Description
Vynález se týká zařízení, které umožňuje identifikaci alkylskupin z látek vycházejících z plynového chromátografu.The invention relates to a device which enables the identification of alkyl groups from substances derived from a gas chromatograph.
U plynové chromatografie je při identifikaci jednotlivých píků zapotřebí dalších metod a zařízení, například chromatografie za odlišných podmínek, plynová chromatografie spojená s hmotovou spektrometrií, izolace látek a jejich identifikace pomocí ultrafialových, infračervených anebo NMR spekter a podobně. Většina těchto metod je přístrojově náročná.In gas chromatography, other methods and devices are needed to identify individual peaks, for example chromatography under different conditions, gas chromatography coupled with mass spectrometry, isolation of substances and their identification by ultraviolet, infrared or NMR spectra and the like. Most of these methods are instrumental.
Pro identifikaci alkylskupin na chromatografu byla vypracována metoda, která je předmětem autorského osvědčení č. 201 116 a podle níž dochází za určitých pracovních podmínek na platinové sílce k odštěpení alkylu od organického jádra za vzniku metanu.Září zení, které je vhodné k provádění této metody, je předmětem tohoto vynálezu. Zařízení, sestávající z tlakové láhve, k níž je připojen čistič plynu, manostat a manometr je podle tohoto vynálezu vytvořeno tak, že k manometru je připojena přes komůrku detektoru chromatografioká kolona, opatřená dávkovacím zařízením a hydrogenační píckou a mezi píckou a detektorem je umístěn absorber a detektor je spojen se zapisovačem.For the identification of alkyl groups on the chromatograph, a method has been developed which is the subject of the author's certificate No. 201 116, according to which under certain working conditions on platinum silicon the alkyl is cleaved from the organic nucleus to form methane. is an object of the present invention. The apparatus consisting of a cylinder connected to a gas purifier, a manostat and a pressure gauge according to the present invention is designed such that a chromatographic column equipped with a metering device and a hydrogenation furnace is connected to the pressure gauge through a detector chamber and an absorber is placed between the furnace and the detector; the detector is connected to the recorder.
Porovnání ohromatogramu bez tohoto zařízení a s ním ukazuje, které z píků náleží látkám, obsahujícím alkylskupinu.A comparison of the ohromatogram without and with this device shows which of the peaks belong to the alkyl-containing substances.

Na připojeném výkreeu je znázorněno zařízení podle vynálezu, využívající plynového chromátografu. K tlakové láhvi J. je připojen čistič 2 plynu, na který navazuje dále manos tat £ a manometr £· Na manometr £ je napojena přes srovnávací komůrku detektoru £ ohromatografická kolona £, opatřená dávkovacím zařízením £, dále hydrogenační pícka £, Mezi hydrogenační píokou £ a detektorem £ je umístěn absorber 8 s aktivním uhlím. Detektor £ je spojen se zapisovačem 11 a průtokoměrem 10.The attached drawing shows a device according to the invention using a gas chromatograph. A gas purifier 2 is connected to the cylinder 1, which is then connected to a manometer 4 and a manometer. and a detector 8 having activated carbon is placed therein. The detector 6 is connected to a recorder 11 and a flow meter 10.
Funkce zařízení je následující! do proudu nosného plynu, v tomto případě vodíku, který se vede z tlakové láhve 2 přes čistič plynu 2, manostat £ a manometr £ do srovnávací komůrky detektoru £, se nadávkuje dávkovacím zařízením £, s výhodou injekční stříkačkou, směs látek, které se na chromatografické koloně 6 rozdělí. Pó rozdělení projdou rozdělené složky hydrogenační píokou £, která je naplněna platinovou sííkou zahřátou na 800 °C, Na této sítce dochází k odštěpení alkylů z aromatického jádra, případně k rozštěpení uhlíkatého řetězce na metan. Kyslík z molekuly přechází na vodu, dusík na amoniak. Mezi hydrogenační píokou £ a detektor £ je zapojen absorbér 8 naplněný katalyzátorem, kte rý propouští pouze metan. Metan se zaznamenává pomocí detektoru £ na zapisovači 11. Kromě popsaného způsobu se provede normální dělení analyzované směsi na plynovém chromátogramu za stejných pracovních podmínek.The function of the device is as follows! into the carrier gas stream, in this case hydrogen, which is fed from the cylinder 2 through the gas purifier 2, the manostat 4 and the manometer 4 to the detector comparator chamber 6, is dosed with a dosing device 6, preferably by syringe. column 6. After separation, the separated constituents pass through a hydrogenation peak 6 which is filled with a platinum network heated to 800 [deg.] C. On this screen, the alkyls are split off from the aromatic nucleus or the carbon chain is split into methane. Oxygen from the molecule goes to water, nitrogen to ammonia. Between the hydrogenation peak 6 and the detector 8 is connected an absorber 8 filled with a catalyst which permits only methane. Methane is recorded using a detector 6 on a recorder 11. In addition to the described method, normal separation of the analyzed mixture is performed on a gas chromatogram under the same operating conditions.
