Capillary kab yog cov roj chromatography (GC) kab uas muaj stationary theem txheejlawv sab hauv es tsis ntim rau hauv kab noj hniav. … Ib kem CG capillary muaj qhov sib cais ntawm tus qauv zoo dua li cov kab ntim khoom, tab sis nws yooj yim dua overloaded los ntawm kev qhia ntau dhau ntawm cov qauv.
Ntev npaum li cas ntawm kab capillary hauv roj chromatography?
Cov kab ntim ntau ntau yog 1.5 - 10m hauv qhov ntev thiab muaj lub taub sab hauv ntawm 2 - 4mm. Capillary kab muaj ib txoj kab uas hla ntawm ob peb feem kaum ntawm ib millimeter. Lawv tuaj yeem yog ib qho ntawm ob hom; phab ntsa-coated qhib tubular (WCOT) lossis txhawb-coated qhib tubular (SCOT).
Kab dab tsi ua hauv roj chromatography?
Kab yog lub plawv ntawm cov roj chromatograph. Nws yog dhau ntawm kev sib cuam tshuam ntawm cov kuab tshuaj (ib tus neeg sib xyaw hauv cov qauv, tseem hu ua analytes) thiab theem nyob ruaj khov nyob rau hauv kem uas sib cais tuaj yeem tshwm sim.
Kem ntev cuam tshuam li cas rau roj chromatography?
Ib kab ntawv ntev dua feem ntau txhim kho kev sib cais. Kev lag luam tawm yog tiaslub sijhawm khaws cia nce qhov sib npaug rau kab ntevthiab qhov tseem ceeb ncov nthuav dav yuav raug pom zoo ib yam vim tias muaj qhov ntev ntev diffusion hauv kab.
