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.
Kab twg siv rau hauv roj chromatography?
Ob hom kab yog siv rau hauv cov roj chromatography: ntim kab thiab kab capillary. Luv luv, tuab kab ua los ntawm iav los yog stainless hlau raj, packed kab tau siv txij thaum pib ntawm cov roj chromatography.

Hauv kev sib pauv ion chromatography?
Ion chromatography (los yog ion-exchange chromatography) cais ions thiab polar molecules raws li lawv txoj kev sib raug zoo rau cov ion exchanger… thiab cov khoom muaj txiaj ntsig zoo tau thauj khoom kom txaus nyiam rau nws . Txoj cai ntawm kev sib pauv ion yog dab tsi?
Dab tsi yog capillary electrophoresis?
Capillary electrophoresis yog tsev neeg ntawm txoj kev sib cais electrokinetic ua nyob rau hauv submillimeter txoj kab uas hla capillaries thiab hauv micro- thiab nanofluidic channels. capillary electrophoresis siv rau dab tsi? Capillary electrophoresis (CE) yog thawj txoj kev siv rau sib cais thiab kuaj xyuas luv tandem rov (STR) alleles hauv cov chaw soj ntsuam DNA thoob ntiaj tebTshooj no tshuaj xyuas cov ntsiab lus dav dav thiab cov khoom ntawm txhaj tshuaj, sib c
Capillary electrophoresis ua haujlwm li cas?
Capillary electrophoresis yog ib qho kev tshuaj ntsuam xyuas uas cais ions raws li lawv cov electrophoretic txav nrog kev siv hluav taws xob siv hluav taws xob… Cov hom nruab nrab tsis cuam tshuam, tsuas yog ions txav nrog hluav taws xob teb.
Lub raj capillary yog dab tsi?
Capillary Tube - Ib lub raj nrog lub calibrated hauv txoj kab uas hla thiab ntev siv los tswj qhov ntws ntawm cov tub yees Nws kuj tseem txuas lub qhov muag teev rau lub qhov hluav taws xob txuas mus rau qhov ntsuas kub ntawm qhov ntsuas qhov ntsuas qhov ntsuas qhov nthuav dav.
Yuav ua li cas thiaj muab cov ntshav capillary?
Cov ntshav capillary yog tau los ntawm pricking tus ntiv tes rau cov neeg laus thiab pob taws hauv cov menyuam mos thiab menyuam yaus. Cov qauv no tau muab sau nrog lub pipette, muab tso rau ntawm iav swb los yog ib daim ntawv lim, los yog absorbed los ntawm lub ntsis ntawm ib tug microsampling ntaus ntawv .
