四极质谱计以其优异的性能,在科学研究,工业生产中已得到广泛应用,特别是作为残余气体分析仪,使用的场合更加普遍。近年来,国内已生产数种规格的仪器,但与国外商品相比仍有一定的差距。如何进一步稳定提高四极质谱计的性能,使其更具有实用价值。是我们研究探讨的目的。1977年我 Quadrupole mass spectrometer with its excellent performance, in scientific research, industrial production has been widely used, especially as a residual gas analyzer, the use of the occasion is more prevalent. In recent years, China has produced several specifications of the instrument, but compared with foreign products is still a certain gap. How to further stabilize the performance of quadrupole mass spectrometer to make it more practical value. It is the purpose of our research and discussion. I was in 1977
