Ion chromatography (los yog ion-exchange chromatography) cais ions thiab polar molecules raws li lawv txoj kev sib raug zoo rau cov ion exchanger… thiab cov khoom muaj txiaj ntsig zoo tau thauj khoom kom txaus nyiam rau nws.
Txoj cai ntawm kev sib pauv ion yog dab tsi?
Ion pauv yog txheej txheem los ntawm cov ions hauv kev daws teeb meem hloov mus rau hauv cov khoom uas tso tawm ions ntawm ntau hom tab sis ntawm tib polarity. Qhov no txhais tau hais tias cov ions hauv cov kev daws teeb meem yog hloov los ntawm cov ions sib txawv thaum xub thawj nyob hauv cov khoom.
Cov tebchaw twg yog cais ion txauv chromatography?
Ion pauv chromatography yog dav siv rau kev sib cais sib txawv xws li carbohydrate thiab cawv isomers nrog rau qab zib phosphates thiab nucleotidesIb theem nyob ruaj ruaj rau ion pauv chromatography yog crosslinked styrene los yog divinylbenzene polymer hloov nrog ntau pawg ua haujlwm.
Ion pauv chromatography ntsuas dab tsi?
Ion chromatography yog siv rau kev ntsuas dej chemistry. Ion chromatographs muaj peev xwm ntsuas concentrations ntawm loj anions, xws li fluoride, chloride, nitrate, nitrite, thiab sulfate, nrog rau cov cations loj xws li lithium, sodium, ammonium, potassium, calcium., thiab magnesium nyob rau hauv qhov chaw-ib-billion (ppb) ntau.
Ion pauv chromatography puas yog kab chromatography?
Ion pauv chromatography feem ntau yog ua nyob rau hauv daim ntawv ntawm kem chromatography. Txawm li cas los xij, kuj tseem muaj cov txheej txheem chromatographic nyias nyias uas ua haujlwm raws li lub hauv paus ntsiab lus ntawm kev sib pauv ion.
