Melemo ea ho sebelisa PEEK Tubing ho HPLC
1. Ho hanyetsa Khatello e Phahameng: PEEK tubing e etselitsoe ka ho khetheha ho mamella maemo a khatello e phahameng, e etsa hore e be e loketseng bakeng sa lits'ebetso tsa HPLC moo li-reagents li pompeloang tlas'a khatello e feteletseng. E boloka botšepehi ba eona tlas'a maemo a khatello ea ho fihlela ho400 bar, ho etsa bonnete ba hore phallo e phallang hantle le e sa sitisoeng nakong ea tlhahlobo ea hau.
2. Khanyetso ea Lik'hemik'hale: E 'ngoe ea likarolo tse hlahelletseng tsa PEEK tubing ke khanyetso ea eona e ikhethang ea lik'hemik'hale. E ka sebetsana le mefuta e mengata ea li-solvents, ho kenyelletsa le li-acids, li-bases, le li-solvents, ntle le ho senya kapa ho kenya litšila tse kotsi tsamaisong. Sena se etsa hore e be se loketseng bakeng sa litlhahlobo tse hlokolosi tsa lik'hemik'hale tse hlokang bohloeki le ho nepahala.
3. Thermal Stability: PEEK tubing e boetse e ithorisa ka mokhoa o tsotehangsebaka se qhibilihang sa 350°C, ho etsa hore e be khahlanong le mocheso o phahameng o ka hlahang nakong ea tlhahlobo ea nako e telele kapa e phahameng ea mocheso. Ho hanyetsa mocheso ona ho tiisa hore tubing e lula e sebetsa esita le libakeng tse phahameng tsa mocheso, ho fana ka botšepehi ho pholletsa le maemo a fapaneng a liteko.
4. E lumellana le Finger-Tight Fittings: PEEK tubing e etselitsoe ho sebetsa ka mokhoa o tsitsitseng ka lisebelisoa tse tiileng tsa menoana, ho fana ka khokahanyo e bonolo le e sebetsang ntle le tlhokahalo ea lisebelisoa tse rarahaneng. Karolo ena e bonolo ho mosebedisi e etsa hore ho be bonolo ho theha le ho hlokomela sistimi ea hau ea HPLC.
5. Mebala-Khoutu bakeng sa Boitsebiso bo Bonolo: Tubing ea PEEK e na le mebala e thehiloeng ho bophara ba ka hare (ID) ho thusa ka boitsebiso bo bonolo. Le hoja enke e ka 'na ea senyeha ha e sebelisoa, ha e ame tshebetso ea tubing, ho etsa bonnete ba hore u ntse u ka itšetleha ka eona bakeng sa tlhahlobo ea hau.
Seo u lokelang ho se qoba ha u sebelisa PEEK Tubing
Le hoja li-tubing tsa PEEK li hanyetsana haholo le mefuta e mengata ea lik'hemik'hale, ho na le mekhelo e meng.E koahetse sulfuric acidleasiti ea nitric e matlae ka senya tubing, kahoo e lokela ho qojoa. Ho feta moo, li-tubing tsa PEEK li ka hola ha li pepesehetse lihlapolli tse ling joalo kaDMSO (dimethyl sulfoxide), dichloromethane, leTHF (tetrahydrofuran), e ka amang botšepehi ba tsamaiso ha nako e ntse e ea.
Lisebelisoa tsa 'Nete tsa Lefatše tsa PEEK Tubing
Lilaboratori le liindasteri tse ngata li itšetlehile ka li-tubing tsa PEEK bakeng sa mefuta e fapaneng ea likopo tsa HPLC. Mohlala, lilaboratori tsa meriana li sebelisa li-tubing tsa PEEK ho netefatsa karohano e nepahetseng le e nepahetseng ea metsoako mekhoeng ea lithethefatsi. Ka mokhoa o ts'oanang, lits'ebeletso tsa tlhahlobo ea tikoloho li sebelisa li-tubing tsa PEEK bakeng sa ho lekola lisampole tsa metsi le mobu ntle le ho beha kotsi ea tšilafalo e tsoang ho tubing ka boeona.
Ntlafatsa Sisteme ea hau ea HPLC ka PEEK Tubing
PEEK tubing ke ntho e lokelang ho ba teng bakeng sa laboratori efe kapa efe e etsang tšebetso e phahameng ea chromatography ea mokelikeli. Ka khanyetso ea eona e phahameng ea khatello, khanyetso e ntle ea lik'hemik'hale, le botsitso ba mocheso, PEEK tubing e netefatsa hore sistimi ea hau ea HPLC e fana ka liphetho tse nepahetseng le tse tšepahalang. Maxi Scientific Instruments e fana ka1/16" PEEK tubingka mefuta e fapaneng ea boholo le mamello e nepahetseng ho lumellana le lits'ebetso tse fapaneng, e leng se etsang hore e be khetho ea mantlha bakeng sa lilaboratori lefatšeng ka bophara.
Ikopanye le rona kajenoho ithuta haholoanyane ka li-tubing tsa rona tsa premium PEEK le kamoo e ka ntlafatsang katleho le ho nepahala ha litlhahlobo tsa hau tsa HPLC.
