Ezweni le-high-performance liquid chromatography (HPLC), ukukhetha ishubhu elifanele kubalulekile ukuze kuzuzwe imiphumela enembile, ethembekile. Enye yezinketho ezithandwa kakhulu nezisebenzayo ezitholakalayoIshubhu ye-PEEK, edlala indima ebalulekile ekuqinisekiseni ukunemba kokuhlaziywa kwamakhemikhali ngaphansi kwengcindezi ephezulu. Kulesi sihloko, sizohlola ukuthi kungani ishubhu ye-PEEK iyinketho ephezulu yochwepheshe baselabhorethri nokuthi ukukhetha usayizi ofanele kanye nokucaciswa kungakhuphula kanjani ukuhlolwa kwakho kwe-chromatography ewuketshezi.
Kungani i-PEEK Tubing Ibalulekile ku-HPLC
I-High-Performance Liquid Chromatography (HPLC) iyindlela yokuhlaziya esezingeni eliphezulu esetshenziswa kabanzi ezimbonini ezahlukahlukene, okuhlanganisa ezemithi, ukuqapha imvelo, nokuphepha kokudla. Ngesikhathi sokuhlaziywa kwe-HPLC, ama-reagents ampontshelwa ngengcindezi ephezulu ngohlelo, okubeka ingcindezi enkulu kushubhu. Lokhu kwenza kube semqoka ukusebenzisa amashubhu aqinile, amelana namakhemikhali, futhi akwazi ukumelana namazinga okushisa aphezulu.
Ishubhu le-PEEK, namandla ayo okusebenza amangalisayo nokumelana namakhemikhali, yakhelwe ukuhlangabezana nalezi zidingo ezidingekayo. Iyakwazi ukumelana nezingcindezi ezifika ku-300ibha, okuyenza ilungele ukusetshenziswa ezinhlelweni ze-HPLC. Ngaphezu kwalokho, i-PEEK (i-Polyetheretherketone) ayifaki i-ion yensimbi, iqinisekisa ukuthi ukuhlaziya kuhlala kukhululekile ekungcoleni, okubalulekile ezinqubweni zokuhlaziya lapho ukunemba kuyinto yonke.
Izici ezibalulekile ze-1/16” PEEK Tubing
I-Maxi Scientific Instruments (Suzhou) Co., Ltd.izipesheliIshubhu ye-PEEK engu-1/16”ngosayizi abahlukahlukene, okukuvumela ukuthi ukhethe ishubhu efanelana kangcono nokusetha kwakho kwe-HPLC. Ububanzi bangaphandle (OD) beshubhu bungu-1/16” (1.58 mm), usayizi ojwayelekile olingana nezinhlelo eziningi ze-HPLC. Izinketho ezitholakalayo zobubanzi bangaphakathi (ID) zifaka phakathi u-0.13mm, 0.18mm, 0.25mm, 0.5mm, 0.75mm, no-1mm, ikunikeza ngezinhlobonhlobo zezinketho zamazinga okugeleza ahlukene nezinhlelo zokusebenza.
I-PEEK tubing evela ku-Maxi Scientific Instruments yaziwa ngokubekezelela okuqinile± 0.001” (0.03mm)kukho kokubili amadayamitha angaphakathi nangaphandle, okuqinisekisa ukuvumelana ekusebenzeni. Lokhu kunemba kubalulekile emiphumeleni ethembekile ye-HPLC, lapho nokuhluka okuncane kungaba nomthelela kwikhwalithi yokuhlaziya. Ukwengeza, kuma-oda we-PEEK tubing over5 amamitha, ai-tubing cutter yamahhalainikezwa, okwenza ukusika ishubhu ubude obufunayo kube lula futhi kunembile.
Izinzuzo Zokusebenzisa I-PEEK Tubing ku-HPLC
1. Ukumelana Nokucindezela Okuphezulu: Ishubhu ye-PEEK yakhelwe ngokukhethekile ukumelana nezindawo ezinomfutho ophezulu, okuyenza ifanelekele izinhlelo zokusebenza ze-HPLC lapho ama-reagents ampontshwa ngaphansi kwengcindezi enkulu. Igcina ubuqotho bayo ngaphansi kwamazinga okucindezela okufika phezulu400 ibha, iqinisekisa ukugeleza okushelelayo nokungaphazamiseki phakathi nokuhlaziya kwakho.
2. Ukumelana Kwamakhemikhali: Esinye sezici ezivelele ze-PEEK tubing ukumelana kwayo namakhemikhali okuyingqayizivele. Ingakwazi ukusingatha izinhlobonhlobo zezincibilikisi, okuhlanganisa ama-asidi, izisekelo, nezincibilikisi eziphilayo, ngaphandle kokululaza noma ukukhiphela ukungcola okuyingozi ohlelweni. Lokhu kuyenza ilungele ukuhlaziya kwamakhemikhali okubucayi okudinga ubumsulwa nokunemba.
3. Ukuzinza Okushisayo: Ishubhu ye-PEEK nayo iyaziqhayisa ngokuhlaba umxhweleindawo yokuncibilika engu-350°C, okwenza imelane namazinga okushisa aphezulu okungenzeka ngesikhathi sokuhlaziya isikhathi eside noma izinga lokushisa eliphezulu. Lokhu kumelana nokushisa kuqinisekisa ukuthi amashubhu ahlala esebenza ngisho nasezindaweni ezinezinga lokushisa eliphezulu, okunikeza ukwethembeka kuzo zonke izimo zokuhlola ezihlukahlukene.
4. Ukuhambisana nokufakwa kweFinger-Tight: Ishubhu ye-PEEK iklanyelwe ukusebenza ngaphandle komthungo ngokufakwa okuqinile kweminwe, ihlinzeka ngoxhumano olulula nolusebenzayo ngaphandle kwesidingo samathuluzi ayinkimbinkimbi. Lesi sici esisebenziseka kalula senza kube lula ukusetha nokugcina isistimu yakho ye-HPLC.
5. Ifakwe Umbala Wokuhlonza Okulula: Ishubhu ye-PEEK inekhodi yombala ngokusekelwe kububanzi obungaphakathi (ID) ukuze isize ngokuhlonza kalula. Nakuba uyinki ingase iguge uma isetshenziswa, ayithinti ukusebenza kweshubhu, iqinisekisa ukuthi usengathembela kuyo ukuze uhlaziye.
Okufanele Ugweme Uma Usebenzisa I-PEEK Tubing
Ngenkathi ishubhu ye-PEEK imelana kakhulu nezinhlobonhlobo zamakhemikhali, kukhona okuhlukile.I-sulfuric acid egxililefuthii-nitric acid egxilileingalimaza i-tubing, ngakho-ke kufanele igwenywe. Ukwengeza, amashubhu e-PEEK angakhula lapho evezwe kumakhemikhali athile afana nalawaI-DMSO (i-dimethyl sulfoxide), i-dichloromethane, futhiI-THF (tetrahydrofuran), okungase kuthinte ubuqotho besistimu ngokuhamba kwesikhathi.
Izicelo Zomhlaba Wangempela ze-PEEK Tubing
Amalabhorethri amaningi nezimboni zithembele kushubhu we-PEEK ngezinhlelo zokusebenza ezihlukahlukene ze-HPLC. Isibonelo, amalabhorethri emithi asebenzisa amashubhu e-PEEK ukuze aqinisekise ukuhlukaniswa okunembile nokunembile kwezinhlanganisela ekwakhekeni kwezidakamizwa. Ngokufanayo, izikhungo zokuhlola imvelo zisebenzisa ishubhu le-PEEK ukuze zihlaziye amasampula amanzi nomhlabathi ngaphandle kokubeka engcupheni ukungcola okuvela kushubhu ngokwalo.
Lungiselela Isistimu Yakho ye-HPLC nge-PEEK Tubing
Ishubhu ye-PEEK iwufanele ube nayo kunoma iyiphi ilabhorethri eqhuba i-chromatography yoketshezi esebenza kahle kakhulu. Ngokumelana kwayo nokucindezela okuphezulu, ukumelana namakhemikhali okuhle kakhulu, nokuzinza kokushisa, ishubhu ye-PEEK iqinisekisa ukuthi uhlelo lwakho lwe-HPLC luletha imiphumela enembile nethembekile. I-Maxi Scientific Instruments inikezaIshubhu ye-PEEK engu-1/16”ngebanga losayizi nokubekezelelana okunembayo ukuze kuhambisane nezinhlelo zokusebenza ezihlukahlukene, okuyenza ibe yinketho yokuzikhethela kumalabhorethri emhlabeni wonke.
Xhumana nathi namuhlaukuze ufunde kabanzi mayelana neshubhu yethu ye-PEEK ye-premium nokuthi ingathuthukisa kanjani ukusebenza kahle nokunemba kokuhlaziywa kwakho kwe-HPLC.
