Nyob rau hauv lub neej niaj hnub no, tib neeg yuav tsum tau siv ntau cov khoom iav hauv lawv lub neej txhua hnub, tau ua tiav tsis tuaj yeem tshem cov iav. Cov iav muaj cov khoom ruaj khov, muaj zog tiv taus acid thiab alkali, thiab yog ib qho nyuaj thiab ruaj khov. Nws yog ib qho ntawm cov khoom siv raw rau cov khoom siv tseem ceeb tshaj plaws. Yog xav paub ntxiv txog iav chromatography kab thiab lawv hom thiab qhov sib txawv, nyeem cov kab lus no.
Chromatographic kem yog lub ntsiab lub cev, nyob rau hauv lub gel chromatography tshuab feem ntau siv iav raj los yog organic iav raj. Txoj kab uas hla ntawm chromatography kem loj tsis cuam tshuam qhov degree ntawm kev sib cais, tus qauv tus nqi yog loj, tuaj yeem nce txoj kab uas hla ntawm kem, thiab kev npaj dav dav los ntawm gel kem, loj dua 2 cm inch, tab sis nyob rau hauv cov qauv thaum cov qauv yuav tsum yog. tusyees faib nyob rau hauv lub gel txaj nto. Tsis tas li ntawd, qhov nce hauv txoj kab uas hla, elution kua ntim nce, cov qauv dilution degree.
Iav chromatography kem, nrog qhib loj thiab ceev ceev pub, tsis xav tau kev koom tes ntawm lwm yam twj paj nruag. Lub sab sauv tuaj yeem ua rau lub qhov ncauj txheem txuas nrog lwm cov khoom siv lub qhov ncauj qhov ncauj. Txawm li cas los xij, nws tsis yooj yim los ntsuas, thiab ntau cov kua tau yooj yim tawm hauv qab lub vijtsam.
Ob qhov kawg ntawm cov kab ntawv siab chromatography, feem ntau siv PTFE cov ntaub ntawv, corrosion kuj, acid thiab alkaline kuj tseem tuaj yeem, nyob rau hauv nruab nrab ntawm cov khoom siv iav, cov ntaub ntawv iav organic, yuav tsum tau ua ke nrog lub twj tso kua mis peristaltic, ua kom lub chromatography, lub twj tso kua mis. yuav tsum tau qhab nia, yog tias tsis muaj lub twj tso kua mis siv ntau teeb meem. Cov chav kuaj dav dav tam sim no siv cov kem siab chromatography.
