Liquid chromatography cheki vharafu ruby ​​ceramic mvura kutsiva

Nguva yekutsiva cheki vharafu?
① "Yarasika Prime" inooneka kana sisitimu ichimhanya inoratidza kudzvanywa kwehurongwa kwakadzikira, kuderera zvakanyanya pane kudzvinyirirwa kumashure kunodiwa kuti ugare uchiita chromatography yemvura.Iyo inonyanya kukonzerwa nekusvibiswa kwevhavhavha yekuongorora mumusoro wepombi, kana mabhuru maduku akasara muvhavhavhavha inoenda kune unsmooth infusion.Panguva ino, chatinofanira kuita ndechekuedza kubvisa mabhuru madiki kuburikidza nemaminetsi mashanu ekushanda kwe "Wet Prime".Kana mhinduro iyi ikatadza, isu tinofanirwa kubvisa cheki valve, uye kuichenesa ultrasonically nemvura inopfuura 80 ℃.Zvinokurudzirwa kutsiva cheki valve cartridge kana kudzokorora kucheneswa kusingabatsiri.

② Zvinoitika kuti kune mabubble mumusoro wepombi kana cheki vharafu kana system yekumanikidza ichichinja zvakanyanya.Tinogona kushanda "Wet Prime" kwemaminetsi 5-10, kushambidza mabhubhu nehuwandu hwekuyerera.Kana nzira iri pamusoro isingashande, isu tinofanirwa kubvisa cheki valve, uye kuichenesa ultrasonically nemvura inopfuura 80 ℃.Zvinokurudzirwa kutsiva cheki valve cartridge kana kudzokorora kucheneswa kusingabatsiri.

③ Kana paine dambudziko nesystem jekiseni reproducibility, tanga waona nguva yekuchengeta.Kana paine dambudziko nekuchengetedza nguva, tarisa kuchinjika kwehurongwa hwekumanikidza kwakajairika kana kwete.Kazhinji, pachiyero chekuyerera kwe1ml / min, chiridzwa chechirongwa chekumanikidza chinofanira kunge chiri 2000 ~ 3000psi.(Kune reshiyo misiyano zvichienderana nemhando dzekromatographic columns uye mobile phases.) Zvinowanzoitika kuti pressure fluctuation iri mukati me50psi.Iyo yakadzikama uye yakanaka system kudzvanywa kushanduka kuri mukati me10psi.Pasi pemamiriro ekuti kudzvinyirirwa kwakakurisa, isu tinofanirwa kufunga nezve mukana wekuti cheki vharafu yakasvibiswa kana ine mabhubhu, wozobata nayo.

Ndeipi nguva yekushandisa ceramic cheki vharafu?
Pane nyaya yekuenderana pakati peruby check valve ye2690/2695 uye mamwe mabrande eacetonitrile.Mamiriro ezvinhu chaiwo ndeokuti: kana uchishandisa 100% acetonitrile, uchiisiya usiku hwose, uye uchiramba uchitanga kuedza zuva rinotevera, hapana mvura inobuda papombi.Izvi zvinodaro nekuti iyo ruby ​​​​cheki vharafu muviri uye ruby ​​bhora zvakanamatirwa pamwechete mushure mekunyura mune yakachena acetonitrile.Tinofanira kubvisa cheki valve uye zvishoma kugogodza iyo kana kubata ultrasonically.Paunenge uchizunungusa cheki vharafu uye uchinzwa ruzha rudiki, izvi zvinoreva kuti cheki valve inodzokera kune yakajairika.Zvino isa cheki vharuvhu kumashure.Iwo maedzo anogona kazhinji kuitwa mushure memaminitsi mashanu "Wet Prime".

Kuti udzivise dambudziko iri mukutevera miedzo, zvinokurudzirwa kushandisa ceramic cheki vharafu.
