Title: Method and apparatus for analyzing mixtures of gaseous materials by composition modulation
IPC: G01N1/28
Filed: 1956-04-25
Abstract: <PICT:0814317/III/1> Apparatus for determining the percentage content of a component of a gas mixture, e.g. water vapour in a compressed air line, comprises means for passing the gas mixture to an adsorption cell for the component alternately at a high and low pressure, the resulting difference in the component content in the gas mixture being measured by recording the difference in temperatures at a detector cell at each of the two pressures.  As shown (Fig. 1), a gas mixture in pipe 1 is fed through parallel branches 3, 4 in which the pressures are maintained at 25 and 5 pounds per square inch respectively, through a cyclically - operated three-way valve 8 to an adsorber 15 for the component gas, from which the mixture passes to a detector cell 20 containing a material whose temperature rises proportionately to the quantity of the component gas present, the temperature being measured by a bank of thermocouples 22, and recorded at 23.  The ambient temperature of the adsorption cell 15 is maintained constant.  The record so obtained at 23 is compared with curves obtained with known component content. Two adsorption cells and two detector cells may be employed with the thermo couples measuring the temperature difference continually as the pressures alternate.  For a mixture of several gases, e.g. isobutane, n-butane, isopentane and n-pentane, wherein the isobutane is the key component, the mixture is sent through three modulation systems in series which remove the pentane components before the temperature difference at the alternating pressures is measured.
