Qhov Tseem Ceeb Qhov txawv - Adsorption vs Partition Chromatography
Adsorption chromatography thiab muab faib chromatography yog ntau yam ntawm chromatography. Adsorption chromatography cais cov tebchaw los ntawm adsorption thaum muab faib chromatography cais cov tebchaw los ntawm kev muab faib. Qhov no yog qhov sib txawv tseem ceeb ntawm adsorption chromatography thiab muab faib chromatography.
Chromatography yog cov txheej txheem kuaj mob uas siv rau hauv cov ntsiab lus ntawm kev sib cais ntawm cov khoom sib tov. Nws muaj ob theem uas yog mobile theem thiab nyob ruaj ruaj theem. Cov theem nyob ruaj khov ntawm adsorption chromatography yog nyob rau hauv lub xeev ruaj khov thaum, hauv kev faib chromatography, cov theem nyob ruaj khov yog nyob rau hauv lub xeev ua kua.
Adsorption Chromatography yog dab tsi?
Adsorption chromatography txhais tau tias yog hom chromatography qhov twg cov kua dej molecules ncaj qha mus rau saum npoo ntawm qhov chaw nyob ruaj khov. Hauv cov ntsiab lus yooj yim, adsorption chromatography tuaj yeem piav qhia raws li cov pa roj lossis kua uas yog adsorbed rau saum npoo ntawm cov khoom. Cov theem nyob ruaj ruaj muaj ntau qhov chaw adsorption.
Cov chaw adsorption no sib txawv hauv kev ua siab ntev hais txog cov molecules uas lawv khi hauv lawv cov txheeb ze ntau. Qhov kev ua haujlwm adsorbent yog txiav txim siab los ntawm cov nyhuv net. Adsorption chromatography siv cov theem mobile hauv cov kua lossis roj lub xeev thiab cov theem nyob ruaj khov hauv lub xeev cov khoom. Txhua tus solute muaj qhov sib npaug ntawm qhov adsorption rau saum npoo ntawm cov khoom thiab solubility hauv cov kuab tshuaj. Yog li ntawd, cov kuab tshuaj yuav txav mus rau theem ntawm lub xov tooj ntawm tes, thiab nyob rau ntawm qhov chaw uas lub xeev sib npaug mus txog, cov kuab tshuaj yuav raug adsorbed mus rau theem nyob ruaj khov.
Daim duab 01: Adsorption Chromatography
Qhov sib txawv ntawm kev mus ncig ntawm cov tebchaw tuaj yeem siv los txheeb xyuas qhov sib xyaw tshwj xeeb. Muaj peb hom adsorption chromatographic cov tswv yim uas yog, ntawv chromatography, nyias txheej chromatography thiab kem chromatography.
Partition Chromatography yog dab tsi?
Partition chromatography yog lwm hom chromatography uas ua haujlwm raws li tib txoj cai nrog kev hloov pauv me ntsis. Cov txheej txheem tshwj xeeb no tau qhia los ntawm Archer Martin thiab Richard Laurence Millington Synge nyob rau lub sijhawm xyoo 1940. Zoo ib yam li lwm cov chromatography variances, muab faib chromatography kuj muaj cov theem nyob ruaj khov thiab theem mobile.
Ob lub sijhawm nyob ruaj khov thiab txawb yog kua. Thaum lub sij hawm ua kua-kua sib cais, ib qho kev sib xyaw tshwj xeeb yog sib cais thaum nws mus txog ob theem ua kua tsis zoo uas tam sim no nyob rau hauv cov xwm txheej sib npaug. Ob theem ua kua yog thawj cov kuab tshuaj thiab cov yeeb yaj kiab ntawm cov kuab tshuaj uas muaj nyob rau hauv kab adsorption.
Kev ua haujlwm ntawm Martin thiab Synge ntawm kev faib chromatography tau ua rau kev txhim kho lwm yam ntawm chromatography xws li roj-kua chromatography, roj chromatography thiab ntawv chromatography. Lub invention ntawm daim ntawv chromatography nyob rau hauv lub xyoo tom ntej ua rau txoj kev loj hlob ntawm nyias txheej chromatography uas yog ib tug advanced technology raws li daim ntawv chromatography.
Dab tsi yog qhov zoo sib xws ntawm Adsorption thiab Partition Chromatography?
- Ob qhov adsorption thiab muab faib chromatography yog ntau yam ntawm chromatography
- Ob hom chromatography muaj nuj nqi raws li tib lub hauv paus ntsiab lus ntawm chromatography
- Ob hom yog siv los cais cov sib xyaw ua ke.
- Ob qhov adsorption thiab muab faib chromatography muaj cov theem nyob ruaj khov thiab txawb.
- Adsorption thiab muab faib chromatography muaj peev xwm cais cov tebchaw hauv peb lub xeev; gas, kua thiab khoom.
- Lub sijhawm txawb ntawm ob hom yog nyob rau hauv cov kua dej.

Summary – Adsorption vs Partition Chromatography
Chromatography yog ib qho txheej txheem uas siv los cais cov tebchaw los ntawm kev sib tov. Adsorption thiab muab faib chromatography yog ob hom chromatography. Cov theem nyob ruaj khov ntawm adsorption chromatography yog lub xeev ruaj khov. Cov theem nyob ruaj ruaj muaj ntau qhov chaw adsorption. Hauv kev faib chromatography, theem nyob ruaj khov yog nyob rau hauv lub xeev ua kua. Lub sijhawm txawb ntawm ob hom yog nyob rau hauv cov kua dej. Qhov txawv ntawm adsorption thiab partition chromatography yog kev sib cais ntawm cov molecules tshwm sim raws li qhov muaj peev xwm adsorption hauv adsorption chromatography thaum sib cais tshwm sim raws li kev faib tawm hauv partition chromatography.
