• Main functions of the system: The solid sample is heated by heating the solid sample under ultra-high vacuum to release the resident gas, and         the  released gas is measured online by a high-resolution quadrupole mass spectrometer and its release characteristics are studied
• The main components of the system: It is mainly composed of the main vacuum chamber, the sample preparation chamber, the gas leakage hole     and the gas storage chamber, the vacuum acquisition equipment and the measurement and control system
• The main technical indicators of the system: The main vacuum chamber can achieve a dynamic vacuum degree of 5.0E-7Pa, and the maximum       diameter and thickness of the sample can be tested Φ20mm and the maximum thickness of the sample. The maximum heating temperature on         the  back of the sample is 1100°C (1323K), and the measurement error is ≤5°C; The temperature of the edge of the sample surface can be               measured up to 850°C (1123K). Heating elements can achieve linear heating rates ranging from 0.1 K/min to 100 K/min
