Peb siv cov ncuav qab zib los txhim kho koj qhov kev paub.Los ntawm kev txuas ntxiv mus saib lub vev xaib no, koj pom zoo rau peb siv cov ncuav qab zib.Cov ntaub ntawv ntxiv.
Cov neeg nyob ib ncig ntawm lub ntiaj teb no siv cov dej haus uas muaj zog los txhim kho lawv txoj kev tsom xam thiab kev tsim khoom.Ib txoj hauv kev zoo tshaj plaws los txheeb xyuas cov dej qab zib no yog capillary electrophoresis.Kab lus no tshuaj xyuas qhov muaj peev xwm thiab qhov cuam tshuam hauv kev sib piv rau lwm txoj hauv kev xws li kua chromatography.
Feem ntau cov dej qab zib muaj zog yog tsim los ntawm cov ntsiab lus muaj caffeine, suav nrog caffeine thiab glutamate.Caffeine yog ib qho stimulant alkaloid pom nyob rau hauv ntau tshaj 63 hom nroj tsuag thoob ntiaj teb.Ntshiab caffeine yog iab, tasteless, dawb khoom.Molecular hnyav ntawm caffeine 194.19 g, melting point 2360 ° C.Caffeine yog hydrophilic nyob rau hauv chav tsev kub nrog qhov siab tshaj plaws concentration ntawm 21.7 g / l vim nws qhov nruab nrab reactivity.
Cov dej qab zib yog cov txheej txheem nyuaj uas muaj ntau yam khoom xyaw, ob qho tib si inorganic thiab organic.Kev txheeb xyuas kev sib cais yog qhov tseem ceeb los xyuas kom raug thiab ntsuas ntau yam ntawm caffeine thiab benzoates.Txoj kev siv feem ntau siv los ntsuas kev sib cais sib cais yog kua chromatography (LC).
Cov kua dej chromatography tau tshaj tawm tias yog siv los ntsuas qhov sib txawv ntawm ntau yam ntawm cov organic molecules, los ntawm cov kab mob me me molecular mus rau cov tshuaj tua kab mob peptides.Qhov sib txawv ntawm qhov sib txawv ntawm qhov txav mus thiab nyob ruaj khov ntawm cov molecules hauv cov qauv hauv qab ntawm kev sib cais ntawm cov kua chromatography.Lub tighter daim ntawv cog lus, qhov zoo dua lub molecule tuav nws txoj hauj lwm.
Lwm txoj hauv kev rau HPLC cov txheej txheem yog kev sib cais los ntawm nqaim bore fused silica capillary electrophoresis, uas siv lub teb hluav taws xob los cais cov tebchaw los ntawm ntau pawg tshuaj hauv ib qho qauv.CE tuaj yeem muab faib ua ntau hom kev sib cais nyob ntawm cov capillaries thiab ions siv.
Txoj kev capillary electrophoresis yog qhov tseem ceeb heev rau kev ntsuam xyuas zaub mov thiab dej haus vim nws qhov zoo ntawm cov qauv qis thiab reagent noj, lub sij hawm luv luv, kev khiav hauj lwm qis, kev daws teeb meem siab, kev tshem tawm siab, yooj yim ntawm kev sim thiab kev loj hlob sai.
Txoj kev sib cais electrophoresis yog raws li qhov sib txawv ntawm cov tshuaj ions nyob rau hauv ib lub cell electrolytic nyob rau hauv qhov kev txiav txim ntawm ib daim ntawv thov hluav taws xob teb.Piv nrog cov khoom siv ua kua chromatography complex, cov khoom siv capillary electrophoresis yog qhov yooj yim.Cov yeeb nkab txuas nrog ib txoj kab nruab nrab ntawm 25-100 m thiab qhov ntev ntawm 20-100 cm txuas ob lub hlwb tsis sib xws, rau hauv uas lub zog hluav taws xob siab (0-30 kV) tau muab los ntawm cov khoom siv hluav taws xob thiab cov hluav taws xob hluav taws xob muaj txiaj ntsig tau ua haujlwm raws li cov khoom siv hluav taws xob. them tus cab kuj.
Feem ntau, lub anode yog suav hais tias yog capillary inlet thiab cathode yog suav tias yog lub qhov hluav taws xob capillary.Ib qho me me ntawm cov qauv yog txhaj hydraulically lossis hluav taws xob rau hauv anode sab ntawm capillary.Motorized infusion yog ua los ntawm kev hloov lub buffer reservoir nrog ib tug qauv vial thiab siv hluav taws xob tam sim no rau ib lub sij hawm kom cia cov khoom txav mus rau hauv capillary.
Hydrostatic infusion xa cov qauv raws li lub siab poob ntawm qhov nkag thiab qhov hluav taws xob ntawm capillary, thiab tus nqi ntawm cov qauv txhaj tshuaj yog txiav txim siab los ntawm kev poob siab thiab lub thickness ntawm polymer matrix.Tom qab cov qauv thauj khoom, ib feem ntawm cov qauv sib sau ua ke ntawm qhov qhib capillary.
Kev sib cais ntawm cov txheej txheem capillary electrophoresis tuaj yeem ntsuas ob txoj hauv kev: kev daws teeb meem sib cais, Rs, thiab kev sib cais ua haujlwm.Qhov kev daws teeb meem ntawm ob tus kws tshuaj ntsuam xyuas qhia tau hais tias lawv muaj peev xwm paub qhov txawv ntawm ib leeg.Qhov loj dua tus nqi Rs, qhov ntau tshaj qhov tshwj xeeb ncov.Kev sib cais kev daws teeb meem ntsuas kev sib cais kev ua tau zoo thiab ntsuas seb qhov kev hloov kho hauv qhov chaw sim tuaj yeem ua rau kev sib cais ntawm cov khoom sib tov.
Kev sib cais kev ua haujlwm N yog ib qho kev xav hauv cheeb tsam uas ob theem nyob rau hauv kev sib npaug nrog ib leeg, sawv cev los ntawm ntau lub vaj huam sib luag sib txawv, nyob ntawm qhov zoo ntawm kem thiab kua.
Ib txoj kev tshawb fawb tshiab luam tawm ntawm Lub Rooj Sib Tham Thoob Ntiaj Teb ntawm Kev Ua Liaj Ua Teb thiab Kev Ua Liaj Ua Teb yog txhawm rau tshawb xyuas lub peev xwm ntawm capillary electrophoresis txhawm rau txheeb xyuas cov nitrogenous compounds thiab ascorbic acid hauv cov dej haus, nrog rau cov txiaj ntsig ntawm electrophoresis variables ntawm cov khoom ntau ntawm txoj kev.
Qhov zoo ntawm capillary electrophoresis tshaj qhov ua tau zoo ntawm cov kua chromatography suav nrog cov nqi tshawb fawb qis thiab kev sib raug zoo ib puag ncig, nrog rau kev ntsuas ntawm asymmetric organic acid lossis cov hauv paus peaks.Capillary electrophoresis muab qhov tseeb txaus rau kev txheeb xyuas cov tshuaj labile hauv cov matrices nyuaj nrog qee qhov tsis yooj yim (dispersion ntawm lub khob noom cookie hauv qhov txav tsis tau, ua kom ntseeg tau qhov sib xws ntawm qhov tsis sib xws, qhov kub thiab txias ntawm cov txheej txheem sib cais).
Hauv cov ntsiab lus, txawm hais tias capillary electrophoresis muaj ntau qhov zoo ntawm kev ua haujlwm siab ua kua chromatography, nws kuj muaj qhov tsis zoo xws li lub sijhawm tshawb xyuas ntev.Kev tshawb fawb ntxiv yuav tsum tau ua los nrhiav txoj hauv kev los txhim kho txoj kev no.
