Kwihlabathi le-high-performance liquid chromatography (HPLC), ukukhetha i-tubing efanelekileyo kubalulekile ekufezekiseni iziphumo ezichanekileyo nezithembekileyo. Enye yezona zinto zidumileyo nezisebenzayo zikhoyoItyhubhu ye-PEEK, edlala indima ebalulekileyo ekuqinisekiseni ukuchaneka kohlalutyo lweekhemikhali phantsi koxinzelelo oluphezulu. Kweli nqaku, siza kuphonononga ukuba kutheni i-PEEK ityhubhu ilolona khetho luphezulu kwiingcali zaselabhoratri kunye nendlela ukukhetha ubungakanani obufanelekileyo kunye neenkcukacha ezinokuthi zinyuse imifuniselo yakho yolwelo lwechromatography.
Kutheni i-PEEK Tubing ibalulekile kwi-HPLC
I-High-Performance Liquid Chromatography (HPLC) bubuchule bokuhlalutya obuntsonkothileyo obusetyenziswa kakhulu kumashishini ahlukeneyo, kubandakanywa amayeza, ukubeka iliso kokusingqongileyo, kunye nokhuseleko lokutya. Ngexesha lohlalutyo lwe-HPLC, ii-reagents zimpontshwa kuxinzelelo oluphezulu ngenkqubo, ebeka uxinzelelo olukhulu kwi-tubing. Oku kwenza ukuba kube yimfuneko ukusebenzisa iityhubhu eyomeleleyo, ekwaziyo ukumelana neekhemikhali, kwaye ekwaziyo ukumelana namaqondo obushushu aphezulu.
I-PEEK tubing, inamandla omatshini abalaseleyo kunye nokumelana neekhemikhali, iyilelwe ukuhlangabezana nezi mfuno zinzima. Iyakwazi ukumelana noxinzelelo ukuya kuma-300ibha, iyenza ilungele ukusetyenziswa kwizicelo zeHPLC. Ngaphezu koko, i-PEEK (i-Polyetheretherketone) ayifuni i-ion zetsimbi, iqinisekisa ukuba uhlalutyo luhlala lukhululekile ekungcoleni, olubaluleke kakhulu kwiinkqubo zokuhlalutya apho ukuchaneka kuyo yonke into.
Iimpawu eziphambili ze-1/16 "PEEK Tubing
Izixhobo zeNzululwazi zeMaxi (Suzhou) Co., Ltd.inikeza1/16” i-PEEK tubhingkwiisayizi ezahlukeneyo, ikuvumela ukuba ukhethe iityhubhu ekufanelekela ukuseta iHPLC yakho. Idayamitha yangaphandle (OD) yetyhubhu yi-1/16” (1.58 mm), ubukhulu obuqhelekileyo obulingana neenkqubo ezininzi ze-HPLC. Ukhetho lwangaphakathi olukhoyo (ID) olukhoyo lubandakanya i-0.13mm, 0.18mm, 0.25mm, 0.5mm, 0.75mm, kunye ne-1mm, ikubonelela ngoluhlu olubanzi lweenketho kwiintlawulo ezahlukeneyo kunye nezicelo.
I-PEEK tubing evela kwi-Maxi Scientific Instruments iyaziwa ngokunyamezela kwayo± 0.001” (0.03mm)kuzo zombini iidayamitha zangaphakathi nangaphandle, ukuqinisekisa ukuhambelana ekusebenzeni. Oku kuchanekileyo kubalulekile kwiziphumo ezithembekileyo ze-HPLC, apho nokwahluka okuncinci kunokuchaphazela umgangatho wohlalutyo. Ukongeza, kwi-odolo ye-PEEK yokubhobhoza ngaphezulu5 yeemitha, afree tubing cutteribonelelwe, eyenza ukusika iityhubhu kubude obufunayo kube lula kwaye kuchanekile.
Izinto eziluncedo zokuSebenzisa i-PEEK Tubing kwi-HPLC
1. Ukumelana noxinzelelo oluphezulu: I-tubing ye-PEEK yenzelwe ngokukodwa ukumelana neendawo eziphakamileyo zoxinzelelo, okwenza ukuba iphelele kwizicelo ze-HPLC apho i-reagents iphonswa phantsi koxinzelelo olunzima. Igcina ingqibelelo yayo phantsi kwamanqanaba oxinzelelo ukuya kuthi ga400 ibha, ukuqinisekisa ukuhamba kakuhle kunye nokungaphazamiseki ngexesha lokuhlalutya kwakho.
2. Ukumelana nemichiza: Enye yezinto ezibalaseleyo ze-PEEK ityhubhu kukuxhathisa kwayo kweekhemikhali. Inokusingatha uluhlu olubanzi lwe-solvents, kubandakanywa i-acids, iziseko, kunye ne-solvents ye-organic, ngaphandle kokuthotywa okanye ukukhupha ukungcola okuyingozi kwinkqubo. Oku kuyenza ilungele uhlalutyo lweekhemikhali ezibuthathaka ezifuna ubunyulu kunye nokuchaneka.
3. Ukuzinza kweThermal: I-PEEK tubing ikwaqhayisa ngokuchukumisayoindawo yokunyibilika yama-350°C, okwenza ukuba ixhathise ukushisa okuphezulu okunokuthi kwenzeke ngexesha lokuhlalutya ixesha elide okanye lobushushu obuphezulu. Oku kuxhathisa ubushushu kuqinisekisa ukuba ityhubhu ihlala isebenza nakwimimandla yobushushu obuphezulu, ibonelela ngokuthembeka kwiimeko ezahlukeneyo zovavanyo.
4. Ukuhambelana neFinger-Tight Fittings: I-PEEK tubing yenzelwe ukusebenza ngokungenamthungo kunye nezixhobo eziqinileyo zomnwe, ukubonelela uxhulumaniso olulula kunye olusebenzayo ngaphandle kwesidingo sezixhobo ezinzima. Olu phawu lusebenziseka lula lwenza kube lula ukuseta nokugcina inkqubo yakho ye-HPLC.
5. Umbala-Ikhowudi yokuchongwa ngokulula: I-tubing ye-PEEK inemibala esekelwe kwi-diameter yangaphakathi (ID) ukunceda ukuchongwa lula. Ngelixa i-inki inokuguga ngokusetyenziswa, ayichaphazeli ukusebenza kwetyhubhu, ukuqinisekisa ukuba usenokuxhomekeka kuyo kuhlalutyo lwakho.
Yintoni omele uyiphephe xa usebenzisa i-PEEK Tubing
Ngelixa i-PEEK i-tubing ixhathisa kakhulu kuluhlu olubanzi lweekhemikhali, kukho ezinye iimeko.I-asidi ye-sulfuric egxininisiweyokwayei-nitric acid egxininisiweyoinokonakalisa i-tubing, ngoko kufuneka igwenywe. Ukongeza, i-PEEK ityhubhu inokwanda xa ityhilwe kwizinyibilikisi ezithile ezifanaI-DMSO (i-dimethyl sulfoxide), idichloromethane, kwayeTHF (tetrahydrofuran), enokuchaphazela ingqibelelo yenkqubo ekuhambeni kwexesha.
Usetyenziso lweLizwe lokwenyani lwe-PEEK Tubing
Iilabhoratri ezininzi kunye namashishini axhomekeke kwityhubhu ye-PEEK kwiintlobo ngeentlobo zezicelo ze-HPLC. Ngokomzekelo, iilabhoratri zoxubo mayeza zisebenzisa i-PEEK ityhubhu ukuqinisekisa ukwahlula okuchanekileyo kunye nokuchanekileyo kweekhompawundi kuqulunqo lwamachiza. Ngokufanayo, amaziko ovavanyo lokusingqongileyo asebenzisa i-PEEK ityhubhu ukuhlalutya iisampulu zamanzi kunye nomhlaba ngaphandle kokubeka umngcipheko wokusuleleka kwityhubhu ngokwayo.
Yandisa inkqubo yakho ye-HPLC nge-PEEK Tubing
I-PEEK ityhubhu iyimfuneko kuyo nayiphi na ilabhoratri eqhuba ulwelo olusebenza kakhulu lwechromatography. Ngokumelana noxinzelelo oluphezulu, ukuchasana kweekhemikhali okugqwesileyo, kunye nokuzinza kwe-thermal, i-PEEK tubing iqinisekisa ukuba inkqubo yakho ye-HPLC inika iziphumo ezichanekileyo nezithembekileyo.
