tlhaloso e khuts'oane:

Re fana ka mefuta e 'meli ea li-cartridge tsa li-valve tsa ho hlahloba, cartridge ea ruby ​​check valve le cartridge ea ceramic check valve. Li-cartridges tsena tsa li-valve tsa ho hlahloba li lumellana le mekhahlelo eohle ea LC mobile. 'Me li ka kenngoa ka har'a pompo ea Metsi 'me tsa sebelisoa hammoho, e le li-valve tse kenang ka har'a Waters 1515, 1525, 2695D, E2695 le 2795 pump.

    Nako ea ho fetola valve ea ho hlahloba?
    ① "Lost Prime" e hlahang ha sistimi e sebetsa e bontša hore khatello ea sistimi e tlase haholo, e tlase haholo ho feta khatello ea morao e hlokahalang bakeng sa ts'ebetso ea kamehla ea mokelikeli oa chromatography. Haholo-holo e bakoa ke ho silafatsoa ha valve ea ho hlahloba hloohong ea pompo, kapa li-bubble tse nyenyane tse setseng ka har'a valve e lebisang ho infusion e sa tsitsang. Ka nako ena, seo re hlokang ho se etsa ke ho leka ho hlakola li-bubble tse nyane ka ts'ebetso ea metsotso e mehlano ea "Wet Prime". Haeba tharollo ena e hlōleha, re lokela ho tlosa valve ea ho hlahloba, 'me re e hloekise ka ultrasonically ka metsi a ka holimo ho 80 ℃. Ho kgothaletswa ho fetola cartridge ea valve haeba ho hloekisa khafetsa ho sa sebetse.

    ② Ho ile ha fumaneha hore ho na le lipompong hloohong ea pompo kapa valve ea ho hlahloba ha khatello ea sistimi e fetoha haholo. Re ka sebetsa "Wet Prime" bakeng sa metsotso e 5-10, ho hlatsoa li-bubble ka sekhahla se phahameng sa phallo. Haeba mokhoa o ka holimo o sa sebetse, re tlameha ho tlosa valve ea ho hlahloba, ebe re e hloekisa ka ultrasonically ka metsi a ka holimo ho 80 ℃. Ho kgothaletswa ho fetola cartridge ea valve haeba ho hloekisa khafetsa ho sa sebetse.

    ③ Ha ho na le bothata ba ho hlahisa ente ea sistimi, qala ka ho hlokomela nako ea ho boloka. Haeba ho na le bothata ka nako ea ho boloka, hlahloba ho fetoha ha khatello ea tsamaiso ho tloaelehile kapa che. Ka tloaelo, ka tekanyo ea phallo ea 1ml / min, khatello ea tsamaiso ea sesebelisoa e lokela ho ba 2000 ~ 3000psi. (Ho na le liphapang tsa karo-karolelano ho latela mefuta ea likholomo tsa chromatographic le mekhahlelo ea mehala.) Ke ntho e tloaelehileng hore ho feto-fetoha ha khatello ho ka har'a 50psi. Phetoho e leka-lekaneng le e ntle ea khatello ea tsamaiso e ka hare ho 10psi. Tlas'a boemo ba hore khatello ea khatello e kholo haholo, re lokela ho nahana ka monyetla oa hore valve ea ho hlahloba e silafalitsoe kapa e na le li-bubble, ebe e sebetsana le eona.

    U ka sebelisa valve ea ho hlahloba ka ceramic neng?
    Ho na le bothata ba ho lumellana pakeng tsa ruby ​​check valve ea 2690/2695 le mefuta e itseng ea acetonitrile. Boemo bo tobileng ke: ha u sebelisa 100% acetonitrile, u e siea bosiu bo le bong, 'me u tsoela pele ho qala liteko letsatsing le hlahlamang, ha ho na mokelikeli o tsoang pompong. Lebaka ke hore 'mele oa ruby ​​check valve le bolo ea ruby ​​li khomaretsoe hammoho ka mor'a hore li kene ka har'a acetonitrile e hloekileng. Re lokela ho tlosa valve ea ho hlahloba ebe re e kokota hanyenyane kapa re tšoara ultrasonically. Ha u sisinya valve ea ho hlahloba le ho utloa molumo o fokolang, sena se bolela hore valve ea ho hlahloba e khutlela ho tloaelehileng. Joale khutlisetsa valve ea ho hlahloba. Hangata liteko li ka etsoa kamora metsotso e 5 "Wet Prime".

    Ho qoba bothata bona litekong tse latelang, ho kgothaletswa ho sebelisa valve ea ho hlahloba ka ceramic.
