Hauv gas chromatography , tus cab kuj gas yog theem mobile. Tus nqi ntws ntawm cov cab kuj tau ua tib zoo tswj kom muab qhov kev sib cais meej tshaj plaws ntawm cov khoom hauv cov qauv. Cov qauv raug ntsuas yog txhaj rau hauv cov cab kuj gas siv lub syringe thiab instantly vaporizes (dub mus rau hauv gas daim ntawv).

Ntxiv rau qhov no, lub hauv paus ntsiab lus ntawm cov kua roj chromatography yog dab tsi?

Gas kua Chromatography Txoj Cai kev ua haujlwm • Gas kua chromatography khiav ntawm txoj cai ntawm muab faib. Nyob rau hauv GLC cov khoom ntawm vaporize cov qauv yog fractionated vim muab faib ntawm ib tug gaseous mobile theem thiab ib tug ua kua nyob ruaj khov theem tuav hauv kab.

Kuj Paub, dab tsi yog gas kua chromatography cais? Rau cais cov compounds hauv gas - kua chromatography , cov qauv kev daws teeb meem uas muaj cov organic sib txuas ntawm kev txaus siab yog txhaj rau hauv cov qauv chaw nres nkoj uas nws yuav ua vaporized. Cov vaporized kuaj ntawd yog txhaj yog ces nqa los ntawm ib tug inert gas , uas feem ntau yog siv los ntawm helium lossis nitrogen.

Kuj nug, kua chromatography ua haujlwm li cas?

Cov qauv nqa los ntawm cov pa txav ntawm Helium lossis Nitrogen. Kev ua haujlwm siab Ua kua Chromatography ( HPLC ) yog ib daim ntawv ntawm kab chromatography uas tso cov qauv sib tov los yog tshuaj ntsuam xyuas hauv cov kuab tshuaj (lub npe hu ua theem mobile) ntawm kev kub siab los ntawm kab nrog chromatographic packing khoom (stationary theem).

Vim li cas helium siv hauv roj chromatography?

Capillary kab Helium yog feem ntau siv tus cab kuj gas vim nws yog inert thiab tsis-flammable, thiab muaj lub cev muaj zog uas tso cai rau siab daws teeb meem, kub programmed gas chromatography.
