Thaum twg los hloov daim tshev valve?
① "Lost Prime" tshwm sim thaum lub kaw lus khiav qhia tias lub kaw lus siab qis dhau, qis dua qhov rov qab siab xav tau rau kev ua haujlwm ua kua chromatography. Nws feem ntau yog tshwm sim los ntawm kev sib kis ntawm daim tshev valve hauv lub taub hau twj tso kua mis, lossis cov npuas me me tseem nyob hauv daim tshev valve ua rau cov dej tsis huv. Lub sijhawm no, peb yuav tsum ua li cas yog txhawm rau txhawm rau tshem tawm cov npuas me me los ntawm kev ua haujlwm tsib feeb ntawm "Wet Prime". Yog tias cov tshuaj no ua tsis tiav, peb yuav tsum tshem tawm daim tshev valve, thiab ntxuav nws ultrasonically nrog dej saum 80 ℃. Nws raug nquahu kom hloov daim tshev valve cartridge yog tias rov ua dua tshiab tsis zoo.

② Nws hloov tawm hais tias muaj npuas nyob rau hauv lub taub hau twj tso kua mis los yog kos valve thaum lub zog siab fluctuates heev. Peb tuaj yeem ua haujlwm "Wet Prime" rau 5-10 feeb, txhawm rau yaug cov npuas nrog cov dej ntws siab. Yog hais tias txoj kev saum toj no tsis ua haujlwm, peb yuav tsum tshem tawm daim tshev valve, thiab ntxuav nws ultrasonically nrog dej saum 80 ℃. Nws raug nquahu kom hloov daim tshev valve cartridge yog tias rov ua dua tshiab tsis zoo.

③ Thaum muaj teeb meem nrog kev txhaj tshuaj tiv thaiv kab mob, ua ntej saib xyuas lub sijhawm khaws cia. Yog tias muaj teeb meem nrog lub sijhawm khaws cia, xyuas qhov hloov pauv ntawm qhov system siab yog qhov qub lossis tsis yog. Nquag, ntawm tus nqi ntws ntawm 1ml / min, qhov ntsuas qhov system siab yuav tsum yog 2000 ~ 3000psi. (Muaj qhov sib txawv ntawm qhov sib txawv nyob ntawm hom chromatographic kab thiab theem mobile.) Nws yog ib txwm muaj qhov hloov pauv siab nyob rau hauv 50psi. Qhov sib npaug thiab zoo zog siab hloov pauv yog nyob rau hauv 10psi. Nyob rau hauv cov xwm txheej uas qhov kev hloov pauv siab loj dhau lawm, peb yuav tsum xav txog qhov muaj peev xwm tias cov tshev valve muaj kab mob lossis muaj npuas, tom qab ntawd nrog nws.

Thaum twg siv ceramic check valve?
Muaj qhov teeb meem kev sib raug zoo ntawm ruby kos valve ntawm 2690/2695 thiab qee hom ntawm acetonitrile. Qhov xwm txheej tshwj xeeb yog: thaum siv 100% acetonitrile, tawm hauv ib hmos, thiab txuas ntxiv pib sim rau hnub tom qab, tsis muaj kua tawm ntawm lub twj tso kua mis. Qhov no yog vim lub ruby kos valve lub cev thiab ruby pob tau muab lo ua ke tom qab soaking rau hauv cov ntshiab acetonitrile. Peb yuav tsum tshem tawm cov tshev valve thiab maj mam khob nws los yog kho ultrasonically. Thaum co lub check valve thiab hnov ib lub suab me ntsis, qhov no txhais tau hais tias lub check valve rov zoo li qub. Tam sim no muab lub check valve rov qab. Cov kev sim no tuaj yeem ua tiav tom qab 5-feeb "Wet Prime".

Txhawm rau zam qhov teeb meem no hauv kev sim hauv qab no, nws raug nquahu kom siv ceramic check valve.

Nta

1. Tau tshaj txhua theem LC mobile.
2. Kev ua tau zoo heev.
