Ungayikhetha Kanjani I-HPLC VIAL Septa ye-soplent yakho
Izici okufanele zicatshangelwe lapho ukhetha i-HPLC VIAL Septa
1. Ukuvumelana Kwamakhemikhali
Into yokuqala okufanele uyicabangele ukuhambisana kwamakhemikhali kwezinto ze-septum ezinama-solvents ohlela ukuzisebenzisa. Izinto ezahlukahlukene zinokubekezelela okuhlukile kumakhemikhali:
I-PTFE (polytetrafluoroethylene): I-PTFE yaziwa ngokumelana kwayo okuhle kwamakhemikhali futhi ilungele inqwaba yezinhlanzi, kufaka phakathi amakhemikhali awonakalisayo. Imvamisa isetshenziswa ngokuhlanganiswa nezinye izinto.
I-Silicone: I-Silicone Septa iyavumelana nezimo futhi ingabhekwa kabusha ngemuva kokungena nge-wirege, ibenze balungele imijovo ephindaphindwayo. Kodwa-ke, kungenzeka zingahambelani nawo wonke ama-solvents.
I-Buyl Rubber: Lokhu okuqukethwe kunezakhiwo ezinhle zokubopha uphawu, kepha kunokumelana okulinganiselwe kwamakhemikhali kuqhathaniswa ne-PTFE.
I-PTFE \ Silicone Composite: Kuhlanganisa izinzuzo zazo zombili izinto zokwakha, ngokuhambisana okuhle kwamakhemikhali nokusetshenziswa kabusha.
2. Uhlobo lwe-solvent
Uhlobo lwe-solvent olusetshenzisiwe luzothonya nokukhethwa kwe-septum:
Izisombululo zamanzi: ama-solvents asuselwa emanzini, i-silicone noma i-ptfe \ silicone Septa zivame ukunconywa ngenxa yokuhambisana kwawo okuhle.
I-Organic Solvents: Ngezinhlelo ze-organic ezifana ne-methanol noma i-acetonitritrile, i-PTFE noma i-PTFE \ ama-silicone composites ancanyelwa ukumelana kwawo kwamakhemikhali.
Amakhemikhali awonakalisayo: Kumakhemikhali awonakalisayo awonakalisayo anjengama-acid aqinile noma izisekelo, i-PTFE imvamisa iyisinqumo esihle kakhulu.
3. Ukusebenza uphawu
Amandla we-Septum wokuphinda akopele ngemuva kokubhoboza inaliti kubalulekile ekugcineni ubuqotho besampula:
I-Slit vs Design Engelona-slit: Ezinye ze-SEPTA ziye zivimbela ukufakwa kwenaliti, kepha lokhu kungathinta uphawu ngokuhamba kwesikhathi. Imiklamo engeyona eye-slit inikezela nge-tighter seal kepha ingadinga amandla amaningi lapho ijova.
Ukusetshenziswa kabusha: Funa nge-Septa ekwazi ukuphindisela ngempumelelo ngemuva kwama-punsle ama-Pinali amaningi ukuvikela ukungcoliswa nokuhwamuka.
Ufuna ukwazi ukuthi ukhetha iSepta ku-Pre-Slit noma cha? Sicela ubheke le ndatshana: Ungayikhetha kanjani i-Septa Preta Pre-Slit noma cha?

Lapho usebenza ngamasampula abucayi, kubalulekile ukuthi ubheke ukukhishwa kwangaphandle kanye nokukhafulela ngezinto ezibonakalayo ze-Septum:
Ama-extractable aphansi: Khetha Septa nge-extractables ephansi ukunciphisa ubungozi bokungcola. I-PTFE inezinto ezikhishwe eziphansi uma ziqhathaniswa nezinto zokwakha ezisekelwa irabha.
Amazinga wokuhlola: Abanye abakhiqizi bahlinzeka ngemininingwane yokukhishwa; Buyekeza lezi zincwadi lapho ukhetha uSeptum.
I-5. Ukumelana okuphezulu okuphezulu
Cabanga ngobubanzi bokushisa lapho uhlelo lwakho lwe-HPLC luzosebenza khona:
Ukushisa okuphezulu: Uma uhlelo lwakho lokusebenza lubandakanya amazinga okushisa aphezulu, qiniseka ukuthi i-Septum Material ingamelana nalezi zimo ngaphandle kokonakaliswa.
Izicelo ze-Cryogenic: Okwezinhlelo zokusebenza ze-CryOgenic, khetha izinto ezigcina ubuqotho emazingeni okushisa aphansi.
6. Izakhiwo ezibonakalayo
Izici zomzimba ze-Secum zingathinta futhi ukusebenza:
Ubukhulu: I-Swer Septa inganikeza uphawu olungcono kodwa ingadinga amandla amaningi ngesikhathi sokungena kwenaliti.
Ubulukhuni: Izinto ezithambile zinganikeza ukuphelelwa okungcono kepha kungahle kube nokulimala ngokwengeziwe ngesikhathi sokuphindaphinda okuphindaphindiwe.
