Qhov Tseem Ceeb Qhov txawv - Gas Solid Chromatography vs Gas Liquid Chromatography
Qhov sib txawv tseem ceeb ntawm cov roj chromatography thiab cov pa roj chromatography yog tias nyob rau hauv cov roj chromatography, cov theem nyob ruaj khov yog nyob rau hauv lub xeev ruaj khov whereas hauv cov kua roj chromatography, cov theem nyob ruaj khov yog nyob rau hauv lub xeev ua kua.
Gas chromatography yog cov txheej txheem chromatographic uas theem mobile nyob hauv lub xeev roj. Cov txheej txheem chromatographic yog ib qho kev sim siv los cais, txheeb xyuas thiab qee zaum ntsuas cov khoom hauv qhov sib tov.
Gas Solid Chromatography yog dab tsi?
Gas solid chromatography yog cov txheej txheem chromatographic uas cov theem nyob ruaj khov nyob hauv lub xeev ruaj khov thiab theem mobile yog nyob rau hauv lub xeev gaseous. Cov theem nyob ruaj khov ntawm cov txheej txheem chromatographic yog qhov sib xyaw uas yog siv los cais cov khoom sib xyaw ua ke.
Daim duab 1: Daim duab ntawm Gas Chromatographic Apparatus
Cov roj av chromatography yog siv rau kev sib cais ntawm cov khoom tsis sib xws hauv kev sib tov. Nyob rau hauv cov txheej txheem no, ob qho tib si sib tov thiab theem mobile yog nyob rau hauv lub gaseous xeev. Lub sijhawm txawb thiab qhov sib xyaw kom sib cais yog sib xyaw ua ke. Tom qab ntawd qhov sib tov no dhau los ntawm cov khoom nyob ruaj ruaj. Cov theem nyob ruaj khov yog siv rau sab hauv phab ntsa ntawm lub raj hu ua chromatographic kem. Cov molecules ntawm cov theem nyob ruaj ruaj tuaj yeem cuam tshuam nrog cov molecules hauv theem mobile.
Muaj qhov zoo ntawm kev siv roj chromatography tshaj cov kua roj chromatography. Cov roj av chromatography tuaj yeem siv rau ntawm qhov kub thiab txias vim tias qhov tsis muaj zog thiab ruaj khov siab.
Gas Liquid Chromatography yog dab tsi?
Gas kua chromatography yog cov txheej txheem chromatographic uas cov theem nyob ruaj khov yog nyob rau hauv lub xeev ua kua thiab theem mobile yog nyob rau hauv lub xeev gaseous. Hauv cov txheej txheem no, cov theem nyob ruaj khov yog cov kua dej tsis muaj zog. Qhov chaw nyob ruaj khov no yog siv rau ntawm phab ntsa sab hauv ntawm lub raj hu ua chromatographic kem. Cov phab ntsa sab hauv ua raws li cov khoom txhawb nqa rau theem nyob ruaj khov. Cov theem ntawm lub xov tooj ntawm tes yog cov roj inert xws li Argon, Helium lossis Nitrogen.
Lub sijhawm nyob ruaj khov yog siv rau hauv kem ua ib zaj duab xis nyias ntawm cov kua. Cov yeeb yaj kiab ua kua no muaj txiaj ntsig zoo hauv kev faib cov khoom sib xyaw ua ke ntawm theem nyob ruaj khov thiab theem mobile. Cov txheej txheem no yog qhov zoo dua li cov roj chromatography sib txawv; Piv txwv li, kev sib cais ntawm cov khoom yog siab heev vim muaj ntau yam ntawm cov kua txheej. Txawm li cas los xij, cov kua roj chromatography tsis tuaj yeem siv rau qhov kub thiab txias vim tias cov kua nplaum nyias nyias tsis ruaj khov thiab tuaj yeem ua rau vaporized.

Summary – Gas Solid Chromatography vs Gas Liquid Chromatography
Chromatography yog siv los cais thiab txheeb xyuas cov khoom hauv qhov sib tov. Muaj ob hom roj chromatography, uas yog cov roj chromatography thiab cov kua roj chromatography. Qhov sib txawv tseem ceeb ntawm cov khoom siv roj chromatography thiab cov kua roj chromatography yog tias, hauv cov khoom siv roj chromatography, cov theem nyob ruaj khov yog nyob rau hauv lub xeev ruaj khov whereas, hauv cov kua roj chromatography, cov theem nyob ruaj khov yog nyob rau hauv lub xeev ua kua.
