(54) KOLORIMETRICKÁ PrÚkazNIKOVA TRUBIČKA K ZJlSIOVÁNÍ ALKOHOLU VE VYDECHOVANÉM VZDUCHU(54) COLORIMETRIC IDENTIFICATION TUBE FOR CONTAINING ALCOHOL IN BREATHED AIR
Předmětem vynálezu je kolometrleká průkazníkové trubička ke kvantitativnímu stanovení alkoholu v krvi nepřímou metodou stanovením alkoholu ve vydechovaném vzduchu, založená na reakci alkoholu s chemickým činidlem zachyceným na porézním nosiči. Indikační náplň tvoří dvě vrstvy o výškách 5 mm. Jako nosiče pro jednotlivé indikační vrstvy je používáno silikagelů o různých sorbčních vlastnostech. V závislosti na množství alkoholu v krvi a tím i v dechu, reagují jednotlivé indikační vrstvy v průkazníkové trubičce za vzniku barevných změn.SUMMARY OF THE INVENTION The subject of the invention is a colloidal guide tube for the quantitative determination of blood alcohol by the indirect method of determining alcohol in exhaled air, based on the reaction of the alcohol with a chemical reagent retained on a porous carrier. The indicator filling consists of two layers with a height of 5 mm. Silica gels of various sorption properties are used as carriers for the individual indicator layers. Depending on the amount of alcohol in the blood and thus in the breath, the individual indicator layers in the tube of the reaction produce color changes.
V současné době jsou celosvětově používané průkazníkové trubičky používající jako nosiče silikagel impregnovaný dvojchromanem draselným v koncentrované kyselině sírové. Indikační náplň průkazníkových trubiček je oranžově zbarvena, páry alkoholu redukující dvojchroman nebo chroman draselný v kyselém prostředí, mění oranžové zabarvení náplně v zelené. Průkazníkové trubičky jaou používány Jako kvantitativní, kde při pozitivním testu je hodnocena délka zreagované vrstvy. Podle údajů je nepřesnost uvedených průkazníkových trubiček kolem 50 %. Dále jaou známé dvoustupňové kolometrické průkazníkové trubičky, kde první vrstvu tvoří silikagel lgfpregnovaný dvojchromanem draselným v koncentrované kyselině sírové, druhou vrstvu tvoří silikagel impregnovaný kysličníkem seleničitým v koncentrované kyselině sírové za přidání koncentrované kyseliny áusičné. Přesnost těchto trubiček je vyěáí než 90 %.Currently, the use of carrier tubes using silica gel impregnated with potassium dichromate in concentrated sulfuric acid is used worldwide. The indicator cartridge content is orange colored, alcohol vapors reducing dichromate or potassium chromate in an acidic environment, changing the orange color of the cartridge to green. The test tubes are used as quantitative, where in the positive test the length of the reacted layer is evaluated. According to the data, the inaccuracy of said ID tubes is about 50%. Further, there are known two-stage colometric conduit tubes, wherein the first layer is silica gel coated with potassium dichromate in concentrated sulfuric acid, the second layer is silica gel impregnated with selenium dioxide in concentrated sulfuric acid with the addition of concentrated oleic acid. The accuracy of these tubes is greater than 90%.

Vynález odstraňuje výše uvedené nedostatky koloaetrtekouprůkezníkovou trubičkou k zjišťování alkoholu v krvi, metodou vydechovaného vzduchu, obsahující dvě na aobš uložené vrstvy, jejíž podstatě spočívá v tom, že první vrstva je tvořen· elllkagslea impregnovaným dvojchromenem draselným a kyselinou foefomolybdenovou v koncentrované kyselině sírové ze přídavku koncentrované kyseliny dusičné e druhá vretva je tvořena ailikagelem impregnovaným kyselinou foefomolybdenovou v koncentrované kyselině sírové za přidání koncentrované kyseliny dusičné.The invention removes the above-mentioned drawbacks with a breath-blowing blood alcohol detector tube with an exhaled air method comprising two overlayed layers comprising the first layer consisting of elllkagslea impregnated with potassium dichromate and foefomolybdic acid in concentrated sulfuric acid from a concentrated sulfuric acid addition. nitric acid e the second strand consists of ailica gel impregnated with phephomolybdic acid in concentrated sulfuric acid with the addition of concentrated nitric acid.
Příklad provedeníExemplary embodiment
100 g eilikagelu o zrnitosti 0,8 až 1,0 mm o sorbci kolem 50 jě, chemicky upraveného a aktivovaného při teplotě 500 °C po dobu 48 hodin, po ochlazeni ve skleněné eábrueová baňce za nepřístupu vzdušné vlhkosti se impregnuje roztokem 2 g dvojchromanu draeelného a 1 g kyseliny fosfomolybdenové, rozpuštěných při teplotě 90 až 100 °C ve 100 ml koncentrované kyseliny sírové. Po vychladnutí ee přidá k roztoku 0,25 ml koncentrované kyseliny dusičné. Na impregnaci 100 g eilikagelu ee spotřebuje 50 až 60 ml činidla.100 g of 0.8 to 1.0 mm eilica gel with a sorption of about 50 µl, chemically treated and activated at 500 ° C for 48 hours, after cooling in a glass eábrue flask in the absence of atmospheric moisture, impregnated with a solution of 2 g of draelic dichromate and 1 g of phosphomolybdic acid dissolved at 90 to 100 ° C in 100 ml of concentrated sulfuric acid. After cooling, 0.25 ml of concentrated nitric acid was added to the solution. To impregnate 100 g eilica gel ee consumes 50 to 60 ml of reagent.
Indikační hmota slouží k stanovení alkoholu v krvi od 0,3 promile do 0,8 promile.The indicator mass serves for the determination of blood alcohol from 0.3 per mille to 0.8 per mille.
100 g eilikagelu o zrnitosti 0,8 ež 1,0 mm o sorbci kolem 90 %, chemicky upraveného výše uvedeným způsobem ee impregnuje roztokem 5 g kyseliny foefomolybdenové rozpuštěné při teplotě 110 až 120 °C ve 100 ml koncentrované kyseliny sírové. Po vychladnutí ee přidá k roztoku 1,5 ml koncentrované kyseliny dusičné. Na impregnaci 100 g eilikagelu ee spotřebuje 7o až 80 ml činidle.100 g of eilica gel having a particle size of 0.8 to 1.0 mm and a sorption of about 90%, chemically treated as described above, is impregnated with a solution of 5 g of phephomolybdic acid dissolved at 110 to 120 ° C in 100 ml of concentrated sulfuric acid.
