Qhov zoo ntawm kev sib cais thiab cov ntaub ntawv txheeb xyuas tuaj yeem cuam tshuam los ntawm tailing Yog li ntawd, yog tias tailing muaj nuj nqis, nws muaj peev xwm tso qhov kev txwv ntawm tus nqi siab tuaj yeem sib tw.. Muaj ob txoj hauv kev los txiav txim siab qhov siab tshaj plaws: Tailing factor (T f) - dav siv hauv kev lag luam tshuaj.
Dab tsi yog qhov tseem ceeb ntawm tailing factor hauv HPLC?
Tag nrho cov lus teb (2) Symmetrical peaks nrog tailing yam ntawm 1 (qhov no yog qhov zoo tshaj plaws tailing yam ntawm cov hoob kawm) ua rau muaj tseeb intergration ntawm lub ncov cheeb tsam thiab kuj ncov hight specailly nyob rau hauv quantitative tsom xam.
tailing factor yog dab tsi?
Symmetry factor (S, tseem hu ua "tailing factor") yog tus coefficient uas qhia txog qib ntawm qhov siab tshaj plaws symmetry… Ceev faj yuav tsum tau vim ob qho tib si theoretical phaj tooj thiab symmetry yam yuav hloov nyob ntawm seb hom kev tsom xam thiab analytical tej yam kev mob siv.
Lub ntsiab lus ntawm tailing hauv chromatography yog dab tsi?
Chromatographic ncov hauv (a) yog ib qho piv txwv ntawm tailing, uas tshwm sim thaum qee qhov chaw ntawm qhov chaw nyob ruaj khov khaws cov kua dej ntau dua li lwm qhov chawLub ncov hauv (b) yog ib qho piv txwv ntawm fronting, uas feem ntau yog tshwm sim ntawm overloading kab nrog qauv.
Vim li cas nws tseem ceeb rau GC peaks kom sib npaug?
Qhov zoo tshaj plaws, lub ncov hauv chromatogram tso saib cov duab sib luag (Gaussian nkhaus). Yog tias cov qauv txhaj tshuaj ntau dhau, qhov peaks qhia qhov tseem ceeb tailing, uas ua rau muaj kev sib cais tsis zoo. Feem ntau cov detectors yog cov rhiab heev thiab tsis xav tau ntau cov ntaub ntawv thiaj li tsim tau ib tug detectable teeb liab.

Vim li cas kev ceeb toom kev tso cai tseem ceeb hauv kev tshawb fawb?
Qhia kev pom zoo yog ib feem tseem ceeb ntawm rau npe rau hauv kev sim tshuaj vim nws muab cov ntaub ntawv muaj peev xwm rau cov neeg koom nrog txhua yam lawv xav tau kom nkag siab txog yam lawv tuaj yeem pab dawb Tsis muaj kev pom zoo rau cov ncauj lus tej zaum yuav tsis nkag siab qhov lawv koom nrog .
Vim li cas cov ntaub ntawv tseem ceeb tseem ceeb rau kev tswj hwm tebchaws Askiv?
Cov ntaub ntawv raug cai ntawm cov thawj coj hauv tebchaws Askiv ua haujlwm qhov tseem ceeb ntawm keeb kwm ntawm no lub sijhawm. Cov thawj coj hauv tebchaws Askiv ntseeg tias txhua qhov kev qhia, kev npaj, txoj cai, kev txiav txim siab, kev pom zoo, kev tshawb nrhiav yuav tsum tau sau kom meej.
Vim li cas cov cim tseem ceeb tseem ceeb?
Background. Cov cim tseem ceeb yog qhov tseem ceeb cov ntsiab lus ntawm kev saib xyuas tus neeg laus lossis tus menyuam qhov kev vam meej thaum mus pw hauv tsev kho mob, vim lawv tso cai rau kev tshawb pom sai ntawm kev rov qab los qeeb lossis cov xwm txheej tsis zoo.
Vim li cas cov cim ceeb toom tseem ceeb?
Lub ntsiab tseem ceeb ntawm kev nthuav qhia Kev Nyab Xeeb yog txhawm rau tiv thaiv kev raug mob thiab xyuas kom cov neeg ua haujlwm thiab cov neeg tuaj saib paub zoo txog kev phom sij thiab kev phom sij ua ntej hauv qee qhov xwm txheej thiab / lossis ib puag ncig .
Vim li cas qhov tseem ceeb yog qhov tseem ceeb?
Nws yuav tsum muaj lub zog lub cev thiab lub siab lub ntsws. Qhov tseem ceeb yog qhov tseem ceeb uas tso cai rau koj mus txuas ntxiv thiab ua lub neej zoo. Hauv qhov tseem ceeb, qhov tseem ceeb txhais tau hais tias muaj zog, noj qab nyob zoo, thiab muaj txiaj ntsig zoo.
