Sample cell for heat flux differential scanning calorimeter

Abstract

Abstract PURPOSE:To increase the stability of a device in a high-temperature range and to improve the S/N over a wide temperature range by increasing the heat resistance between a heating furnace and sample parts and making the sensitivity of temperature difference detection high, and suppressing heat radiation. CONSTITUTION:Gaps 23 and 24 are provided between sample parts 20 and 21 and a soaking block 1 and they are coupled mutually by several high heat resistance members 25 and 26. Then, thermocouples 9 and 10 are joined to reverse surfaces of the sample parts 20 and 21 to form a temperature detection part. Heat shield covers 30 and 31 are placed over both sample parts 20 and 21 and heat shield covers 32 and 33 are placed covering their reverse sides in contact with the soaking block 1. Further, heater winding is fed with electricity to generate heat and the potential difference between the thermocouples 9 and 10 is measured at the same time to take a high-precision measurement of the temperature difference between samples and a standard material. The heat shield covers 30-33 cover a sample container 4, a standard material container 5, etc., so heat radiation is suppressed; the stability of a base line is improved and the S/N is increased over a wide temperature range.
