Melemo ea ho sebelisa PFA Solvent Tubing
1. Khanyetso ea Lik'hemik'hale: E 'ngoe ea mabaka a ka sehloohong a etsang hore PFA e rarolle li-tubing e ratoa ho chromatography ea metsi ke khanyetso ea eona e ikhethang ho lihlapolli tse mabifi le lik'hemik'hale tse senyang. Ho fapana le lisebelisoa tse ling, li-tubing tsa PFA li ke ke tsa nyenyefatsa ha li pepesetsoa lik'hemik'hale tse bohale, ho netefatsa hore sistimi ea hau e lula e tsitsitse mme liphetho tsa hau li lula li tsitsitse.
2. Li-extractable tse tlase: Ha o sebetsa ka chromatography ea metsi, sepheo ke ho qoba ho kenya litšila ka har'a lisampole tsa hau. Li-tubing tsa PFA li entsoe ka li-extractable tse tlase, ho bolelang hore li ke ke tsa kenya litšila ka har'a metsoako, ho boloka bohloeki ba litlhahlobo tsa hau.
3. Botsitso bo Phahameng ba Mocheso: PFA solvent tubing e ka mamella mefuta e mengata ea mocheso, e etsa hore e tšoanelehe bakeng sa li-solvents tse chesang le tse batang. Ho tsitsisa hona ha thempereichara ho netefatsa hore sistimi ea hau ea chromatography e sebetsa hantle maemong a fapaneng a ts'ebetso, ntle le ho senya ts'epahalo ea lihlahisoa kapa li-tubing ka botsona.
4. Ho tšoarella le ho Fetolana: PFA tubing e tsebahala ka ho tšoarella ha eona le ho tenyetseha ha eona. E hanana le ho petsoha, ho pshatleha, kapa kinking, leha e le maemong a feteletseng.

Mokhoa oa ho Khetha Tubing e nepahetseng ea PFA Solvent bakeng sa Litlhoko tsa Hao
Le ha PFA solvent tubing e le khetho e tšepahalang bakeng sa lits'ebetso tse ngata tsa mokelikeli oa chromatography, ho khetha mofuta o nepahetseng ho bohlokoa ho fihlela ts'ebetso e nepahetseng. Mona ke lintlha tse ling tseo u ka li nahanang ha u khetha tubing e nepahetseng:
•Boholo le Bolelele: Etsa bonnete ba hore bophara ba tubing le bolelele ba eona li lumellana le litlhoko tsa sistimi ea hau ea mokelikeli oa chromatography. Ho se lumellane ka boholo ho ka lebisa mathateng a kang khatello ea khatello, ho se lumellane ha sekhahla sa phallo, esita le ho hlōleha ha tsamaiso.
•Mocheso Range: Netefatsa hore tubing e khona ho sebetsana le ho feto-fetoha ha mocheso ho chromatography ea hau. Sena se tla thusa ho boloka ts'ebetso e tsitsitseng, ho sa tsotelehe litlhoko tsa kopo ea hau.
•Ho lumellana ha Lik'hemik'hale: Le hoja PFA e hanyetsana haholo le lihlapolli tse ngata, kamehla netefatsa hore e lumellana le metsoako e khethehileng eo u e sebelisang ts'ebetsong ea hau ea mokelikeli oa chromatography.
Likopo tsa PFA Solvent Tubing ho Liquid Chromatography
PFA solvent tubing e sebelisoa haholo lits'ebetsong tse fapaneng tsa chromatography, ho kenyelletsa:
•High-Performance Liquid Chromatography (HPLC): Li-tubing tsa PFA li atisa ho sebelisoa mekhoeng ea HPLC ho tsamaisa metsoako ntle le kotsi ea tšilafalo. Khanyetso ea eona ea lik'hemik'hale e tiisa hore e khona ho sebetsana le mekhahlelo e mabifi ea mehala e sebelisoang ho HPLC ntle le ho senya ts'ebetso ea sistimi.
•Ultra-High-Pressure Liquid Chromatography (UHPLC): Bakeng sa litsamaiso tse sebetsang ka likhatello tse phahameng haholo, li-tubing tsa solvent tsa PFA li fana ka nako e telele le ho feto-fetoha ha maemo ho hlokahalang ho boloka litekanyetso tse tsitsitseng tsa phallo le ho thibela ho lutla.
•Pokello ea Mehlala le Lipalangoang: Li-tubing tsa PFA hangata li sebelisoa bakeng sa sepalangoang se sireletsehileng sa lisampole tse hlokolosi, haholo ha bohloeki le thibelo ea tšilafalo e le bohlokoa.
Mehopolo ea ho Qetela: PFA Solvent Tubing le Bohlokoa ba eona ho Chromatography
Ho khetha li-tubing tse nepahetseng bakeng sa sistimi ea hau ea mokelikeli oa chromatography ho bohlokoa ho boloka liphetho tse nepahetseng, tse tšepahalang.
