- Hauv kev sib tw nqaim-ris, qhov kev hloov kho kub no pab kom muaj qhov kub thiab txias sib txawv hauv kab sib txawv hauv kev sib txawv hauv kev sib cais hauv kev sib cais ua ke {2}
- Monolithic txhua yam nthuav tawm cov kev ua kom qis dua rau cov kab mob uas tsis muaj kev ntseeg siab, tshwj xeeb ntawm cov qib siab muaj kev ntseeg siab lossis kev sib cais ua haujlwm {}}
- Cov qhab nia ntau dua cov neeg txhais lus rau lub sijhawm kuaj xyuas luv luv thiab ua kom muaj kev sib zog ntawm Monolithic nqaim-bore-spress rau high-speed sib cais.

Hauv cov roj chromatography
Nyob rau hauv cov roj chromatography (GC), monolithic kem, txawm hais tias muaj ntau yam kev npaj rau ntawm GC cov yam ntxwv zoo, thiab siv cov yam ntxwv ntawm monolithic} Kuv muaj ntau yam zoo, xws li kev sib cais rapperture, uas tuaj yeem txhim kho kev ua tau zoo ntawm GC analyzes .
Kev npaj ntawm monolithic capillary kab ntawv rau GC suav nrog ntau cov qauv tsim nyog, thiab cov qauv kev sib txuas lus tsis tu ncua nyob rau hauv seem |} Tus qauv no tso cai rau kev sib cais ntawm kev tawm tsam raws li lawv kev sib cuam tshuam nrog rau theem nyob ruaj khov thiab lawv diffusion los ntawm cov hws pores {}}
Thaum npaj, monolithic txhua yuav tsum ua kom ua kom muaj kev ua haujlwm GC, thiab kev xaiv cov roj av, thiab cov txheej txheem kev txhaj tshuaj, kom phim cov kev cai tshwj xeeb ntawm cov analytes tau sib cais .
Thawj qhov zoo ntawm cov monolithic capillary kab hauv lawv cov khoom sib cais ntawm kev sib cais thiab ntau dua kev tsom xam cov kev sib cais, cov uas tau rov qab los ntxiv rau kev siv cov kab ntawv ntev dua ntev thiab / lossis cov roj av ntau dua, cov nqi sib cais ntxiv, ntxiv txhim kho kev sib cais sib cais .
Qhov kev txo qis rapperture yog tau txais txiaj ntsig tshwj xeeb hauv cov kev txwv gc tuaj yeem pab kov yeej cov kev txwv GC, ua kom cov cab kuj muaj peev xwm xav tau kev sib cais nrog cov kev xav tau ntau dua nrog cov kev xav tau zoo dua nrog cov kev xav zoo dua nrog cov kev xav tau zoo thiab kev daws teeb meem {2}
Vim lawv cov khoom muaj txiaj ntsig,monolithic chromatogy txhuaHauv GC tau pom cov ntawv thov hauv ntau thaj teb, kev tiv thaiv ib puag ncig, ntsuas hluav taws xob, thiab cov tshuaj petrochemical, thiab kev ntsuas petraphemical, thiab kev ntsuas petrigectical, thiab txhim kho cov txiaj ntsig zoo rau cov txiaj ntsig thiab ntseeg tau cov txiaj ntsig.
