SAMPLE CELL FOR THERMAL ANALYSIS

PROBLEM TO BE SOLVED: To obtain a sample cell by which heat can be measured precisely by a method wherein, in a thermal analysis, the sample cell is provided with a lid composed of a material whose light transmittance is high and with a container composed of a material whose thermal conductivity is high. SOLUTION: A material for a lid 1 is not limited to quartz, and a transparent material which can transmit light at a required wavelength sufficiently according to the optical characteristic of a sample 3 can be selected. The lid 1 is placed in a lid receiver part 4, the upper-part sidewall of a container 2 is bent to the inside, and the lid 1 can be fixed to the container 2. Thereby, it is possible to prevent the composition of the sample 3 from being changed when the low- boiling-point component of the sample 3 is heated and evaluated during a measurement. As a material for the container 2, aluminum, platinum, copper, gold, silver or the like whose reactivity with the sample 3 is small and whose heat conductivity is good is suitable. A result of high accuracy is obtained with the sample 3, to be measured, whose volatility is high. Thereby, when the thermal characteristic in the light-heat complex reaction of the sample 3 with volatility is measured, it is possible to prevent the vaporization of the sample and a change in its composition, and a quantity of heat can be measured precisely.
