  Verfahren zur Feststellung des Vorhandenseins von   Atemgiften und Prüfröhrchen   hiezu.

 <Desc/Clms Page number 2> 

 



   Die   Durchführung   der   Prüfung   geht in folgender Weise vor sich :
Durch das Röhrchen 1 wird eine bestimmte Menge der zu prüfenden Luft geleitet. Vom Kieselsäuregel werden die in der Luft enthaltenen Gift-oder Kampfstoffe adsorbiert und daher angereichert. Dann wird eine bestimmte Menge des gelösten farblosen Prüfreagens, also z. B. wässerige Jodsäurelösung, in das   Prüfröhrchen   gegeben. Beim Zusammentreffen des Reagens mit dem Kampfstoff enthaltenden Kieselsäuregel geht eine Reaktion vor sich. Es wird'Jod frei. Dieses reagiert sekundär mit der von vornherein am Kieselsäuregel haftenden Stärke und erzeugt die bekannte Blaufärbung. Diese Färbung bleibt nur auf das Kieselsäuregel   beschränkt   und hebt sieh daher gut von den weissbleibenden Einbettungsschichten ab. 



   PATENT-ANSPRUCHE :
1. Verfahren zur Feststellung des Vorhandenseins von Atemgiften durch Erzeugung einer deutlich sichtbaren   Verfärbung   in mit einem farblosen Adsorptionsmittel wie Kieselsäuregel gefüllten   Prüf-     röhrchen   für Gasspürgeräte, dadurch gekennzeichnet, dass ein farbloses Reagensmittel, insbesondere wässerige   Jod, äurelö.   ung, verwendet wird und dass das Adsorptionsmittel mit einem Stoff, beispiels-

 <Desc / Clms Page number 2>

 



   The test is carried out in the following way:
A certain amount of the air to be tested is passed through the tube 1. The poisonous or warfare agents contained in the air are adsorbed by the silica gel and therefore enriched. Then a certain amount of the dissolved colorless test reagent, so z. B. aqueous iodic acid solution, added to the test tube. When the reagent and the warfare agent-containing silica gel meet, a reaction takes place. It becomes' iodine free. This reacts secondarily with the starch that adheres to the silica gel from the outset and produces the familiar blue color. This coloration is only limited to the silica gel and therefore stands out well from the embedding layers, which remain white.



   PATENT CLAIMS:
1. A method for determining the presence of respiratory toxins by producing a clearly visible discoloration in test tubes for gas detectors filled with a colorless adsorbent such as silica gel, characterized in that a colorless reagent, in particular aqueous iodine, äurelö. ung, is used and that the adsorbent with a substance, for example
