    摘要: This invention is directed to a system and a process for protecting a gas purification system from damage comprising passing a stream of impure gas through a catalyst bed and measuring the temperature difference before and after the catalyzed bed reaction through a data analyzer to determine the impurity of the gas prior to controlling the feed of impure gas into or out of a reactor for producing a purified gas. In a preferred embodiment, the catalytic beds may be in parallel form, and the plurality of temperature measurements before and after the catalytic beds is considered by a data analyzer for controlling the impure gas for feeding into the purification reactor.

    摘要: A method for carrying out nitrogen analysis by ionization mobility spectroscopy, at concentrations of few parts per billion (ppb) in argon is described. The method involves the addition of hydrogen in concentration of at least 5 ppb and lower than 100 parts per million (ppm) to the argon to be analyzed; the hydrogen addition step is possibly preceded by a purification operation of the argon flow, so as to reduce the total concentration of impurities other than nitrogen under 1 ppb.
