Yog. Yog tias koj yog ib lub khw muag khoom me me lossis pib ua lag luam, peb yeej txaus siab loj hlob nrog koj. Thiab peb tab tom nrhiav rau pem hauv ntej kom ua haujlwm nrog koj rau kev sib raug zoo mus sij hawm ntev.

Tus nqi li cas? Koj puas ua tau kom pheej yig dua?

Peb yeej ib txwm xav txog qhov zoo ntawm cov neeg siv khoom ua qhov tseem ceeb tshaj plaws. Tus nqi tuaj yeem sib tham tau raws li ntau yam xwm txheej, peb paub tseeb tias koj yuav tau txais tus nqi sib tw tshaj plaws.

Koj puas muab cov qauv dawb?

Zoo siab uas koj sau tau cov kev tshuaj xyuas zoo rau peb yog tias koj nyiam peb cov khoom thiab kev pabcuam, peb yuav muab qee cov qauv dawb rau koj ntawm koj qhov kev txiav txim tom ntej.

Koj puas xa tau raws sijhawm?

Tau kawg! peb tshwj xeeb hauv kab no tau ntau xyoo, ntau tus neeg siv khoom ua ib daim ntawv cog lus nrog kuv vim peb tuaj yeem xa cov khoom raws sijhawm thiab khaws cov khoom zoo tshaj plaws!

Kuv puas tuaj yeem mus xyuas koj lub tuam txhab thiab lub Hoobkas hauv Suav teb?

Tseeb. Koj zoo siab tos txais koj tuaj xyuas peb lub tuam txhab hauv Zibo, Suav teb. (1.5H tsav tsheb los ntawm Jinan)

Kuv tuaj yeem tso qhov kev txiav txim li cas?

Koj tuaj yeem xa peb cov lus nug rau ib tus neeg sawv cev muag khoom kom tau txais cov ntaub ntawv qhia txog kev txiav txim, thiab peb yuav piav qhia txog cov txheej txheem kom ntxaws. Sodium formate Chromatographic Conditions thiab System Configuration
Tom qab kev ua kom zoo dua, cov xwm txheej kev txiav txim siab ib txwm muaj nyob hauv qab no. Cov kws tshuaj ntsuam xyuas yuav ua qhov kev hloov kho me me raws li qhov kev ua tau zoo ntawm cov cuab yeej thiab kem.
Rau theem mobile, siv cov khoom sib xyaw ntawm 20 mM potassium dihydrogen phosphate buffer (kho kom haum pH 3.0) thiab methanol hauv qhov sib piv ntawm 95:5. Cov buffer yuav tsum tau lim los ntawm daim nyias nyias 0.45 µm thiab degassed tag nrho ua ntej siv, vim pH cuam tshuam rau ob qho tib si zoo nkauj thiab lub sijhawm khaws cia.
Siv ib lub reversed-phase C18 kem uas muaj qhov ntev li 250 mm × 4.6 mm thiab qhov loj ntawm cov khoom me me li 5 µm. Xyuas kom lub kem zoo thiab ua tau raws li cov lus qhia txog kev ua haujlwm zoo. Tus nqi ntws yog teem rau qhov tas li 1.0 mL/min, thiab qhov kub ntawm lub kem yog tswj ntawm 30°C, uas tuaj yeem hloov kho tau hauv qhov ntau ntawm 25–40°C kom ntseeg tau tias kev tshuaj xyuas ruaj khov.
Kev kuaj pom yog ua tiav ntawm qhov ntev ntawm 210 nm, qhov twg sodium formate qhia txog qhov kawg nqus. Xyuas kom tseeb tias lub teeb deuterium ntawm lub tshuab ntes muaj zog txaus rau kev ntsuas qhov tseeb. Qhov ntim txhaj tshuaj yog 10 µL; kev siv lub tshuab kuaj tsis siv neeg yog qhov pom zoo, thiab kev txhaj tshuaj tes yuav tsum tau ua tib zoo saib xyuas kev ua haujlwm.
