Cheebtsam ntawm cov roj chromatograph

Jun 05, 2023

Cov muaj pes tsawg leeg ntawm cov roj chromatograph (GC) suav nrog cov qauv ua qauv, kev txhaj tshuaj, kab sib cais roj, lub tshuab ntes, thiab cov ntaub ntawv ua haujlwm.

Cov txheej txheem ua qauv feem ntau suav nrog ob ntu: qauv ua ntej thiab qauv ua ntej, uas tuaj yeem koom nrog cov txheej txheem xws li cov txheej txheem rho tawm, kua-kua extraction, elution, thiab kev txhawb nqa.

Lub tshuab txhaj tshuaj feem ntau muab faib ua ob hom: kev txhaj tshuaj ua kua thiab roj txhaj tshuaj. Kev txhaj tshuaj ua kua yog ua tiav los ntawm kev siv tsis siv neeg lossis phau ntawv samplers, thaum txhaj tshuaj gaseous tsuas yog ua tiav los ntawm phau ntawv thiab tsis siv neeg samplers.

Cov roj theem sib cais kem yog qhov tseem ceeb tshaj plaws ntawm cov roj chromatograph, thiab cov kem sib cais feem ntau muab faib ua ob hom: kab capillary kem thiab kem ntim. Cov kab capillary feem ntau yog sib cais los ntawm cov hlab ntsha capillary, thaum cov kab ntim ntim tau sib cais los ntawm kev sib cuam tshuam ntawm cov khoom siv sab hauv thiab theem roj.

Cov cuab yeej kuaj xyuas feem ntau muaj xws li nplaim hluav taws xob ionization ntes, electron capture detector, thermal conductivity detectors, thiab lwm yam. Nplaim ionization detectors feem ntau siv thiab tuaj yeem ntes tau cov organic feem ntau, tab sis lawv qhov kev tshawb pom muaj tsawg.

Cov txheej txheem ua cov ntaub ntawv suav nrog cov haujlwm xws li kev sau cov ntaub ntawv, kev ua haujlwm, kev tshuaj xyuas, thiab kev tshaj tawm, uas tuaj yeem hloov cov ntaub ntawv tshawb pom mus rau hauv chromatograms rau kev tshuaj xyuas thiab kev txhais lus.
