Hauv kab chromatography tus qauv yog siv rau sab saum toj ntawm lub kem thiab cov kua mobile theem tso cai rau ntws los ntawm lub kem cuam tshuam kev sib cais ntawm cov qauv siv. TLC muaj txiaj ntsig rau kev txheeb xyuas los ntawm kev sib cais. Kem chromatography yog pab tau rau kev npaj sib cais.

Ua kom pom qhov no, kab chromatography cuam tshuam li cas rau TLC?

Kem chromatography yog lwm hom kua chromatography . Nws ua haujlwm zoo li TLC . Tib theem nyob ruaj ruaj thiab tib theem mobile siv tau. Es tsis txhob kis ib txheej nyias ntawm cov theem nyob ruaj ruaj rau ntawm lub phaj, cov khoom tau ntim rau hauv ib lub iav ntev, kem xws li hmoov los yog slurry.

Tsis tas li ntawd, hom chromatography yog kem chromatography? Kem chromatography hauv chemistry yog ib chromatography txoj kev siv los cais ib qho tshuaj lom neeg los ntawm kev sib tov.

Yog li ntawd, TLC thiab PC cuam tshuam li cas rau ib leeg?

Cov yooj yim sib txawv ntawm nyias txheej chromatography ( TLC ) thiab ntawv chromatography ( PC ) yog li ntawd, thaum tus nyob ruaj khov theem hauv PC yog ntawv, tus nyob ruaj khov theem hauv TLC yog ib txheej nyias ntawm cov khoom siv inert txhawb rau ntawm lub tiaj tus, tsis muaj zog.

Dab tsi cuam tshuam rau Rf qhov tseem ceeb hauv TLC?

Rf tus nqi thiab reproducibility tuaj yeem ua tau cuam tshuam los ntawm ntau qhov sib txawv yam xws li txheej thickness, noo noo ntawm lub TLC phaj, hlab ntsha saturation, kub, qhov tob ntawm mobile theem, xwm ntawm lub TLC phaj, qauv loj, thiab hnyav parameters. Cov teebmeem no ib txwm ua rau nce Rf tus nqi.
