Ua ink chromatography , koj muab ib qho me me ntawm tus cwj mem ua cais ntawm ib kawg ntawm ib daim kab xev lim ntawv. Qhov kawg ntawm daim ntawv strip yog muab tso rau hauv ib qho hnyav. Cov kuab tshuaj txav mus rau ntawm daim ntawv sawb thiab, thaum nws nce mus, nws dissolves cov tshuaj sib tov thiab rub lawv mus rau hauv daim ntawv.
Ntxiv mus, koj yuav ua li cas cais cov khoom ntawm tus cwj mem dub siv chromatography?
Chromatography yog ib txoj kev siv los cais cov khoom ntawm ib qho kev sib tov. Nyob rau hauv cov ntaub ntawv ntawm xim dub , tso ib dot tus cwj mem txog 3 cm los ntawm qhov kawg ntawm ib tug strip ntawm chromatography ntawv. Qhov chaw thawj. 5 cm ntawm qhov kawg ntawm lub sawb nyob rau hauv ib qho hnyav xws li cawv.
Ib yam li ntawd, hom chromatography feem ntau yog siv los cais cov khoom ntawm inks? Cov kua yuav ua tau cais los ntawm High Performance kua Chromatography (HPLC), thaum lub cov khoom yog gases cais los ntawm Gas Chromatography . Chromatography yog ib txoj hauv kev los tshuaj xyuas cov sib tov sib xyaw (xws li tus cwj mem ) los ntawm kev cais lawv mus rau hauv cov tshuaj uas lawv tau ua.
Ib yam li ntawd, koj ua li cas cais cov khoom ntawm tus number case?
Los ntawm submersion ntawm chromatography ntawv rau hauv dej, ib qho qauv ntawm tus cwj mem tuaj yeem yog cais nyob rau hauv nws cov cyan, magenta, thiab daj cov khoom . Cov dej ua rau cov tus cwj mem molecules rau "mus ncig" nce daim ntawv strip.
Yuav siv chromatography li cas los cais cov dyes?
Separating dissolved solids - chromatography
- Ib txoj kab xaum yog kos, thiab me ntsis ntawm tus cwj mem lossis cov xim cog qoob loo raug muab tso rau ntawm nws. Muaj ib lub thawv ntawm cov kuab tshuaj, xws li dej los yog ethanol.
- Daim ntawv yog qis rau hauv cov kuab tshuaj.
- Raws li cov kuab tshuaj txuas ntxiv mus rau daim ntawv, cov xim sib txawv sib txawv.

Koj siv tus cwj mem hluav taws xob li cas?
Tig lub hwj chim tawm mus rau lub qhov hluav taws xob thiab thawb lub qhov hluav taws xob qhov hluav taws xob ntsuas qhov ntswg rau hauv qhov nqaim (kub) ntawm qhov chaw txais khoom. Lub tester yuav teeb thiab chirp tsis tu ncua yog tias lub hwj chim tseem nyob
Yuav ua li cas cov khoom siv caj ces hauv txhua lub xov tooj tshiab tsim los ntawm kev faib tawm ntawm tes sib piv nrog cov khoom siv caj ces hauv lub xov tooj qub?
Mitosis tshwm sim nyob rau hauv ob lub nuclei uas zoo tib yam rau thawj nucleus. Yog li, ob lub hlwb tshiab tsim tom qab kev faib tawm ntawm tes muaj tib yam khoom siv caj ces. Thaum lub sij hawm mitosis, chromosomes condense los ntawm chromatin. Thaum saib nrog lub microscope, chromosomes pom nyob rau hauv lub nucleus
Qhov sib txawv ntawm Pearl lub cev thiab tus cwj pwm piav qhia yuav ua li cas txhim kho nws ua tus cwj pwm?
Qhov sib txawv ntawm Pearl lub cev thiab tus cwj pwm piav qhia yuav ua li cas txhim kho nws ua tus cwj pwm? Pearl yog outwardly zoo nkauj tab sis coj cwj pwm qus. Qhov no tsim nws vim hais tias xws li ib tug muaj zog kev zoo nkauj lub Puritans pom zoo, tab sis lawv disdain Pearl vim nws tus cwj pwm muaj zog
Yuav ua li cas koj yuav soj ntsuam cov nyhuv ntawm lub teeb siv ntawm tus nqi ntawm photosynthesis?
Cov nyhuv ntawm lub teeb siv ntawm photosynthesis tuaj yeem tshawb xyuas hauv cov nroj tsuag dej. Qhov kev siv lub teeb yog proportional rau qhov kev ncua deb - nws yuav txo qis raws li qhov deb ntawm lub teeb nce - yog li lub teeb siv rau kev tshawb nrhiav tuaj yeem sib txawv los ntawm kev hloov qhov kev ncua deb ntawm lub teeb mus rau cov nroj tsuag
Yuav siv txoj kev twg los cais cov khoom ntawm tus number case?
Chromatography yog ib txoj hauv kev los tshuaj xyuas cov khoom sib tov los ntawm kev sib cais rau hauv cov tshuaj uas lawv tau tsim. Nws tuaj yeem siv los cais cov khoom sib xyaw xws li tus cwj mem, ntshav, roj av, thiab daim di ncauj. Hauv ink chromatography, koj tab tom sib cais cov xim xim uas ua rau cov xim ntawm tus cwj mem
