Ukuthuthukisa ukusebenza kwelabhoratri nge-Peek tubing: umhlahlandlela ophelele

Esikhathini esingokoqobo se-chromatography ephezulu ye-chromatography (HPLC) namanye amasu wokuhlaziya, ukukhetha kweshubhu kungathinta kakhulu ukunemba nokwethenjwa kwemiphumela. I-Polythert Ether Ketone (Peek) tubing ivele njengento ethandwayo, enikeza inhlanganisela yamandla emishini kanye nokuphikiswa kwamakhemikhali. Le ndatshana idonsela ezinzuzo zeI-Peek tubing, ikakhulukazi "ububanzi obuhlukile obungu-1/4) obuhlukile, futhi uhlinzeka ngeziqondiso ekukhetheni ububanzi obufanele bengaphakathi (i-ID) yezinhlelo zokusebenza ezahlukahlukene.

Ukubaluleka kokukhethwa kweshubhu kuzicelo zokuhlaziya

Ukukhetha i-tubing efanele kubalulekile ekusethweni kokuhlaziya. Iqinisekisa:

•Ukufaneleka kwamakhemikhali: Kuvimbela ukusabela phakathi kwezinto ezifundwayo nama-sol noma amasampula.

•Ukumelana Nengcindezelo: Ibekezelela izingcindezi zokusebenza kohlelo ngaphandle kwe-deformation.

•Ukunemba okubucayi: Igcina amanani okugeleza aguqukayo futhi anciphise amavolumu afile.

Izinzuzo zeTheek Tubeng

I-Peek tubing ivelele ngenxa yayo:

•Amandla aphezulu wemishini: Iyakwazi ukubekezelela izingcindezi kuze kufike ku-400 bar, okwenza kube lula ukuthola izicelo eziphakeme kakhulu.

•Ukumelana Kwamakhemikhali: Inert to Solvents amaningi, ukunciphisa ubungozi bokungcoliswa kanye nokuqinisekisa ubuqotho bemiphumela yokuhlaziya.

•Ukuqina okushisayo: Ngephuzu lokuncibilika le-350 ° C, tubing tubing ihlala iqinile ngaphansi kwamazinga okushisa aphakeme.

•Biocomthation: Ilungele izinhlelo zokusebenza ezibandakanya amasampula endalo, ungaqiniseki ukuthi kungabikho okusebenzayo.

Ukuqonda 1/16 "I-OD Peek Tubeng

I-1/16 "i-OD ingusayizi ojwayelekile ezinhlelweni ze-HPLC, ezihambisana nokufakwa okuningi nezixhumi. Lokhu okujwayelekile kwenza lula ukuhlanganiswa kohlelo nokulungiswa. Ukukhethwa kobubanzi obungaphakathi (i-ID) kuyinto ebalulekile, ngoba ithonya amanani okugeleza kanye nengcindezi yohlelo.

Ukukhetha ububanzi obufanele bengaphakathi

I-Peek tubing iyatholakala kuma-ID ahlukahlukene, ukupheka ngakunye kwezidingo ezithile zokugeleza:

•I-0.13 mm (ebomvu): Ilungele izinhlelo zokusebenza eziphansi eziphansi lapho ukulawula okuqondile kubalulekile.

•I-0.18 mm (yemvelo): Ilungele amanani okugeleza alinganiselayo, ingcindezi yokulinganisa nokugeleza.

•I-0.25 mm (eluhlaza okwesibhakabhaka): Isetshenziswa kakhulu kuzinhlelo zokusebenza ezijwayelekile ze-HPLC.

•0.50 mm id (ophuzi): Isekela amanani aphezulu okugeleza, alungele i-chromatography elungiselelwe.

•I-0.75 mm (eluhlaza): Kusetshenziswe kuzinhlelo zokusebenza ezidinga ukugeleza okukhulu ngaphandle kokwakha ingcindezi.

•1.0 mm i-id (grey): Ilungele izinhlelo zokusebenza eziphakeme kakhulu zokugeleza, inciphisa i-backSsure.

Lapho ukhetha i-ID, cabanga ngokubonakala kwama-solvents akho, amanani wokugeleza ofiselekayo, kanye nemikhawulo yokucindezela kohlelo.

Imikhuba emihle kakhulu yokusebenzisa i-peek tubing

Ukwandisa izinzuzo ze-Peek tubing:

•Gwema izixazululo ezithile: I-Peek ayihambelani nama-sulfuric agxilile kanye nama-nitric acid. Ngokwengeziwe, ama-solvents afana ne-DMSO, i-DichloRomethane, kanye ne-thf kungadala ukunwetshwa kweshubhu. Qapha lapho usebenzisa lezi zinhlava.

•Amasu wokusika okufanele: Sebenzisa abasiki abafanelekile be-tubing ukuqinisekisa ukusikeka okuhlanzekile, okuhlanzekile, ukulondolozela uphawu olufanele nokugeleza kokugeleza okulungile.

•Ukuhlolwa njalo: Ngezikhathi ezithile hlola izimpawu zokugqoka, njengokuqhekeka komhlaba noma ukuguquguquka, ukuvikela ukwehluleka kohlelo olungaba khona.

Ukugcina

I-Peek tubing, ikakhulukazi i-1/16 "ehlukile, inikezela ngesisombululo esithembekile nesiguquguqukayo sohlelo lokusebenza oluhlukahlukene lokuhlaziya. Inhlanganisela yayo eyingqayizivele yamandla, ukumelana kwamakhemikhali, nokuqina okushisayo kwenza kube yingxenye ebalulekile kunoma yisiphi isimo selebhu. Ngokukhetha ububanzi obufanele bengaphakathi futhi banamathelisele emikhubeni engcono kakhulu, ama-laboratories angathuthukisa ukusebenza kwawo kokuhlaziya futhi aqinisekise imiphumela engaguquki, enembile.

Ngezixazululo ezisezingeni eliphakeme ze-tunetun tubing ezihambelana nezidingo zakho zelebhu, thintanaChromasirNamuhla. Ochwepheshe bethu bakulungele ukukusiza ekwakheni ukugeleza komsebenzi wakho wokuhlaziya.
