Raws li cov dej nkag mus rau daim ntawv, cov xim yuav cais tawm mus rau hauv lawv cov khoom. Capillary kev txiav txim ua rau cov kuab tshuaj mus rau hauv daim ntawv, qhov twg nws ntsib thiab dissolves tus cwj mem . Cov yaj tus cwj mem (the mobile phase) maj mam txav mus rau daim ntawv (theem nyob ruaj ruaj) thiab cais tawm mus rau hauv cov khoom sib txawv.
Ib yam li ntawd, vim li cas Inks cais hauv chromatography?
Ink yog sib xyaw ntawm ob peb dyes thiab yog li peb tuaj yeem ua tau cais cov xim ntawm ib leeg siv chromatography . Thaum twg tus cwj mem raug rau qee cov kuab tshuaj cov xim yaj thiab tuaj yeem cais tawm. Thaum peb nthuav tawm ib daim ntawv nrog tus cwj mem ntawm nws mus rau qhov hnyav, lub tus cwj mem kis thoob plaws daim ntawv thaum lub tus cwj mem yaj.
Ib yam li ntawd, vim li cas txhua tus cwj mem sib cais ua cov xim sib txawv? Nyob rau hauv lub khob kas fes lim, dej hauv lub tus cwj mem nqa lub xim rau ntawm daim ntawv. Thaum lub tus cwj mem dries, cov xim tseem nyob ntawm daim ntawv. Raws li cov dej ntws los txawv pigments ntawm txawv nqi, dub tus cwj mem cais tawm kom pom cov xim uas sib xyaw ua kom nws.
Kuj nug, yog dej ib txwm yog cov kuab tshuaj zoo hauv kev sib cais tus lej?
Ntau haiv neeg cov kuab tshuaj tuaj yeem siv hauv tus cwj mem chromatography. Rau inks uas yog dej soluble, dej yog cov kuab tshuaj ntawm kev xaiv. Rau inks uas tsis soluble nyob rau hauv dej , methanol, ammonium hydroxide, ethanol, acetone, lossis hydrochloric acid tuaj yeem siv los ua cov kuab tshuaj.
Dab tsi ua rau cov xim sib cais hauv ntawv chromatography?
Ib qho hnyav (xws li dej, roj lossis isopropyl cawv) tso cai rau nqus tau ntawv strip. Txawv molecules khiav mus rau ntawv ntawm tus nqi sib txawv. Yog li ntawd, cov khoom ntawm cov tshuaj cais thiab, nyob rau hauv cov ntaub ntawv no, ua pom raws li ib daim hlab ntawm xim ntawm chromatography ntawv.

Koj txhais li cas los ntawm kev sib cais cais tawm?
Txhais kev sib cais ntawm kev yug me nyuam .: qhov tsis muaj peev xwm ntawm ib hom kev yug me nyuam zoo nrog rau cov hom tsiaj vim thaj chaw, kev coj cwj pwm, lub cev nqaij daim tawv, lossis caj ces teeb meem lossis qhov sib txawv
Vim li cas Rutherford tus qauv hu ua tus qauv nuclear?
Rutherford tus qauv ntawm lub atom yog hu ua nuclear atom vim nws yog thawj atomic qauv los feature lub nucleus ntawm nws cov tub ntxhais
Dab tsi yog number case ua los ntawm cov khoom?
Ink yuav ua tau ib tug complex nruab nrab, muaj xws li cov kuab tshuaj, pigments, dyes, resins, lubricants, solubilizers, surfactants, particulate teeb meem, fluorescents, thiab lwm yam ntaub ntawv
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
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
