Ana ba da shawarar maye gurbin cak ɗin bawul ɗin duba idan maimaita tsaftacewa ba ta da tasiri.

③ Lokacin da aka sami matsala tare da sake haifar da allurar tsarin, da farko kiyaye lokacin riƙewa. Idan akwai matsala tare da lokacin riƙewa, duba jujjuyawar matsa lamba tsarin al'ada ne ko a'a. A al'ada, a cikin adadin 1ml / min, tsarin tsarin kayan aiki ya kamata ya zama 2000 ~ 3000psi. (Akwai bambance-bambancen rabo dangane da nau'ikan ginshiƙan chromatographic da matakan wayar hannu.) Yana da al'ada cewa saurin matsa lamba yana cikin 50psi. Daidaitaccen madaidaicin tsarin matsi mai kyau yana cikin 10psi. A ƙarƙashin yanayin cewa canjin matsa lamba ya yi girma, muna buƙatar yin la'akari da yiwuwar cewa bawul ɗin duba ya gurɓata ko yana da kumfa, sannan mu magance shi.

Yaushe za a yi amfani da bawul ɗin duba yumbu?
Akwai batun daidaitawa tsakanin ruby ​​check valve na 2690/2695 da wasu nau'ikan acetonitrile. Musamman halin da ake ciki shine: lokacin amfani da 100% acetonitrile, barin shi cikin dare, kuma ci gaba da fara gwaje-gwaje a rana mai zuwa, babu wani ruwa da ke fitowa daga famfo. Wannan saboda an manne jikin jikin ruby ​​check valve da ƙwallon ruby ​​bayan an jiƙa cikin tsantsar acetonitrile. Ya kamata mu cire bawul ɗin rajistan kuma mu buga shi da sauƙi ko bi da ultrasonically. Lokacin girgiza bawul ɗin dubawa da jin ƙaramar sauti, wannan yana nufin bawul ɗin rajistan ya dawo daidai. Yanzu mayar da bawul ɗin duba. Ana iya yin gwaje-gwaje akai-akai bayan mintuna 5 "Wet Prime".
