 EMI1.1 
 



   Die Erfindung betrifft ein Verfahren zur quantitativen Analyse von Gasgemischen mit bekannten Bestandteilen und besteht darin, dass in dem Gasgemisch durch eine rotierende Bewegung in an sich bekannter Weise ein Druckunterschied erzeugt wird, der zur Bestimmung der Menge jedes Bestandteilen des Gasgemisches benutzt wird. Der Druckunterschied infolge rotierender Bewegung kann durch einen   Zentrifugal- oder Schraubenventilator,   eine mit bekannter Geschwindigkeit gegen das Gas bewegte Stauscheibe oder eine ähnliche Vorrichtung erzeugt werden. Verwendet man einen   Zentrifugalventilator,   so nimmt man den Druckunterschied vorteilhaft zwischen zwei Punkten ab, von denen der eine in der Nähe der Achse, der andere in der Nähe des Umfanges liegt, und misst den Druckunterschied in bekannter Weise an einem U-Rohr mit Quecksilber oder dgl.

   Die Quecksilbersäule stellt sich dann entsprechend den Druckunterschieden ein und der Höhenunterschied der Einstellungen in den beiden Schenkeln des U-Rohres ist abhängig von der Zusammensetzung des Gasgemisches bei gegebener Umlaufsgeschwindigkeit. 



   Hat das Gasgemisch beispielsweise zwei verschiedene Bestandteile und bezeichnet man deren 
 EMI1.2 
 
 EMI1.3 
 
 EMI1.4 
 Gasgemisch mit bekannten Bestandteilen den Anteil an jedem einzelnen Gas abzulesen gestattet. 



   Enthält ein Gasgemisch mehr als zwei Bestandteile, so kann man das Verfahren in der Weise ausführen, dass   man zunächst den Druckunterschied   für das Gesamtgemisch bestimmt, dann einen Bestandteil durch ein Absorptionsmittel absorbiert und für den aus zwei Bestandteilen bestehenden Resl ebenfalls den    Druckunterschiedund damitdieZusammensetzung   bestimmt. Der Druckunterschied für die absorbierten Bestandteile kann dann aus den gemessenen anderen Druckunterschieden angegeben werden usw.

 des Gasgemisches benutzt wird.

 EMI1.1
 



   The invention relates to a method for the quantitative analysis of gas mixtures with known constituents and consists in generating a pressure difference in the gas mixture by a rotating movement in a manner known per se, which is used to determine the amount of each constituent of the gas mixture. The pressure difference due to the rotating movement can be generated by a centrifugal or screw fan, a baffle plate moving against the gas at a known speed, or a similar device. If a centrifugal fan is used, the pressure difference is advantageously taken between two points, one of which is near the axis, the other is near the circumference, and the pressure difference is measured in a known manner on a U-tube with mercury or like

   The mercury column then adjusts itself according to the pressure differences and the height difference of the settings in the two legs of the U-tube depends on the composition of the gas mixture at a given circulation speed.



   For example, if the gas mixture has two different components and they are called their
 EMI1.2
 
 EMI1.3
 
 EMI1.4
 Gas mixture with known components allows the proportion of each individual gas to be read off.



   If a gas mixture contains more than two constituents, the method can be carried out in such a way that one first determines the pressure difference for the total mixture, then one constituent is absorbed by an absorbent and the pressure difference and thus the composition of the two-constituent Resl is also determined. The pressure difference for the absorbed components can then be given from the measured other pressure differences, etc.
 EMI1.5
 of the gas mixture is used.

Claims (1)

2. Ausführungsform des Verfahrens nach Anspruch 1, dadurch gekennzeichnet, dass bei Gasgemischen mit mein'als zwei Bestandteilen zunächst ein Druckunterschied in dem gesamten Gas erzeugt wird und dann ein Bestandteil durch Absorption entfernt und in den übrigbleibende Teil wiederum ein Druckunterschied erzeugt wird. 2. Embodiment of the method according to claim 1, characterized in that at Gas mixtures with mein'als two components initially have a pressure difference in the whole Gas is generated and then a constituent is removed by absorption and added to the remaining Part in turn a pressure difference is generated. 3.
