Sebakeng sa chromatography ea metsi e sebetsang hantle haholo (HPLC) le mekhoa e meng ea tlhahlobo, khetho ea li-tubing e ka ama ho nepahala le ho ts'epahala ha sephetho haholo. Polyether ether ketone (PEEK) tubing e hlahile e le thepa e ratoang, e fanang ka motsoako oa matla a mochine le khanyetso ea lik'hemik'hale. Sengoliloeng sena se hlahloba melemo eaPEEK tubing, haholo-holo 1/16” e fapaneng bophara ba bophara ba ka ntle (OD), 'me e fana ka tataiso mabapi le ho khetha bophara bo loketseng ba ka hare (ID) bakeng sa lits'ebetso tse fapaneng.
Bohlokoa ba Khetho ea Li-Tubing Lits'ebetsong tsa Analytical
Ho khetha li-tubing tse nepahetseng ho bohlokoa litlhophisong tsa tlhahlobo. E netefatsa:
•Ho lumellana ha Lik'hemik'hale: E thibela karabelo lipakeng tsa lisebelisoa tsa tubing le li-solvents kapa disampole.
•Ho Hanyetsa Khatello: E mamella likhatello tsa ts'ebetso ea tsamaiso ntle le deformation.
•Ho Nepaha ha Dimensional: E boloka litekanyetso tse tsitsitseng tsa phallo le ho fokotsa palo e shoeleng.
Melemo ea PEEK Tubing
PEEK tubing e ikhetha ka lebaka la:
•Matla a Phahameng a Mechini: E khona ho mamella likhatello ho fihlela ho 400 bar, e etsa hore e tšoanelehe bakeng sa likopo tse phahameng tsa khatello.
•Khanyetso ea Lik'hemik'hale: Ho kenella ho lihlapolli tse ngata, ho fokotsa kotsi ea tšilafalo le ho netefatsa botšepehi ba liphello tsa tlhahlobo.
•Thermal Stability: Ka ntlha ea ho qhibiliha ea 350 ° C, li-tubing tsa PEEK li lula li tsitsitse tlas'a mocheso o phahameng.
•Biocompatibility: E loketse lits'ebetso tse kenyelletsang lisampole tsa baeloji, ho netefatsa hore ha ho litšebelisano tse mpe.
Ho utloisisa 1/16” OD PEEK Tubing
1/16” OD ke boholo bo tloaelehileng mekhoeng ea HPLC, e tsamaellanang le li-fittings le lihokelo tse ngata.
Ho Khetha Diameter e nepahetseng ea ka hare
PEEK tubing e fumaneha ka li-ID tse fapaneng, e 'ngoe le e' ngoe e sebetsana le litlhoko tse khethehileng tsa phallo:
•0.13 mm ID (Khubelu): E loketse lits'ebetso tsa phallo e tlase moo taolo e nepahetseng e leng bohlokoa.
•0.18 mm ID (Tlhaho): E loketse litekanyetso tse itekanetseng tsa ho phalla, ho leka-lekanya khatello le ho phalla.
•0.25 mm ID (Boputsoa): E sebelisoa hangata lits'ebetsong tse tloaelehileng tsa HPLC.
•0.50 mm ID (Tšehla): E tšehetsa litekanyetso tse phahameng tsa phallo, tse loketseng chromatography e lokiselitsoeng.
•0.75 mm ID (Botala): E sebelisoa lits'ebetsong tse hlokang phallo e kholo ntle le khatello e matla ea khatello.
•1.0 mm ID (Bohlooho): E loketse bakeng sa lits'ebetso tse phallang haholo, ho fokotsa khatello ea morao.
Ha u khetha ID, nahana ka viscosity ea li-solvents tsa hau, litekanyetso tsa phallo tse lakatsehang, le meeli ea khatello ea sistimi.
Mekhoa e metle ea ho sebelisa PEEK Tubing
Ho eketsa melemo ea PEEK tubing:
•Qoba Litlhapi Tse itseng: PEEK ha e tsamaellane le acid e concentrated sulfuric le nitric acid. Ho feta moo, lihlapolli tse kang DMSO, dichloromethane, le THF li ka baka katoloso ea li-tubing. E-ba hlokolosi ha u sebelisa metsoako ena.
•Mekhoa e Loketseng ea ho Seha: Sebelisa li-tubing cutters tse loketseng ho etsa bonnete ba hore likhahla tse hloekileng, tse pota-potileng, ho boloka tiiso e nepahetseng le ho tsitsisa ha phallo.
•Tlhahlobo ea Kamehla: Nako le nako hlahloba matšoao a ho khathala, joalo ka mapetsong a bokaholimo kapa ho fifala, ho thibela ho hloleha ho ka bang teng ha sistimi.
Qetello
PEEK tubing, haholo-holo e fapaneng ea 1 / 16 "OD, e fana ka tharollo e ka tšeptjoang le e fapaneng bakeng sa lisebelisoa tse sa tšoaneng tsa tlhahlobo. Motsoako oa eona o ikhethang oa matla, lik'hemik'hale tsa lik'hemik'hale, le botsitso ba mocheso o etsa hore e be karolo ea bohlokoa sebakeng leha e le sefe sa laboratori.
Bakeng sa litharollo tsa boleng bo holimo tsa PEEK tse tsamaellanang le litlhoko tsa laboratori, ikopanyeChromasirkajeno. Litsebi tsa rona li ikemiselitse ho u thusa ho ntlafatsa ts'ebetso ea hau ea tlhahlobo.
