in JIS K0129:2005 "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, ...
