Ib tug sib tov ntawm tsis paub amino acids tuaj yeem yog cais thiab txheeb xyuas los ntawm txoj kev ntawv chromatography . Lub lim ntawv , uas muaj cov zaj duab xis nyias ntawm cov dej daig rau ntawm nws, tsim cov theem nyob ruaj khov. Cov kuab tshuaj yog hu ua mobile theem lossis eluant. Cov kuab tshuaj txav mus rau ib daim lim ntawv los ntawm kev ua haujlwm capillary.
Ib yam li ib tug yuav nug, vim li cas ntawv chromatography siv rau cov amino acids?
Hydrophobic molecules yuav txav nrawm dua vim tias lawv nyiam ntau dua rau hydrophobic hnyav dua li hydrophilic. ntawv . Daim ntawv chromatography yog tshwj xeeb tshaj yog pab tau nyob rau hauv characterizing amino acids . Qhov txawv amino acids txav ntawm qhov sib txawv ntawm tus nqi ntawv vim qhov sib txawv ntawm lawv pawg R.
Tsis tas li ntawd, cov amino acid twg muaj zog tshaj plaws rau daim ntawv? Leucine
Tom qab ntawd, lo lus nug yog, vim li cas cov xim sib cais hauv chromatography?
Kev cais ntawm tsob nroj Pigments Siv Chromatography . Cov kuab tshuaj nqa cov yaj pigments raws li nws txav mus rau daim ntawv. Cov pigments yog nqa nrog ntawm tus nqi sib txawv vim lawv tsis sib npaug. Yog li ntawd, tsawg soluble pigments yuav txav qeeb ntawm daim ntawv ntau dua li soluble pigments.
Polarity cuam tshuam li cas ntawm daim ntawv chromatography?
Polarity muaj qhov loj cuam tshuam ntawm yuav ua li cas attracted ib tug tshuaj rau lwm yam tshuaj. Qhov loj dua qhov sib txawv, ntau dua polar ib molecule. Koj yuav pom tias thaum koj nce qhov polarity ntawm cov kuab tshuaj, tag nrho cov Cheebtsam ntawm qhov sib tov txav nrawm dua thaum koj chromatography kev sim.

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
Yuav ua li cas koj nthuav qhia cov txheeb cais nyob rau hauv ib daim ntawv qhia?
Cov txiaj ntsig piav qhia suav nrog ib lub rooj nrog cov ntaub ntawv txheeb xyuas tsim nyog xws li. qhov nruab nrab, hom, nruab nrab, thiab tus qauv sib txawv. Cov ntaub ntawv piav qhia yuav tsum muaj feem xyuam rau lub hom phiaj ntawm kev kawm; nws yuav tsum tsis txhob suav nrog rau lub hom phiaj ntawm nws. Yog tias koj tsis mus siv hom nyob qhov twg, tsis txhob suav nrog nws
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Yuav ua li cas koj sau txoj kab nqes nqes intercept daim ntawv nyob rau hauv tus qauv daim ntawv?
Standard form yog lwm txoj hauv kev los sau daim ntawv nqes hav-intercept (as opposed to y=mx+b). Nws sau li Ax+By=C. Koj tuaj yeem hloov daim ntawv nqes hav-intercept rau cov qauv zoo li no: Y=-3/2x + 3. Tom ntej no, koj cais qhov y-intercept (qhov no nws yog 2) zoo li no: Ntxiv 3/2x rau txhua sab ntawm kab zauv kom tau qhov no: 3/2x + y = 3
Cov ntaub ntawv dab tsi xav tau rau daim ntawv chromatography?
Daim Ntawv Chromatography ua haujlwm li cas? dej soluble cwj mem los yog cov cim ntawm ntau hom lossis xim. strips ntawm daim ntawv phuam. dej. rubb cawv. ntsia thawv polish remover. straw los yog xaum los yog cwj mem. khob. daim kab xev
