Kev tsom xam chromatographic yog ib qho cuab yeej tseem ceeb rau ntau qhov kev lag luam, los ntawm kev siv tshuaj mus rau ib puag ncig kev sim. Txawm li cas los xij, ib qho kev sib tw feem ntau cuam tshuam cov txiaj ntsig tseeb - dab ntxwg nyoog peaks. Cov peaks uas tsis paub meej no ua rau nyuaj rau kev soj ntsuam, tsis pom cov ntaub ntawv tseem ceeb, thiab xav tau sijhawm ntxiv thiab siv zog rau kev daws teeb meem. Hauv tsab xov xwm no, peb qhia tusDab-Sniper Kem, ib tug revolutionary tov tsim los tshem tawm dab peaks thiab txhim kho chromatographic kev ua tau zoo.
Dab Peaks yog dab tsi, thiab Vim Li Cas Lawv Tseem Ceeb?
Dab peaks yog cov ncov tsis paub uas tshwm sim ntawm chromatograms thaum sib cais, tshwj xeeb tshaj yog nyob rau hauv gradient txoj kev. Lawv tuaj yeem cuam tshuam los ntawm ntau qhov chaw: kev sib kis kab mob (xws li, huab cua npuas, qias neeg injector koob), residual contamination nyob rau hauv kem, los yog impurities nyob rau hauv lub mobile theem los yog cov qauv ntim. Dab peaks feem ntau sib tshooj nrog lub hom phiaj ntsuas peaks, ua rau kom muaj nuj nqis tsis raug thiab lub sijhawm tshuaj xyuas ntxiv.
Ib txoj kev tshawb fawb luam tawm hauvPhau ntawv Journal of Chromatographic Sciencetaw qhia tias dab peaks ua rau kwv yees li 20% ntawm chromatographic tsom xam qeeb, underlining lawv cuam tshuam rau kev ua haujlwm hauv chav kuaj. Kev daws qhov teeb meem no yog qhov tseem ceeb rau kev txhim khu kev qha thiab rov tsim dua tshiab.
Txoj Kev: Dab-Sniper Kab
Dab Ntxwg Nyoog-Sniper Kem muab txoj hauv kev tsom mus rau kev tshem tawm dab peaks ua ntej lawv mus txog qhov txhaj tshuaj, tiv thaiv koj qhov kev soj ntsuam kev ncaj ncees. Nruab nruab nrab ntawm cov khoom sib tov thiab cov tshuaj txhaj tshuaj, cov kab ke ua lub lim kom ntes cov kab mob, muab cov kab mob chromatographic huv si. Nws qhov kev ua tau zoo tau ua rau nws muaj kev ntseeg siab ntawm cov kws tshuaj ntsuam thoob ntiaj teb.
Nws Ua Haujlwm Li Cas?
•Contaminant Capture:Dab Ntxwg Nyoog-Sniper Kem cuam tshuam cov impurities los ntawm lub xov tooj ntawm tes, buffers, lossis residual organic pollutants, kom ntseeg tau tias lawv tsis cuam tshuam nrog chromatographic sib cais.
•Cov cuab yeej tiv thaiv:Los ntawm kev lim cov khoom thiab cov kab mob, nws tiv thaiv ob lub cuab yeej thiab cov kab kev tshuaj ntsuam thawj zaug, ncua lawv txoj sia thiab tswj kev ua haujlwm.
•Enhanced Efficiency:Cov kws tshuaj ntsuam xyuas txuag lub sijhawm los ntawm kev zam kev daws teeb meem rov qab thiab hloov kho los ntawm dab peaks.
Optimizing Koj Workflow nrog Dab-Sniper Kab
Txhawm rau kom tau txais txiaj ntsig zoo tshaj plaws ntawm Ghost-Sniper Kem, ua raws li cov kev coj ua zoo tshaj plaws no:
1.Kev teeb tsa: Muab cov kab nruab nrab ntawm lub tshuab tov khoom thiab cov tshuaj txhaj tshuaj. Xyuas kom cov qauv kev daws teeb meem tsis ntws los ntawm kab ke kom tswj tau nws txoj haujlwm.
2.Kev npaj ua ntej siv: Rau cov kab tshiab, yaug nrog 100% acetonitrile ntawm tus nqi ntws ntawm 0.5 mL / min rau 4 teev kom ntseeg tau tias kev ua haujlwm zoo.
3.Kev tu txhua hnub: Hloov cov kem tsis tu ncua raws li kev soj ntsuam cov xwm txheej, xws li cov theem ntawm lub xov tooj ntawm tes thiab cov khoom siv huv.
4.Cia: Yog tias tsis siv rau lub sijhawm ntev, khaws cov kab hauv 70% methanol lossis acetonitrile tov kom khaws nws txoj kev ncaj ncees.
5.Kev txiav txim siab tshwj xeeb: Tsis txhob siv ion-pair reagents nyob rau hauv lub sij hawm mobile nrog kem, raws li lawv tej zaum yuav cuam tshuam rau lub sij hawm tuav thiab ncov zoo.
Cov yam ntxwv tseem ceeb ntawm Dab-Sniper Kab
Ghost-Sniper Kem muaj nyob rau hauv ntau qhov ntev kom haum rau cov kev xav tau sib txawv:
•50 × 4.6 hlirau HPLC daim ntawv thov uas muaj kwv yees li ntawm 800 μL.
•35 × 4.6mmthiab30 × 4.0 hlirau qis-kem-ntim HPLC.
•50 × 2.1 hliUPLC yog tsim rau UPLC nrog kwv yees li ntawm 170 μL.
Txhua kab yog tsim los xa cov kev ua tau zoo tsis sib xws, ua kom muaj cov txheej txheem chromatographic huv thiab txhim khu kev qha.
