Hauv gas chromatography , tus cab kuj gas yog theem mobile. Tus nqi ntws ntawm cov cab kuj tau ua tib zoo tswj kom muab qhov kev sib cais meej tshaj plaws ntawm cov khoom hauv cov qauv. Cov qauv raug ntsuas yog txhaj rau hauv cov cab kuj gas siv lub syringe thiab instantly vaporizes (dub mus rau hauv gas daim ntawv).
Ntxiv rau qhov no, lub hauv paus ntsiab lus ntawm cov kua roj chromatography yog dab tsi?
Gas kua Chromatography Txoj Cai kev ua haujlwm • Gas kua chromatography khiav ntawm txoj cai ntawm muab faib. Nyob rau hauv GLC cov khoom ntawm vaporize cov qauv yog fractionated vim muab faib ntawm ib tug gaseous mobile theem thiab ib tug ua kua nyob ruaj khov theem tuav hauv kab.
Kuj Paub, dab tsi yog gas kua chromatography cais? Rau cais cov compounds hauv gas - kua chromatography , cov qauv kev daws teeb meem uas muaj cov organic sib txuas ntawm kev txaus siab yog txhaj rau hauv cov qauv chaw nres nkoj uas nws yuav ua vaporized. Cov vaporized kuaj ntawd yog txhaj yog ces nqa los ntawm ib tug inert gas , uas feem ntau yog siv los ntawm helium lossis nitrogen.
Kuj nug, kua chromatography ua haujlwm li cas?
Cov qauv nqa los ntawm cov pa txav ntawm Helium lossis Nitrogen. Kev ua haujlwm siab Ua kua Chromatography ( HPLC ) yog ib daim ntawv ntawm kab chromatography uas tso cov qauv sib tov los yog tshuaj ntsuam xyuas hauv cov kuab tshuaj (lub npe hu ua theem mobile) ntawm kev kub siab los ntawm kab nrog chromatographic packing khoom (stationary theem).
Vim li cas helium siv hauv roj chromatography?
Capillary kab Helium yog feem ntau siv tus cab kuj gas vim nws yog inert thiab tsis-flammable, thiab muaj lub cev muaj zog uas tso cai rau siab daws teeb meem, kub programmed gas chromatography.

Cov txheej nyias nyias chromatography yog dab tsi thiab nws ua haujlwm li cas?
Nyias-txheej chromatography (TLC) yog ib qho txheej txheem chromatography siv los cais cov khoom sib xyaw uas tsis yog-volatile. Tom qab cov qauv tau siv rau ntawm lub phaj, cov kuab tshuaj los yog cov kuab tshuaj sib tov (lub npe hu ua lub sijhawm txawb) yog kos rau ntawm lub phaj ntawm capillary nkaus
Nyias txheej chromatography txawv ntawm daim ntawv chromatography li cas?
Qhov sib txawv ntawm cov txheej nyias nyias chromatography (TLC) thiab ntawv chromatography (PC) yog tias, thaum lub sij hawm nyob ruaj ruaj hauv PC yog ntawv, cov theem nyob ruaj khov hauv TLC yog txheej nyias ntawm cov khoom siv tsis zoo uas txhawb nqa ntawm lub tiaj tus, tsis muaj zog
Vim li cas cov kua siv lead ua kua hloov xim nrog kub?
Cov molecules hauv cov kua siv lead ua kua tuaj yeem txav mus los ntawm nws tus kheej, xws li hauv cov kua, tab sis nyob twj ywm me ntsis, xws li hauv cov khoom siv lead ua (khoom). Cov kua siv lead ua kua no teb rau kev hloov pauv ntawm qhov kub thiab txias los ntawm kev hloov xim. Raws li qhov kub thiab txias, lawv cov xim hloov ntawm liab mus rau txiv kab ntxwv, daj, ntsuab, xiav, thiab ntshav
Gas kua chromatography siv rau dab tsi?
Gas chromatography (GC) yog ib hom chromatography siv nyob rau hauv analytical chemistry rau kev sib cais thiab txheeb xyuas cov tebchaw uas tuaj yeem vaporized yam tsis muaj decomposition. Kev siv ntawm GC suav nrog kev ntsuas qhov purity ntawm ib yam khoom, lossis cais cov khoom sib txawv ntawm cov khoom sib xyaw
Gas chromatography yog dab tsi thiab nws ua haujlwm li cas?
Hauv cov pa chromatography, cov pa roj carbon monoxide yog theem mobile. Tus nqi ntws ntawm cov cab kuj tau ua tib zoo tswj kom muab qhov kev sib cais meej tshaj plaws ntawm cov khoom hauv cov qauv. Raws li cov qauv sib cais tawm thiab nws cov khoom sib xyaw ua ke taug kev raws kab ntawm qhov sib txawv ntawm qhov sib txawv, tus ntsuas qhov siab thiab sau lawv
