Description
Verfahren zum Nachweis von seßhaften chemischen Kampfstoffen Seßhafte Kampfstoffe treten im Umkreis von Gelbkreuzgran.ateinschl,ägen und nach dem Abregnen auf dem Boden an Steinen, Bäumen, Gebüsch usw. bisweilen in Tröpfchenform auf. Für die Erkennung dieser Kampfstoffe in flüssiger Form, in erster Linie Dichlordiäthylsulfid und ähnlicher Verbindungen der Schwefelreihe sowie der Chlorvinylarsinchloride, werden zur Zeit entweder Reagenspapiere benutzt, die mit Chemikalien imprägniert oder damit in feiner Form bedeckt sind und einen Farbumschlag mit diesen Kampfstoffen geben, oder es werden Pulver oder Pasten verwandt, die in fein verteilter Form Reagenzien enthalten, die solche Farbumschläge zeigen.Method for the detection of sedentary chemical warfare agents Sedentary persons Warfare agents occur in the vicinity of Gelbkreuzgran.ateinschl, ägen and after the rain on the ground on stones, trees, bushes etc. sometimes in droplet form. For the detection of these warfare agents in liquid form, primarily dichlorodiethyl sulfide and similar compounds of the sulfur series and the chlorovinylarsine chlorides, At present, either reagent papers that are impregnated with chemicals are used or are covered with it in fine form and have a color change with these warfare agents give, or powders or pastes are used that contain reagents in finely divided form that show such color changes.
Beide Methoden haben für den Gasspürer Nachteile. Bei Regen und Sturm wehen das Papier und der Staub leicht weg, das Papier wird durch Wasser aufgeweicht und ist in diesem Zustande schlecht verwendbar. Ausgestreuter Staub wiederum wird durch Wasser leicht weggeschwemmt und läßt sich nicht von der Stelle der Reaktion emporheben und auf der Rückseite betrachten.Both methods have disadvantages for the gas detector. In rain and storm the paper and dust blow away easily, the paper is softened by water and is difficult to use in this condition. In turn, scattered dust becomes easily washed away by water and cannot be removed from the site of the reaction lift up and look at the back.
Um diese Übelstände zu beseitigen, wird nach der Erfindung ein das Reagens in feiner Verteilung enthaltender Stift aus einer Trägermasse geeigneter Porosität auf den zu prüfenden Stoff aufgedrückt und die Reaktion .auf dem Stift beobachtet. Die Trägermasse, z. B. Kreide, Gips, Bariumcarbonat, Zinkoxyd, Magnesiumcarbonat, wird mit den betreffenden bekannten Reagenzien imprägniert oder in feinster Pulverform durchsetzt. Man kann mit einem solchen Stift einen viel gräßeren Druck ausüben als mit Papieren oder staubförmigem Reagens. Man kann alsdann den Stift emporheben und den Farbumschlag an ihm selbst erkennen. Hat man ihn benutzt, so kann man ihn durch Anspitzen oder Abschleifen sofort wieder für eine neue Prüfung verwendungsfähig machen.In order to eliminate these inconveniences, the invention is a A stick containing a finely divided reagent from a carrier material is more suitable Porosity imprinted on the substance to be tested and the reaction on the pen observed. The carrier mass, e.g. B. chalk, plaster of paris, barium carbonate, zinc oxide, magnesium carbonate, is impregnated with the relevant known reagents or in the finest powder form interspersed. You can exert much more pressure than you can with such a pen with papers or powdered reagent. One can then lift up the pen and recognize the color change in yourself. Once you have used it, you can get through it Sharpening or grinding can be used again immediately for a new test do.
Es sind bereits Abstreichstifte bekannt, die Indikatoren enthalten und deren Abstrich auf einer mit dem zu prüfenden Stoff getränkten Unterlage den Pi-r-Wert, also saure oderalkalische Reaktion, durch Farbumschlag zu erkennen gestattet. Die mit dem zu @erkennenden Stoff in Berührung gebrachte Masse sitzt dann auf der Unterlage, während der übrige Stift nichts von dem Stoff aufgenommen hat. Bei dem Verfahren nach der Erfindung ist eine geeignete Unterlage nicht erforderlich, da der poröse Stift den .zu. prüfenden Stoff aufnimmt und auf dem Stift die Reaktion beobachtet wird. Der poröse Stift gestattet außerdem den Transport des Giftstoffes in das Laboratorium zwecks genauer Analyse desselben.Scraper pens containing indicators are already known and their smear on a surface soaked with the substance to be tested Pi-r value, i.e. acidic or alkaline reaction, can be recognized by color change. The mass brought into contact with the substance to be @recognized then sits on the While the rest of the pencil has not picked up any of the fabric. In which Method according to the invention, a suitable base is not required because the porous pen the .zu. the substance to be tested and the reaction on the pen is observed. The porous pin also allows the toxin to be transported to the laboratory for a detailed analysis.
