V-zoo li lub taub ntawm daim ntawv yog muab tso rau hauv lub chromatography hnyav thiab ua raws li lub wick los kos cov kuab tshuaj rau hauv daim ntawv, cais pigments Raws li lawv cov txheeb ze solubility thiab molecular hnyav. Daim ntawv tso cai nyob rau hauv cov kuab tshuaj kom txog rau thaum lub Uppermost xim band ze rau saum daim ntawv.
Tom qab ntawd, ib tug kuj yuav nug, yuav ua li cas koj cais cov nroj tsuag pigments los ntawm daim ntawv chromatography?
Daim ntawv chromatography yog cov txheej txheem tseem ceeb hauv kev sib cais thiab kev txheeb xyuas qhov sib txawv cog pigments . Nyob rau hauv cov txheej txheem no, qhov sib tov uas muaj cov pigments yuav tsum tau sib cais yog thawj zaug siv raws li ib qho chaw los yog ib txoj kab rau lub ntawv txog 1.5 cm ntawm lub hauv qab ntug ntawm lub ntawv.
Tsis tas li ntawd, qhov kev txiav txim ntawm cais cov nroj tsuag pigments yog dab tsi? Cov xaj , los ntawm sab saum toj, yuav tsum yog carotene (txiv kab ntxwv), xanthophylls (daj), chlorophyll a (daj-ntsuab), chlorophyll b (xiav-ntsuab), thiab anthocyanin (liab). Txheeb xyuas thiab sau npe rau xim bands ntawm qhuav strips.
Ntxiv rau qhov no, vim li cas cov xim sib cais hauv chromatography?
Cov txheej txheem ntawm chromatography cais cov molecules vim cov txawv solubilities ntawm cov molecules nyob rau hauv ib tug xaiv solvent. Cov kuab tshuaj nqa cov yaj pigments raws li nws txav mus rau daim ntawv. Cov pigments nqa at txawv cov nqi vim lawv tsis sib npaug zos soluble.
Yuav ua li cas cais cov xim photosynthetic?
Ob txoj hauv kev zoo tshaj plaws rau kev sib cais cov xim photosynthetic yog:
- Daim ntawv chromatography - siv ntawv (cellulose) ua lub txaj nyob ruaj ruaj.
- Nyias txheej chromatography - siv ib txheej nyias ntawm adsorbent (xws li silica gel) uas khiav nrawm dua thiab muaj kev sib cais zoo dua.

Yuav ua li cas chromatography cais cov sib tov?
Chromatography yog ib txoj hauv kev ntawm kev sib cais tawm ntawm cov tshuaj sib tov, uas muaj nyob rau hauv cov roj los yog kua daim ntawv, los ntawm kev cia lawv nkag mus maj mam dhau los ntawm lwm yam khoom, uas feem ntau yog kua los yog khoom. Raws li lub sij hawm mobile txav mus, nws cais tawm mus rau hauv nws cov khoom ntawm cov theem nyob ruaj khov
Vim li cas cov amino acids cais hauv daim ntawv chromatography?
Ib qho kev sib xyaw ntawm cov amino acids tsis paub yuav raug muab cais thiab txheeb xyuas los ntawm cov ntawv chromatography. Cov ntawv lim, uas muaj cov zaj duab xis nyias ntawm cov dej daig rau ntawm nws, ua rau lub sijhawm nyob ruaj khov. Cov kuab tshuaj yog hu ua mobile theem lossis eluant. Cov kuab tshuaj txav mus rau ib daim ntawv lim los ntawm kev ua capillary
Yuav ua li cas koj cais ib tug sib tov ntawm pigments los ntawm ib tug number case cartridge?
Txhawm rau cais qhov sib xyaw ntawm cov xim uas yog ob lub dyes, daim ntawv chromatography yog siv. Ib feem me me ntawm qhov sib tov yog muab tso rau hauv cov khoom siv absorbent, ib daim ntawv lim, nrog cov kuab tshuaj. Ob lub dyes yuav txav mus rau nyias thiab tus number case yuav sib cais rau hauv nws cov khoom ntshiab
Koj yuav ua li cas cais cov khoom ntawm tus cwj mem siv chromatography?
Txhawm rau ua tus cwj mem chromatography, koj muab ib qho me me ntawm tus cwj mem kom sib cais ntawm ib kawg ntawm ib daim ntawv lim dej. Qhov kawg ntawm daim ntawv strip yog muab tso rau hauv ib qho hnyav. Cov kuab tshuaj txav mus rau ntawm daim ntawv thiab, thaum nws nce mus, nws dissolves cov tshuaj sib tov thiab rub lawv mus rau hauv daim ntawv
Vim li cas chromatography siv los cais cov sib tov?
Daim ntawv chromatography yog ib txoj hauv kev cais cov tshuaj yaj los ntawm ib leeg. Nws ua haujlwm vim tias qee cov xim xim yaj nyob rau hauv cov kuab tshuaj zoo dua li lwm tus, yog li lawv mus ntxiv rau hauv daim ntawv. Ib txoj kab xaum yog kos, thiab me ntsis ntawm tus cwj mem lossis cov xim cog rau ntawm nws
