Cov txheej txheem chromatography raws li kev faib tawm tau zoo heev ntawm kev sib cais, thiab txheeb xyuas cov molecules me me li amino acids, carbohydrates, thiab fatty acids. Txawm li cas los xij, affinity chromatographies (ie. ion-exchange chromatography) muaj txiaj ntsig zoo dua hauv kev sib cais ntawm macromolecules li nucleic acids, thiab proteins.
Rau qhov kev sib cais yog siv chromatography?
Chromatography yog txheej txheem rau sib cais cov khoom sib xyaw. Txhawm rau kom tau txais cov txheej txheem pib, qhov sib tov yog yaj hauv ib yam khoom hu ua lub sijhawm txawb, uas nqa nws los ntawm cov khoom thib ob hu ua theem nyob ruaj khov.
Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm kev siv chromatography ua cov txheej txheem sib cais?
Qhov Zoo ntawm Chromatography
Precise kev sib cais, tshuaj xyuas, thiab kev ua kom huv yog ua tau siv chromatography. Nws xav tau cov qauv qis heev. Nws ua haujlwm ntawm ntau yam qauv xws li tshuaj, khoom noj khoom haus, plastics, tshuaj tua kab, huab cua thiab dej kuaj, thiab cov ntaub so ntswg rho tawm.
Chromatography siv qhov twg?
Chromatography kuj yog siv los pab ntes cov neeg phem. Raws li cov kev pab cuam xws li CSI, roj chromatography yog siv los soj ntsuam cov ntshav thiab cov qauv ntaub, pab txheeb xyuas cov neeg ua txhaum cai thiab coj lawv mus rau kev ncaj ncees. Nws yog qhov tseeb pom tias chromatography yog ib tus neeg tsis paub zoo thaum nws los ua kom koj noj qab nyob zoo thiab nyab xeeb txhua hnub.
Qhov twg ntawm chromatography yog siv loscais cov qauv?
Ua kua chromatography yog cov txheej txheem siv los cais cov qauv rau hauv nws tus kheej. Qhov kev sib cais no tshwm sim raws li kev sib cuam tshuam ntawm tus qauv nrog rau theem mobile thiab nyob ruaj khov.
