M'dziko la high-performance liquid chromatography (HPLC), kusankha chubu loyenera ndikofunikira kuti mukwaniritse zolondola, zodalirika. Chimodzi mwazinthu zodziwika komanso zothandiza zomwe zilipo ndiChithunzi cha PEEK, zomwe zimagwira ntchito yofunika kwambiri powonetsetsa kuti kusanthula kwamankhwala kukuchitika molondola kwambiri. M'nkhaniyi, tiwona chifukwa chake machubu a PEEK ali chisankho chabwino kwambiri kwa akatswiri a labotale komanso momwe kusankha kukula koyenera ndi mawonekedwe angakwezere kuyesa kwanu kwamadzimadzi a chromatography.
Chifukwa chiyani PEEK Tubing Ndi Yofunika kwa HPLC
High-Performance Liquid Chromatography (HPLC) ndi njira yaukadaulo yowunikira yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikiza mankhwala, kuyang'anira chilengedwe, komanso chitetezo cha chakudya. Pakuwunika kwa HPLC, ma reagents amapopedwa pamphamvu kwambiri kudzera mudongosolo, zomwe zimayika kupsinjika kwakukulu pamachubu. Izi zimapangitsa kukhala kofunikira kugwiritsa ntchito machubu omwe ali amphamvu, osamva mankhwala, komanso omwe amatha kupirira kutentha kwambiri.
PEEK chubu, ndi mphamvu zake zamakina komanso kukana kwamankhwala, idapangidwa kuti ikwaniritse zofunikira izi. Imalimbana ndi zokakamiza mpaka 300bala, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pamapulogalamu a HPLC. Komanso, PEEK (Polyetheretherketone) sichichotsa ma ion zitsulo, kuonetsetsa kuti kusanthula kumakhalabe kopanda kuipitsidwa, komwe kuli kofunikira pakuwunika komwe kulondola kuli chilichonse.
Zofunika Kwambiri za 1/16 ”PEEK Tubing
Malingaliro a kampani Maxi Scientific Instruments (Suzhou) Co., Ltd.amapereka1/16" PEEK chubumu makulidwe osiyanasiyana, kukulolani kuti musankhe chubu chomwe chikugwirizana bwino ndi khwekhwe lanu la HPLC. M'mimba mwake (OD) ya chubu ndi 1/16" (1.58 mm), kukula kwake komwe kumagwirizana ndi machitidwe ambiri a HPLC. Zosankha zamkati zamkati (ID) zikuphatikizapo 0.13mm, 0.18mm, 0.25mm, 0.5mm, 0.75mm, ndi 1mm, zomwe zimakupatsirani zosankha zambiri zamitundu yosiyanasiyana yothamanga ndi ntchito.
PEEK chubu yochokera ku Maxi Scientific Instruments imadziwika chifukwa chololera kwambiri± 0.001” (0.03mm)kwa ma diameter amkati ndi akunja, kuwonetsetsa kusasinthika mukuchita. Kulondola uku ndikofunikira pazotsatira zodalirika za HPLC, pomwe kusiyanasiyana pang'ono kumatha kukhudza kusanthula. Kuphatikiza apo, pakuyitanitsa machubu a PEEK5 mita,achodulira chubu chaulereamaperekedwa, zomwe zimapangitsa kudula chubu kwa kutalika komwe mukufuna kukhala kosavuta komanso kolondola.
Ubwino Wogwiritsa Ntchito PEEK Tubing mu HPLC
1. High Pressure Resistance: PEEK chubu idapangidwa makamaka kuti ikhale yolimba kwambiri, ndikupangitsa kuti ikhale yabwino kwa mapulogalamu a HPLC pomwe ma reagents amapopedwa mopanikizika kwambiri. Imasunga umphumphu wake pansi pa milingo yokakamiza mpaka400 bar, kuonetsetsa kuti ikuyenda bwino komanso yosasokonezeka panthawi yofufuza.
2. Kukaniza Chemical: Chimodzi mwazinthu zodziwika bwino za PEEK chubing ndi kukana kwapadera kwa mankhwala. Imatha kuthana ndi zosungunulira zosiyanasiyana, kuphatikiza ma acid, mabasi, ndi zosungunulira za organic, popanda kutsitsa kapena kutulutsa zowononga zowononga m'dongosolo. Izi zimapangitsa kukhala koyenera pakuwunika kwamankhwala komwe kumafunikira chiyero ndi kulondola.
3. Kutentha Kukhazikika: PEEK tubing imakhalanso yochititsa chidwimalo osungunuka a 350 ° C, kupangitsa kuti ikhale yolimbana ndi kutentha kwakukulu komwe kungachitike panthawi yowunika kwa nthawi yayitali kapena kutentha kwambiri. Kukana kutentha kumeneku kumapangitsa kuti chubu likhalebe likugwira ntchito ngakhale kumalo otentha kwambiri, kumapereka kudalirika pazochitika zosiyanasiyana zoyesera.
4. Kugwirizana ndi Finger-Tight Fittings: Machubu a PEEK adapangidwa kuti azigwira ntchito mosasunthika ndi zolumikizira zala, kupereka kulumikizana kosavuta komanso kothandiza popanda kufunikira kwa zida zovuta. Chosavuta kugwiritsa ntchitochi chimapangitsa kukhala kosavuta kukhazikitsa ndi kukonza dongosolo lanu la HPLC.
5. Mitundu Yamitundu Yosavuta Kuzindikiritsa: Tubing ya PEEK imakhala ndi mitundu yotengera kukula kwamkati (ID) kuti ithandizire kuzindikira mosavuta. Ngakhale inki ikhoza kutha ndikugwiritsa ntchito, sizikhudza momwe chubu likuyendera, kuwonetsetsa kuti mutha kudalirabe pakusanthula kwanu.
Zomwe Muyenera Kupewa Mukamagwiritsa Ntchito PEEK Tubing
Ngakhale machubu a PEEK amalimbana kwambiri ndi mankhwala osiyanasiyana, pali zina.Anayikira sulfuric asidindikuchuluka kwa nitric acidakhoza kuwononga chubu, choncho ayenera kupewa. Kuphatikiza apo, machubu a PEEK amatha kukula akakumana ndi zosungunulira zinaDMSO (dimethyl sulfoxide), dichloromethane,ndiTHF (tetrahydrofuran), zomwe zingasokoneze kukhulupirika kwadongosolo pakapita nthawi.
Ntchito Zapadziko Lonse za PEEK Tubing
Ma laboratories ambiri ndi mafakitale amadalira machubu a PEEK pazinthu zosiyanasiyana za HPLC. Mwachitsanzo, malo opangira mankhwala amagwiritsa ntchito machubu a PEEK kuti atsimikizire kulekanitsa kolondola komanso kolondola kwa mankhwala pakupanga mankhwala. Momwemonso, malo oyesera zachilengedwe amagwiritsa ntchito chubu la PEEK posanthula zitsanzo zamadzi ndi nthaka popanda kuyika pachiwopsezo choyipitsidwa ndi chubu lokha.
Sinthani Makina Anu a HPLC ndi PEEK Tubing
PEEK chubu ndiyofunika kukhala nayo kwa labotale iliyonse yomwe imachita bwino kwambiri madzimadzi chromatography. Ndi kukana kwake kwamphamvu kwambiri, kukana kwamphamvu kwamankhwala, komanso kukhazikika kwamafuta, machubu a PEEK amawonetsetsa kuti makina anu a HPLC amapereka zolondola komanso zodalirika. Maxi Scientific Instruments amapereka1/16" PEEK chubumu makulidwe osiyanasiyana ndi kulolerana kolondola kuti zigwirizane ndi ntchito zosiyanasiyana, zomwe zimapangitsa kukhala chisankho chosankhidwa m'ma laboratories padziko lonse lapansi.
Lumikizanani nafe lerokuti mudziwe zambiri za machubu athu apamwamba a PEEK ndi momwe angasinthire magwiridwe antchito komanso kulondola kwa kusanthula kwanu kwa HPLC.
