Hāʻawi mākou i ʻelua ʻano pahu pahu pahu pahu, pahu pahu pahu pahu ruby ​​​​a me pahu pahu pahu pahu ceramic. Ua kūpono kēia mau pahu pahu pahu pahu me nā LC āpau āpau. A hiki iā lākou ke hoʻokomo ʻia i loko o ka pā wai a hoʻohana pū ʻia, e like me ke pani pani i loko o ka wai 1515, 1525, 2695D, E2695 a me 2795 pump.

    ʻO ka manawa hea e pani ai i ka valve check?
    ① Hōʻike ʻia ka "Lost Prime" i ka wā e holo ai ka ʻōnaehana i ka haʻahaʻa loa o ke kaomi ʻōnaehana, ʻoi aku ka haʻahaʻa ma mua o ke kaomi hope e pono ai no ka hana chromatography wai maʻamau. Ma muli o ka hoʻohaumia ʻana o ka valve check ma ke poʻo o ka paila, a i ʻole nā ​​ʻōpala liʻiliʻi i waiho ʻia i loko o ka valve check e alakaʻi ana i ka infusion ʻole. I kēia manawa, ʻo ka mea e pono ai mākou e hana, ʻo ia ka hoʻāʻo e hoʻomaʻemaʻe i nā ʻōpū liʻiliʻi ma o ka hana ʻelima mau minuke o "Wet Prime". Inā hāʻule kēia hāʻina, pono mākou e wehe i ka valve check, a hoʻomaʻemaʻe me ka ultrasonically me ka wai ma luna o 80 ℃. Manaʻo ʻia e hoʻololi i ka pahu pahu pahu pahu inā ʻaʻole pono ka hoʻomaʻemaʻe pinepine ʻana.

    ② Ua ʻike ʻia aia nā ʻōhū i loko o ke poʻo o ka paila a i ʻole ka valve nānā ke piʻi nui ka neʻe ʻana o ka ʻōnaehana. Hiki iā mākou ke hana i ka "Wet Prime" no 5-10 mau minuke, e holoi i nā ʻōhū me kahi kahe kiʻekiʻe. Inā ʻaʻole holo ka hana ma luna, pono mākou e wehe i ka valve check, a hoʻomaʻemaʻe i ka ultrasonically me ka wai ma luna o 80 ℃. Manaʻo ʻia e hoʻololi i ka pahu pahu pahu pahu inā ʻaʻole pono ka hoʻomaʻemaʻe pinepine ʻana.

    ③ Inā loaʻa ka pilikia me ka hana hou ʻana o ka ʻōnaehana injection, e nānā mua i ka manawa paʻa. Inā pilikia ka manawa paʻa, e nānā i ka loli o ke kaomi ʻōnaehana maʻamau a ʻaʻole paha. ʻO ka maʻamau, ma ke kahe kahe o 1ml / min, pono ke kaomi ʻana o ka ʻōnaehana ʻo 2000 ~ 3000psi. (Aia nā ʻokoʻa lākiō ma muli o ke ʻano o nā kolamu chromatographic a me nā ʻāpana kelepona.) He mea maʻamau ka piʻi ʻana o ke kaomi i loko o 50psi. ʻO ke kaulike a me ka maikaʻi o ka neʻe ʻana o ka ʻōnaehana i loko o 10psi. Ma lalo o ke ʻano he nui loa ka piʻi ʻana o ke kaomi, pono mākou e noʻonoʻo i ka hiki ke hoʻohaumia ʻia ka valve check a loaʻa paha nā ʻūhū, a laila e hana me ia.

    I ka manawa hea e hoʻohana ai i ka valve check ceramic?
    Aia kahi pilikia kūpono ma waena o ka ruby ​​check valve o 2690/2695 a me kekahi mau ʻano o ka acetonitrile. ʻO ke kūlana kikoʻī: i ka wā e hoʻohana ai i ka 100% acetonitrile, waiho ʻia i ka pō, a hoʻomau i ka hoʻomaka ʻana i nā hoʻokolohua i ka lā aʻe, ʻaʻohe wai e puka mai i waho o ka paila. ʻO kēia no ka mea ua hoʻopili pū ʻia ke kino o ka pahu ruby ​​check valve a me ka poepoe ruby ​​​​ma hope o ke komo ʻana i loko o ka acetonitrile maʻemaʻe. Pono mākou e hoʻoneʻe i ka pahu hoʻopaʻa a kikeke māmā iā ia a i ʻole e mālama i ka ultrasonically. Ke hoʻoluliluli i ka pahu pahu a lohe i kahi kani liʻiliʻi, ʻo ia ke ʻano o ka hoʻi ʻana o ka pahu pahu i ka maʻamau. I kēia manawa, e hoʻihoʻi hou i ka valve check. Hiki ke hana maʻamau nā hoʻokolohua ma hope o 5 mau minuke "Wet Prime".

    No ka pale ʻana i kēia pilikia ma ka hahai ʻana i nā hoʻokolohua, pono e hoʻohana i ka valve check ceramic.
