Ensimini yokuhlaziywa kwelebhu, ikhwalithi yesampula nobuqotho kubaluleke kakhulu. Abaphenyi kanye nabahlaziyi bavame ukuhlangana namasampula anezimpawu eziyinselele ezifana nokuvuselela amakhemikhali aphezulu, ukuhlakanipha, kanye nodaba lokubandakanya. Ukubhekana nalezi zinselelo futhi uqinisekise imiphumela efanele, ukukhetha kwendlela yokuhlunga kubalulekile. Phakathi kwezinketho ezahlukahlukene zokuhlunga ezitholakalayo, i-PTFE (polytetrafluoroethylene) izihlungi zesirinji zivele njengesixazululo esithembekile futhi zinikele ngezinzuzo eziningi zokuphatha amasampula anzima.

Mayelana nokuhlunga kwesirinji oku-PTFE:

Izihlungi zesirinji (PTFE) Izihlungi zesirinjiBayingxenye yesigaba esibanzi sezihlungi ze-membrane ezisetshenziselwa ukulungiswa kwesampula ekuhlaziyeni kwelebhu. I-Fluoropolymer yokwenziwa, i-PTFE yaziwa ngokuvuselelwa kwayo kanye nokumelana namakhemikhali ahlukahlukene nama-sol. Lokhu kwenza izihlungi zesirinji ze-PTFE zilungele izinhlelo zokusebenza lapho ukuhambisana namasampula anolaka noma obunzima kubalulekile.

Ufuna ukwazi ukukhetha isihlungi esilungile sesirinji? Thola imininingwane ephelele kule ndatshana ukuthola izinqumo ezinolwazi: Ungasikhetha kanjani isihlungi esifanele sesirinji sokulungiswa kwesampula yakho?

Izinzuzo ezi-5 ezibalulekile zokuhlunga kwesirinji kwe-PTFE:

1. Ukufaneleka kwamakhemikhali:

Izihlungi zesirinji ze-PTfe zimelana namakhemikhali amaningi, kufaka phakathi ama-acid aqinile, izisekelo, kanye nezinto eziphilayo. Lokhu kuhlalisa okugcina kugcina impahla yokuhlunga ingasebenzi nge-matrix yesampula, ukuvikela ukusebenzisana okungathandeki nokungcola. Ngenxa yalokhu, abahlaziyi bangasebenzisa izihlungi zesirinji ze-PTFE ukuze balondoloze ubuqotho besampula ngesikhathi senqubo yokuhlunga futhi balondoloze ukunemba kwezilinganiso ezaphansi zokuhlaziya.

2. I-Hydrophobic:

I-hydrophobicicicicicity ye-PTFE yesirinji iyinzuzo enkulu lapho amasampula ecubungula aqukethe amanzi noma izisombululo zamanzi. Ngokungafani nezihlungi ze-hydrophilic, ezidonsa amanzi, izihlungi ze-PTFE ziphindaphinde izisombululo zamanzi amaningi futhi zilungiselela ukufombula kwezinto eziphilayo ze-organic kanye nezinhlanganisela ezingezona ze-polar. Le Hydrophobicity ayigcini nje ngokusiza inqubo yokuhlunga, kepha futhi inciphisa ubungozi bokugcinwa kwesampula ku-matrix yokuhlunga, busisa ukululama okuhlaziya kahle.

3. Ukumelana okuphezulu okuphezulu:

Izihlungi zesirinji ze-PTFE zingamelana namazinga okushisa aphezulu ngaphandle kokuyekethisa ubuqotho bezinhlekelele noma ukusebenza kahle kwe-filltration. Le mpahla iwusizo ikakhulukazi kuzinhlelo zokusebenza ezibandakanya amazinga okushisa aphezulu, njengokuhlaziywa kwezinhloso nezinqubo zokulungiswa kwesampula ezidinga ukwelashwa okushisa. Izihlungi zesirinji ze-PTFE zinikeza ukuguquguquka kanye nokwethenjwa kwezimo ezahlukahlukene zokuhlola ngokugcina ukuqina emazingeni okushisa aphakeme.

4. Okukhishwa okuphansi:

Okuqukethwe okukhishwe okuphansi kweIzihlungi zesirinji ze-PTFEKubalulekile ukuthi izinhlelo zokusebenza zokuhlaziya ezidinga ubumsulwa obuphezulu nokuphazanyiswa kwasemuva okuncane. Abakhiqizi basebenzisa izindlela zokulawula ikhwalithi eqinile ukunciphisa ubukhona bokukhishwa kwezihlungi ze-PTFE ukuze ukutakula amasampula kungabi nokungcola okutholakala ngaphandle. Lesi sici sibaluleke kakhulu kumasu wokuhlaziya abucayi lapho amanani okulandela umkhondo angathinta imiphumela. 5.

5. Ukuhambisana nokuhlunga okunyumba:

Izihlungi zesirinji ze-PTFE zitholakala ezinhlotsheni eziyinyumba zezinhlelo zokusebenza ezidinga ukulawulwa kwe-microbiological noma inzalo yesampula. Izihlungi ze-Ptfe eziyinyumba zisusa ngempumelelo ama-microorganisms kanye nezinkinga ezibandakanya izixazululo zamanzi futhi zinikeze ukuhlunga okulimayo kwamasampula endalo, amasiko, nezinye izinhlelo zokusebenza lapho kudalwa khona inzalo kubaluleke kakhulu.

Izicelo zokuhlunga ezi-6 ze-PTFE:

Ukuguquguquka okuhlukahlukene kwezihlungi zesirinji ze-PTFE zifinyelela ezinkundleni zesayensi ezahlukahlukene nasezindaweni zelebhu. Ezinye izinhlelo ezijwayelekile zifaka

Ukulungiswa kwesampula kwe-Chromatography: Izihlungi zesirinji ze-PTFE zisetshenziselwa kakhulu ukucacisa futhi amasampula we-degas ngaphambi kokuhlaziywa yi-HPLC, GC, LC-MS, namanye amasu.

Ukucaciswa kwamasampula we-viscous noma e-turbid: Izihlungi ze-PTFE zisebenza ekususeni udaba lokuhlanganisa nokungcola kusuka kumatikuletsheni olunzima lwesampula njengezixazululo ze-viscous noma ze-turbid.

Ukuhlunga kwezixazululo ezinolaka kanye ne-realents: izihlungi zesirinji ze-PTFE zingamelana nokuchayeka kumakhemikhali anolaka, ukuzenza zilungele ukuhlunga izixazululo eziqukethe ama-acid, izisekelo, noma izixazululo ze-organic.

Ukususwa okuhoxisiwe

Ukuhlunga okungunyumba: Izihlungi ze-Ptfe oyinyumba zibalulekile ekulawulweni kwe-microbial kanye nokufakwa kwezinye izinsimbi kuzinhlelo zokusebenza ezinjengesiko leseli kanye ne-microbiology.

Ekuphetheni,Izihlungi zesirinji ze-PTFENikeza uchungechunge lwezinzuzo ze-Laboratoration Filtration Izicelo, ikakhulukazi uma uphatha amasampula anzima wokuphatha. Ukumelana kwabo kwamakhemikhali, i-hydrophobicity, ukuqina kwezinga lokushisa, ukukhishwa okuphansi, kanye nokuhambisana nokuhlunga okuyinyumba kubenzele ithuluzi elibalulekile labaphenyi nabahlaziyi ezinhlobonhlobo zezindlela ezahlukahlukene zesayensi. Ngokufaka izinzuzo zokuhlunga kwesirinji kwe-PTFE, ama-laboratories angathuthukisa ukuthembeka, ukusebenza kahle, kanye nokunemba kokuhamba komsebenzi wabo wokuhlaziya, ekugcineni ukuthuthukisa ukucwaninga kwesayensi kanye nokwenza izinto ezintsha.
