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.
