Cation exchange chromatography yog ib daim ntawv ntawm ion exchange chromatography (IEX), uas yog siv los cais cov molecules raws li lawv cov nqi saum npoo avCation pauv chromatography, tshwj xeeb tshaj yog, siv ib qho Tsis zoo them ion pauv resin nrog affinity rau molecules muaj net zoo nto nqi.
Yuav ua li cas hauv cation exchanger?
Nyob rau hauv ob qho tib si resins, hydrogen ions ua haujlwm pauv ions nrog hlau cations. Nyob rau hauv cov txheej txheem, raws li kev daws ntawm cov hlau hnyav dhau los ntawm cationic kem, hlau ions raug hloov rau cov hydrogen ions ntawm cov resin.
Yuav ua li cas hauv ion pauv chromatography?
Ion chromatography (los yog ion- pauv chromatography) cais ions thiab polar molecules raws li lawv txoj kev sib raug zoo rau ion exchanger Nws ua haujlwm ntawm yuav luag txhua yam kev them nyiaj molecule-xws li cov proteins loj, me nucleotides, thiab amino acids. … Ob hom ion chromatography yog anion-exchange thiab cation-exchange.
Txoj kev pauv cation yog dab tsi?
Cation exchange yog hais txog cov txheej txheem electrochemical uas tus nqi cation zoo tib yam sib pauv sib npaug ntawm cov tshuaj zoo li dej thiab cov khoom zoo li zeolitetxheej txheem no feem ntau siv los ua kom cov dej kom txo tau nws. corrosiveness. Nws yog dav siv hauv kev lag luam hauv qab no: Hlau xov.
Kom pauv cation ua dab tsi?
Ion pauv chromatography cais ions thiab molecules raws li lawv cov nuj nqis tag nrho saum npoo. Cov xov xwm hauv kab sib pauv cation yog qhov tsis zoo, khi zoo rau cov khoom siv molecules, thiab yog li cations yog siv rau elution ntawm cov khoom sib khi.

Hauv kev sib pauv ion chromatography?
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?
Cov roj twg yog siv rau hauv cov pa roj chromatography?
Cov pa roj carbon monoxide yog cov roj inert siv los nqa cov qauv. Helium (He), nitrogen (N 2 ), hydrogen (H 2 ), thiab argon (Ar) feem ntau siv. Helium thiab nitrogen feem ntau yog siv thiab kev siv helium yog qhov xav tau thaum siv cov kab capillary .
Chromatography originate nyob qhov twg?
Chromatography yog thawj zaug tsim nyob rau hauv Russia los ntawm tus kws tshawb fawb Italian yug Mikhail Tsvet hauv xyoo 1900. Nws tau tsim cov txheej txheem, nws tau tsim cov chromatography, hauv thawj xyoo caum ntawm lub xyoo pua 20th, Feem ntau rau kev sib cais ntawm cov nroj tsuag pigments xws li chlorophyll, carotene, thiab xanthophylls .
Vim li cas alumina siv hauv kem chromatography?
Alumina siv ntau zaus hauv kab chromatography dua li nws nyob hauv TLC. Alumina yog qhov rhiab heev rau cov dej uas khi rau nws: qhov siab dua nws cov dej ntsiab lus, qhov tsawg dua qhov chaw nws yuav tsum khi cov organic tebchaw, thiab yog li tsawg "
On-kem capillary gas chromatography?
Capillary kab yog cov roj chromatography (GC) kab uas muaj stationary theem txheejlawv sab hauv es tsis ntim rau hauv kab noj hniav. … Ib kem CG capillary muaj qhov sib cais ntawm tus qauv zoo dua li cov kab ntim khoom, tab sis nws yooj yim dua overloaded los ntawm kev qhia ntau dhau ntawm cov qauv .
