ZPŮSOB ČIŠTĚNÍ SKLENĚNÝCH TRYSKOVÝCH SEPARATORU MEZI PLYNOVÝM CHROMATOGRAFEM A HMOTOVÝM SPEKTROMETREMMETHOD OF CLEANING GLASS GLAZING SEPARATOR BETWEEN GAS CHROMATOGRAPH AND MASS SPECTROMETER
Vynález se týká způsobu čištění skleněných tryskových separátorů mezi plynovým chromatografem a hmotovým spektrometrem.The invention relates to a method of cleaning glass jet separators between a gas chromatograph and a mass spectrometer.
Hmotový spektrometr vé spojení s plynovým chromatografem se používá zejména při analýze směsí organických látek. Po rozdělení směsi na chromatografické koloně vstupují jednotlivé složky směsi do hmotového spektrometru v pořadí, v jakém se rozdělily na koloně a na základě hmotových spekter lze provést jejich identifikaci.Mass spectrometry in conjunction with a gas chromatograph is mainly used in the analysis of mixtures of organic substances. After separation of the mixture on the chromatographic column, the individual components of the mixture enter the mass spectrometer in the order in which they are separated on the column and can be identified by mass spectra.
Protože hmotový spektrometr pracuje za vysokého vakua, kdežto plynovým chromatografem prochází pod tlakem nosný plyn, musí být mezi plynovým chromatografem a hmotovým spektrometrem,zařazen separátor. Průvozem přístroje dochází k zanášení trysky separátorů, čímž separátor přestává plnit svou funkci. K obnově správné funkce separátorů je třeba separátor vyčistit.Since the mass spectrometer operates under high vacuum, while the carrier gas is passed through the gas chromatograph, a separator must be provided between the gas chromatograph and the mass spectrometer. The separator nozzle becomes clogged by passing the device, which causes the separator to cease to function. To restore proper function of the separators, the separator must be cleaned.
Dosavadní způsoby čištění se provádějí buď mechanicky nebo vymýváním různými kombinacemi organických rozpouštědel. Vzhledem k vysoké ceně separátorů a jeho snadnému porušení při mechanickém čištění je tento způsob riskantní a mnozí proto dávají přednost čištění vymýváním. Čištění tímto druhým způsobem je však zdlouhavé a často není dostatečně účinné.The prior art purification processes are carried out either mechanically or by washing with various combinations of organic solvents. Due to the high cost of the separators and their easy failure in mechanical cleaning, this method is risky and many therefore prefer cleaning by washing. However, cleaning with this second method is tedious and often not effective enough.
Nyní bylo objeveno, že shora uvedené nevýhody nemá způsob podle vynálezu, vyznačený tím, Se se separátor promyje nejdříve směsí kyseliny sírové 90 až 100%ní hmotnostně a dvojchromanu draselného, která obsahuje 5 až 7 hmot196837 nostních dílů dvojchromanu draselného va 100 hmotnostních dílech směsi a potom se nechá chromová směs vykapat, separátor se promyje destilovanou vodou a nakonec nethanolem a nebo acetonem a potom se vysuší. Tento způsob je mnohem účinnější a rychlejší než dosavad pro tento účel užívané a popsané způsoby. Použití nalezne způsob podle vynálezu všude tam, kde se pracuje a přístroji shora popsaného typu.It has now been found that the above-mentioned disadvantages have no method according to the invention, characterized in that the separator is first washed with a mixture of 90 to 100% by weight sulfuric acid and potassium dichromate containing 5 to 7 parts by weight of sodium dichromate. then the chromium mixture is allowed to drip, the separator is washed with distilled water and finally with methanol or acetone and then dried. This method is much more efficient and faster than the previously used and described methods. The process according to the invention can be used wherever it is operated and with apparatus of the type described above.
PříkladExample
Po vyjmutí separátoru z přístroje se separátor vyplní takovým množstvím, asi 60 °G teplé, chromové směsi (5 až 7 % hmotnostních dvojchromanu draselného v kyselině sírové), aby byly trysky zcela ponořeny. Potom se smočí celý vnitřní povrch separátoru, pomocí vakua se proseje tryskami Separátoru několik ml chromové směsi a nechá se 10 až 20 minut působit. Většina chromové směsi.se pak nechá vytéci, její zbytky se odstraní destilovanou vodou za současného použití vakua. Zbytek vody se nechá vytéci, načež se separátor propláchne směsí methanol, aceton 1 : 1. Po vysušení v sušárně lze separátor ihned zapojit do přístroje. Vyčištění je dokonalé a úplné. Takto vyčištěný separátor pracuje bezvadně.After removal of the separator from the apparatus, the separator is filled with an amount of about 60 ° C of warm, chromium mixture (5-7% by weight of potassium dichromate in sulfuric acid) to completely submerge the nozzles. Then the entire inner surface of the separator is wetted, sieved with a few ml of chromium mixture through the nozzles of the Separator and left to act for 10 to 20 minutes. Most of the chromium mixture is then allowed to drain and its residues are removed with distilled water using a vacuum. The remainder of the water was allowed to drain, after which the separator was rinsed with a 1: 1 methanol / acetone mixture. Cleanup is perfect and complete. This cleaned separator works perfectly.
