Nyob rau hauv nyias txheej chromatography (TLC), cov theem nyob ruaj khov yog txheej nyias ntawm cov khoom, feem ntau yog silica-based, thiab theem mobile yog cov kua hauv cov sib tov ntawm kev txaus siab yog yaj. Nyias-txheej chromatography los nrog qhov zoo ntawm kev yees duab zoo, ua rau nws cov zis yooj yim rau digitize.
Dab tsi yog theem nyob ruaj khov thiab theem mobile hauv chromatography?
The mobile theem yog hais txog cov kua lossis roj, uas ntws los ntawm cov txheej txheem chromatography, txav cov ntaub ntawv sib cais ntawm tus nqi sib txawv nyob rau theem nyob ruaj khov thaum nyob ruaj khov yog hais txog cov khoom los yog kua theem ntawm chromatography system uas cov ntaub ntawv yuav tsum tau muab cais los yog xaiv…
Yuav ua li cas nyob rau theem nyob ruaj khov hauv chromatography?
theem nyob ruaj khov, hauv kev tshuaj ntsuam chemistry, theem uas lub sijhawm txawb dhau mus hauv txheej txheem ntawm chromatography. … Lub sij hawm txawb ntws los ntawm lub txaj los yog kab ke. Cov qauv uas yuav tsum tau muab cais tawm yog txhaj rau thaum pib ntawm kab thiab raug thauj mus los ntawm qhov system los ntawm theem mobile.
Dab tsi yog theem nyob ruaj khov hauv ntawv chromatography?
Hauv kab chromatography, theem nyob ruaj khov lossis adsorbent yog a khoom thiab theem mobile yog kua. Cov theem feem ntau siv nyob ruaj ruaj yog silica gel thiab alumina. Lub sij hawm mobile los yog eluent yog ib qho ntshiabcov kuab tshuaj los yog sib tov ntawm cov kuab tshuaj.
Lub sijhawm nyob ruaj khov hu ua dab tsi?
Cov sib tov yog yaj hauv cov kua (gas lossis cov kuab tshuaj) hu ua mobile theem, uas nqa nws los ntawm lub kaw lus (ib kem, lub raj capillary, phaj, lossis ib daim ntawv) ntawm cov khoom hu ua lub sijhawm nyob ruaj ruaj.
