有色金属研究总院研制的YGS-1锆错石墨消气剂在室温具有吸收N_2、CO、H_2、H_2O、CH_4、O_2、CO_2等活性气体的能力,能有效提高电子管等真空器件的真空度。经同台测试证明,它对N_2,CO、H_2的吸气性能都超过了国外同类产品的水平。锆石墨消气剂在加热激活时会放出一定量的气体,但也吸收一定量的气体。我们对此特点进行了质谱分析。一、实验方法及装置实验采用静态定容法。整个装置是玻璃系统(如图1),主要由玻璃泡、四极质谱计探头、镓銦阀、B-A规和消气剂样品室等所组成。用GP3.5-E型高频感应加热设备加热消气剂样品。用铂铑-铂热电偶测量温度。消气剂的放气和残气由SJX-1型四极质谱计分析。
YGS-1 Zirconia-graphite-deficient graphite getter developed by the non-ferrous metals research institute has the capability of absorbing reactive gases such as N 2, CO, H 2, H 2 O, CH 4, O 2 and CO 2 at room temperature and can effectively improve the vacuum degree of vacuum devices such as electron tubes. It has been proved by the same bench test that its gettering performance on N 2, CO and H 2 all surpass the level of similar foreign products. Zircon graphite gas getter will release a certain amount of gas when heated and activated, but also absorb a certain amount of gas. We conducted a mass spectrometry analysis of this feature. First, the experimental methods and devices Experimental static constant volume method. The whole device is a glass system (Figure 1), mainly composed of glass bubble, quadrupole mass spectrometer probe, gallium indium valve, B-A gauge and getter sample chamber. GP3.5-E-type high-frequency induction heating equipment heating getter samples. Measure the temperature with a platinum-rhodium-platinum thermocouple. The getter and bleed of the getter is analyzed by the SJX-1 quadrupole mass spectrometer.
