A METHOD OF MEASURING THE CONCENTRATION OF HYDROGEN AND METHANE IN NITROGEN BY MEANS OF ION MOBILITY SPECTROMETRY |
摘要 |
A method is provided for the quantitative analysis of the contents, in nitrogen, of hydrogen and methane by ionic mobility spectrometry. The method includes the steps of: a) performing a measurement of the apparent hydrogen concentration in the nitrogen to be analyzed; b) performing a measurement of the apparent hydrogen concentration in a flow of the same sample of nitrogen, purified of all impurities but methane; and c) comparing the two measurements. A system of branched lines is also provided for carrying out the method. |
