Ob hom ntawm kab siv hauv gas chromatography : ntim kab thiab capillary kab . Luv, tuab kab ua los ntawm iav los yog stainless hlau raj, ntim kab tau siv txij thaum pib ntawm gas chromatography.

Kuj paub, GC kab yog dab tsi?

Capillary kab yog gas chromatography ( GC ) kab uas muaj cov theem nyob ruaj ruaj txheej txheej lawv sab hauv es tsis tau ntim rau hauv kab noj hniav. Capillary GC kab yog siv los soj ntsuam cov qauv rau tus kheej chemical compounds uas lawv muaj.

Tsis tas li, GC kab ua haujlwm li cas? Cov qauv raug ntsuas yog txhaj rau hauv cov cab kuj siv cov syringe thiab tam sim ntawd vaporizes (dhau mus rau hauv daim ntawv roj). Gas uas ua nce tus qauv cais tawm thaum lawv txav raws tus kem (txiv kab ntxwv), uas muaj cov theem nyob ruaj khov (feem ntau, nws yog txheej nyias nyias ntawm sab hauv phab ntsa ntawm lub kem ).

Tom qab ntawd, dab tsi yog qhov txawv ntawm kab capillary thiab packed kem?

Lub ntsiab qhov sib txawv ntawm cov kab ntim khoom thiab capillary kab yog tias, nyob rau hauv ib kem ntim , qhov chaw nres tsheb yog ntim nyob rau hauv lub qhov cub kem hos, nyob rau hauv ib tug kab mob capillary , nyob ruaj ruaj theem coats lub puab nto ntawm kab noj hniav ntawm lub kem.

Gc siv rau dab tsi?

Gas chromatography ( GC ) yog ib hom chromatography siv hauv analytical chemistry rau kev sib cais thiab txheeb xyuas cov tebchaw uas tuaj yeem ua rau vaporized yam tsis muaj decomposition. Hom kev siv ntawm GC suav nrog kev ntsuas qhov purity ntawm ib yam khoom, los yog cais cov khoom sib txawv ntawm cov khoom sib tov.
