| 摘 要： | 氩的稀释技术早在五十年代开始,到了六十年代,由于采取了超高真空技术和质谱静操态操作,使氩的测试水平大大提高,但到六十年代中期,国内外氩提取系统没有更多的发展,只是近些年来才有价格昂贵的全金属商品氩提取系统。虽然形式不同,繁简不一,但有共同的特点是熔样系统与纯化系统分开。

| Abstract: | A new argon extraction that is different from the general systems for extracting argon from mineral or rock has been set up in our laboratory, Generally, the part for fusing sample is separated form the purefying part in the argon extraction system, but in our new system the getter has been directly put near the crucible of the sample in the quartz bottle. The heating of getter (for example, sponge titanium) is operated by the diffusing heat from the sample oven.Therefore, there are some advantages for the system:1. The electric energy to be only consumed 500 W for fusing sample and heating Ti can be enough utilized.2. The volume of the system is rather small. So it is easier to acquir static ultra-high vaccuin, and to decrease the background of argon.3. The times lasted the experiment is reduced. It is about 70-80 minutes for a sample from fusing sample to the end.4. The results for the standard biotite ZBH-25 in China show that the 1.805?10-9 moleAr/g value by the new system is very close to the 1.813?10-9 mole Ar/g value. The precision is about 0.4%. |
