Cov hauv paus ntsiab lus yooj yim thiab hom ntawm cov chromategraphic kem
|
Tus txheej txheem tshiab ntawm cov chromatographic kem yog siv cov kev faib sib txawv ntawm cov khoom sib xyaw ntawm cov theem sib xyaw thiab theem txawb kom ua tiav kev sib cais. Theem nyob ruaj khov yog feem ntau qee hom ntxeem tau khoom, xws li Silica theem, thiab lwm yam mobile theem yog cov kua lossis roj uas dhau los ntawm theem nyob ruaj khov. Raws li cov theem sib txawv thiab mobile theem yuav muab faib ua ntau hom, kua chromatography enciography, thiab sab nrauv kab thiab lwm yam. Hauv kev lag luam kev lag luam, feem ntau siv Chromatographic kem hom suav nrog Silica Gel kem, Alumina kem, Macroporous Resin kem thiab lwm yam. Silica gel kem yog dav siv hauv kev siv tshuaj sib cais, roj av ua kom zoo nkauj thiab lwm daim teb vim nws cov tshuaj zoo thiab muaj hluav taws xob zoo. Alumina kem yog ib qho cuab yeej tseem ceeb rau cais polar compounds vim nws qhov kev xaiv tau muaj peev xwm adsorpt. Macroporous Resin cov kab ntawv yog dav siv hauv kev kho kom zoo thiab cov organic sib cais vim yog lawv cov qauv muaj ntau dua thiab muaj ntau tus qauv microporous. |

Tnws daim ntawv thov ntawm cov chromatographic txhua hauv kev lag luam kev lag luam
Kev lag luam tshuaj lom neeg
Hauv kev ua haujlwm ntawm kev lag luam zoo tshuaj, cov tshuaj chromatographic yog dav siv hauv cov tshuaj sththesis, tsw qablrance extraction, cov khoom lag luam sib cais thiab lwm yam. Piv txwv li, hauv cov txheej txheem ntawm cov tshuaj synthesis, cov chromatographic txhua tuaj yeem siv los cais thiab kho cov tshuaj nruab nrab thiab txhim kho cov tshuaj. Hauv kev rho tawm kev rho tawm, cov chromatographic kem tuaj yeem siv los cais thiab huv ntau yam kev sib luag los txhim kho qhov zoo thiab kev ruaj khov ntawm cov txuj lom. Nyob rau hauv cov khoom ntuj sib cais, sib cais chratographic tuaj yeem siv los rho tawm thiab cais cov khoom xyaw lossis cov kabmob tseem ceeb rau kev txhim kho cov tshuaj tshiab.
► Petrochemical kev lag luam
Hauv kev lag luam petrochemical, cov chromatographic txhua yog siv rau kev ua kom zoo thiab sib cais cov roj av. Roj av cov khoom muaj ntau cov tebchaw ntau yam, xws li hydrocarbons, muaj ntxhiab hydrocarbons, cycloalkanes thiab li ntawd. Cov tebchaw no tuaj yeem sib cais thiab ua kom huv los ntawm kev sib cais ntawm cov chromatography txhua, thiab cov khoom zoo thiab cov khoom siv roj av tuaj yeem hloov kho. Piv txwv, hauv cov txheej txheem ntau lawm ntawm cov roj ntau lawm, cov roj chromatogries thiab txhim kho cov roj purity thiab txhim kho cov roj curity thiab kev ua tau zoo ntawm lubricating roj. Nyob rau hauv kev sib cais ntawm petroleum cracking khoom, chromatographic Txhua yuav siv tau cov khoom lag luam zoo rau cov khoom siv tshuaj ntxiv.
Oc Kev Tswj Xyuas Ib Cheeb Tsam thiab Kev Tswj Xyuas
Hauv kev saib xyuas ib puag ncig thiab tswj, chomatographic Txhua yog siv cais thiab soj ntsuam cov kab mob paug thiab txheeb xyuas cov kab mob ib puag ncig. Ib puag ncig cov qauv yuav muaj ntau cov neeg muaj kuab paug orgoic, cov pa phem ua rau muaj kuab lom thiab roj ntsha. Cov kuab paug no tuaj yeem sib cais thiab cov tshuaj lom neeg los ntawm kev sib cais ntawm cov chromatographic txhua, uas muab ib qho tseeb rau kev soj ntsuam kom raug thiab nrhiav kom tau. Piv txwv li, hauv Dej soj ntsuam zoo, chromatographic Txhua tuaj yeem siv tau cais thiab cov ntaub ntawv tseem ceeb rau kev ntsuas dej ua haujlwm zoo thiab kho kom muaj kuab paug. Hauv cov pa paug pa kev soj ntsuam, cov pa roj chromatographic tuaj yeem sib cais thiab kev ntsuas cov khoom siv hluav taws xob ib puag ncig zoo thiab kev tswj cov pa hluav taws xob.
► Lwm cov tshuaj lom
Ntxiv rau cov teb saum toj no, chromatographic txhua kuj tseem siv dav dav hauv lwm daim teb tshuaj. Piv txwv li, hauv kev npaj cov catalysts, cov chromatographic txhua yuav siv tau cais thiab ua kom muaj kev ua haujlwm ua ntej, txhim kho cov haujlwm thiab kev ruaj ntseg ntawm cov catalyst. Hauv cov txheej txheem ntau lawm, cov khoom siv chomatographic tuaj yeem siv cov khoom siv hluavtaws txhawm rau txhim kho kom zoo thiab ua kev ua haujlwm ntawm cov khoom siv hluavtaws. Hauv kev kho dej khib nyiab, chromatographic Txhua yuav siv tau los tshem cov kuab paug xws li cov organic thiab hnyav hlau order thiab hnyav ua kom huv thiab rov qab siv dej qias.
TNws zoo thiab cov kev txwv ntawm cov chromatographic txhua hauv cov ntawv thov tshuaj
