Description
Prüfröhrchen zum Nachweis von Alkohol mittels auf einem Trägermaterial aufgebrachter Chromatschwefelsäure Zum Nachweis von Alkohol, insbesondere im sogenannten Prüfröhrchen, ist es bekannt, als Oxydationsmittel Chromatschwefelsäure zu verwenden. Diese ist im allgemeinen auf Träger, wie z. B. auf Kieselgel, aufgebracht. Dieses bekannte Verfahren hat den Nachteil, daß die Reaktion nicht immer gleichmäßig durch die Reaktionsschicht verläuft und in dieser Richtung vom Träger abhängig ist.Detection tube for the detection of alcohol by means of a carrier material applied chromate sulfuric acid For the detection of alcohol, especially in the so-called Detection tube, it is known to use chromate sulfuric acid as an oxidizing agent. This is generally on carriers, such as. B. on silica gel applied. This known method has the disadvantage that the reaction is not always uniform the reaction layer runs and is dependent on the support in this direction.
Die Erfindung erstrebt, die Nachteile der bekannten Prüfröhrchen zu vermeiden. Die Erfindung betrifft ein Prüfröhrchen zum Nachweis von Alkohol mittels auf einem Träger aufgebrachter Chromatschwefelsäure. Die Erfindung besteht darin, daß das Reagenz eine dreiwertige Arsenverbindung enthält. Überraschenderweise hat sich gezeigt, daß ein derartiger Zusatz die Nachweisreaktion derart beschleunigt, daß die Reaktion stets in gleicher Weise vor sich geht und auch unabhängig wird von der Art der Träger, auf denen das Reagenzmittel aufgebracht ist. Als günstig hat sich ein Arsengehalt erwiesen, der, bezogen auf den Chromsäuregehalt, etwa 5% beträgt.The invention seeks to address the disadvantages of the known test tubes avoid. The invention relates to a test tube for the detection of alcohol by means of chromate sulfuric acid applied to a carrier. The invention consists in that the reagent contains a trivalent arsenic compound. Surprisingly it has it has been shown that such an addition accelerates the detection reaction to such an extent that that the reaction always proceeds in the same way and also becomes independent on the type of carrier on which the reagent is applied. As cheap has been shown to have an arsenic content that, based on the chromic acid content, is about 5% amounts to.
Eine vorteilhafte Ausführungsform des erfindungsgemäßen Prüfröhrchens besteht darin, daß das Reagenz außerdem noch geringe Mengen Jod enthält. Durch den Jodzusatz wird die Empfindlichkeit des Prüfröhrchens erhöht. Dabei kann der Jodgehalt des Reagenzes, bezogen auf den Chromsäuregehalt, etwa 0,3% betragen.An advantageous embodiment of the test tube according to the invention is that the reagent also contains small amounts of iodine. Through the The addition of iodine increases the sensitivity of the detector tube. The iodine content of the reagent, based on the chromic acid content, be about 0.3%.
Nachfolgend wird ein Ausführungsbeispiel für die Herstellung eines Präparates für erfindungsgemäße Prüfröhrchen gegeben: 500 g reines, trockenes Kieselgel mit einem Schüttgewicht von 400 bis 500 g/1 und einer Körnung zwischen 0,8 und 1,2 mm werden mit 3,5 g feingepulvertem Kaliumbichromat trocken durchmischt. Anschließend werden 100 bis 200 mg Arsentrioxyd sowie 5 bis 20 mg Jod - beide fein gepulvert - ebenfalls trocken zugefügt und homogen durchmischt. Jetzt werden 300 ml Schwefelsäure einer Konzentration zwischen 90 und 98 Gewichtsprozent aufgebracht. Das Präparat wird in. einer Schüttelvorrichtung gleichmäßig imprägniert. Nach der Imprägnierung wird die Charge einer Wärmeaktivierung unterzogen. Das Präparat wird in einem geschlossenen Gefäß auf eine Temperatur von mindestens 100, höchstens 200° C gebracht. Die Wärmehehandlungszeit liegt zwischen einer und 6 Stunden. Das so behandelte Präparat ist gelbgefärbt. Es wird in ü;blich'er Weise in Alcoteströhrchen verfüllt.The following is an exemplary embodiment for the manufacture of a Preparation for test tubes according to the invention given: 500 g of pure, dry silica gel with a bulk density of 400 to 500 g / 1 and a grain size between 0.8 and 1.2 mm are mixed dry with 3.5 g of finely powdered potassium dichromate. Afterward 100 to 200 mg arsenic trioxide and 5 to 20 mg iodine - both finely powdered - also added dry and mixed homogeneously. Now 300 ml of sulfuric acid applied at a concentration between 90 and 98 percent by weight. The preparation is evenly impregnated in a shaker. After impregnation the batch is subjected to heat activation. The preparation is in a closed Bring the vessel to a temperature of at least 100 and at most 200 ° C. The heat treatment time is between one and 6 hours. The preparation treated in this way is yellow in color. It is filled into Alcote tubes in the usual way.
Bei der Prüfung mit alkoholhaltiger Expirationsluft zeigt das gelbe Präparat praktisch ohne Verzögerung den Alkohol durch intensive Grünfärbung an, sofern der Alkoholgehalt über 0,3 0/0 liegt. Die Länge der verfärbten Zone ist proportional dem Alkoholgehalt der ausgeatmeten Luft und damit proportional dem Alkoholgehalt des Blutes.When tested with expiratory air containing alcohol, it shows yellow Preparation practically without delay the alcohol by intensive green color, if the alcohol content is above 0.3%. The length of the discolored zone is proportional the alcohol content of the exhaled air and thus proportional to the alcohol content of the blood.
Das Arsen kann zweckmäßig teilweise in der Forrn von As J3 vorliegen. Es ist anzunehmen, daß sich diese Verbindung bei dem oben geschilderten Verfahren oder bei ähnlichen Verfahren bildet. .Some of the arsenic can expediently be in the form of As J3. It can be assumed that this connection occurs in the process described above or in similar procedures. .
Die erfindungsgemäße Wirkung scheint darauf zurückzuführen zu sein, daß durch den geringen Zusatz der Arsen(III)-verbindung eine geringe Menge des Chromaas zu dreiwertigem Chrom reduziert wird, so daß das Präparat schwach grüngefärbt ist. Durch die Wärmebehandlung verschwindet die Grünfärbung, ohne daß jedoch die Aktivität des Präparats verschwindet. Die wärmeaktivierten Präparate sind stabil und lagerbeständig.The effect according to the invention seems to be due to that due to the small addition of the arsenic (III) compound, a small amount of the chroma is reduced to trivalent chromium, so that the preparation is slightly green in color. The green color disappears as a result of the heat treatment, but without the activity of the preparation disappears. The heat-activated preparations are stable and storable.
