Ntawv chromatography yog ib txoj kev sib cais yaj tshuaj los ntawm ib leeg. Nws ua haujlwm vim qee yam xim xim yaj hauv cov kuab tshuaj siv zoo dua li lwm tus, yog li lawv taug kev mus ntxiv rau daim ntawv. Ib txoj kab xaum yog kos, thiab me ntsis ntawm tus cwj mem lossis cov xim cog rau ntawm nws.
Ib yam li ntawd ib tug yuav nug, yuav ua li cas yog chromatography siv los cais cov sib tov?
Chromatography yog ua tau ib txoj kev sib cais tawm a sib tov ntawm cov tshuaj, uas yog ingas los yog kua daim ntawv, los ntawm kev cia lawv nkag mus maj mam dhau los ntawm lwm yam khoom, uas feem ntau yog ib tug kua los yog khoom. Raws li lub mobilephase txav mus, nws cais tawm mus rau hauv nws cov khoom ntawm qhov chaw nres tsheb.
Kuj Paub, hom khoom twg yog siv los cais cov sib tov? Cov ntsiab lus
- Kev sib xyaw ua ke tuaj yeem sib cais siv ntau hom kev kawm.
- Distillation siv qhov zoo ntawm qhov sib txawv hauv cov ntsiab lus boiling.
- Evaporation tshem tawm cov kua los ntawm kev daws kom tawm hauv cov khoom siv.
- Lim cais cov khib nyiab ntawm qhov sib txawv.
Ib yam li ntawd, vim li cas cov dyes cais hauv chromatography?
Chromatography siv tau rau cais kev sib xyaw ntawm cov xim sib xyaw. Mixtures uas haum forseparation los ntawm chromatography suav nrog inks, dyes thiab colouring agents hauv zaub mov. txawv Cheebtsam ntawm lawv mixture yuav txav mus txawv tus nqi. Qhov no cais lawv cov khoom xyaw tawm.
Vim li cas peb thiaj li sib cais?
Qhov sib txawv ntawm cov khoom yog, qhov yooj yim nws isto cais cov khoom. ex zoo peb cais tealeaves nrog lub sieve. 1. neeg cais sib tov nyob rau hauv thiaj li yuav ger ib yam khoom uas lawv xav tau. 2. lwm yam neeg cais sib tov tshem tawm cov tsis xav tau.
