Liquid chromatography chekeni valavu ruby ceramic madzi m'malo

Kufotokozera mwachidule:

Timapereka ma valavu amitundu iwiri, valavu ya cheke ya ruby ndi valavu ya ceramic.Ma valve cheke awa amagwirizana ndi magawo onse amtundu wa LC.Ndipo amatha kukhazikitsidwa mu mpope wa Madzi ndikugwiritsidwa ntchito limodzi, monga mavavu olowera m'malo mu Waters 1515, 1525, 2695D, E2695 ndi 2795 mpope.

Ndi liti pamene mungalowe m'malo valavu?
① "Lost Prime" yomwe imawoneka ikamayenda imawonetsa kuti kukakamiza kwadongosolo ndikotsika kwambiri, kutsika kwambiri kuposa kupanikizika kwam'mbuyo komwe kumafunikira kuti pakhale chromatography yamadzimadzi pafupipafupi.Zimayamba chifukwa cha kuipitsidwa kwa valavu yoyang'ana pamutu wa pampu, kapena tinthu tating'onoting'ono totsalira mu valavu yopita ku kulowetsedwa kosasunthika.Panthawiyi, zomwe tikuyenera kuchita ndikuyesa kuchotsa tinthu tating'onoting'ono pogwiritsa ntchito mphindi zisanu za "Wet Prime".Ngati yankho lalephera, tikuyenera kuchotsa valavu yoyang'ana, ndikuyiyeretsa ndi madzi opitilira 80 ℃.Ndibwino kuti m'malo cheke valavu katiriji ngati kuyeretsa mobwerezabwereza sikuthandiza.

② Zikuwonekeratu kuti pali thovu pamutu wapampu kapena valavu yowunika pamene kupanikizika kwa dongosolo kumasinthasintha kwambiri.Titha kugwiritsa ntchito "Wet Prime" kwa mphindi 5-10, kuti mutsuka thovulo ndi kuthamanga kwambiri.Ngati njira yomwe ili pamwambayi siyikugwira ntchito, tikuyenera kuchotsa valavu yoyang'ana, ndikuyiyeretsa ndi madzi opitilira 80 ℃.Ndibwino kuti m'malo cheke valavu katiriji ngati kuyeretsa mobwerezabwereza sikuthandiza.

③ Pakakhala vuto ndi kubwezeredwa kwa jakisoni, choyamba yang'anani nthawi yosungira.Ngati pali vuto ndi nthawi yosungira, yang'anani kusinthasintha kwa kupanikizika kwa dongosolo ndikwachilendo kapena ayi.Nthawi zambiri, pakuyenda kwa 1ml / min, kuthamanga kwa chipangizocho kuyenera kukhala 2000 ~ 3000psi.(Pali kusiyana kwa chiŵerengero kutengera mitundu ya mizati ya chromatographic ndi magawo a mafoni.) Ndizodziwika kuti kusinthasintha kwamphamvu kumakhala mkati mwa 50psi.Kusinthasintha kwadongosolo komanso kusinthasintha kwadongosolo kumakhala mkati mwa 10psi.Pansi pa zomwe kusinthasintha kwamphamvu ndi kwakukulu kwambiri, tiyenera kulingalira kuti valavu yowunika yawonongeka kapena ili ndi thovu, ndiye thana nayo.

Ndi liti pamene mungagwiritse ntchito valavu ya ceramic?
Pali vuto logwirizana pakati pa ruby check valve ya 2690/2695 ndi mitundu ina ya acetonitrile.Mkhalidwe weniweni ndi: mukamagwiritsa ntchito 100% acetonitrile, kusiya usiku wonse, ndikupitirizabe kuyesa tsiku lotsatira, palibe madzi omwe amatuluka pampu.Izi zili choncho chifukwa thupi la ruby check valve ndi mpira wa ruby zalumikizidwa pamodzi pambuyo poviika mu acetonitrile yoyera.Tiyenera kuchotsa valavu cheke ndi mopepuka kugogoda kapena kuchiza ultrasonically.Mukagwedeza valavu yoyang'ana ndikumva phokoso laling'ono, izi zikutanthauza kuti valavu yowunikira imabwerera mwakale.Tsopano bweretsani valavu yoyang'ana kumbuyo.Kuyesako kumatha kuchitika pakadutsa mphindi 5 "Wet Prime".

Pofuna kupewa vutoli potsatira zoyeserera, tikulimbikitsidwa kugwiritsa ntchito valavu ya ceramic.

Mawonekedwe

1. Yogwirizana ndi magawo onse a LC mafoni.
2. Kuchita bwino kwambiri.
