  • Method for measuring the concentration of impurities in helium by ion mobility spectrometry
    Publication number: 20040053420
    Abstract: A method for the quantitative analysis of the concentration of impurities in helium by means of ion mobility spectrometry is described, which consists in using purified argon together with the helium which has to be analyzed for forming the sample, or pure argon as counterflow gas in the separation zone of the instrument, or finally helium-purified argon mixtures both for the sample gas and for the counterflow gas.

  • Method for measuring the concentration of impurities in nitrogen, hydrogen and oxygen by ion mobility spectrometry
    Publication number: 20030209664
    Abstract: A method for the quantitative analysis of the impurities content in nitrogen, hydrogen and oxygen by means of ion mobility spectrometry is described, consisting in using argon, or a mixture containing no impurities and consisting of the gas which has to be analyzed and argon, as a counterflow gas in the separation zone of the ion mobility spectrometer.

  • Method for measuring the concentration of nitrogen in argon by means of ion mobility spectrometry
    Publication number: 20030201388
    Abstract: 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.
