Yini aisihlungi sesirinji

Isihlungi sesirinji siyithuluzi lesihlungi elisheshayo, elikahle, nelithembekile elisetshenziswa njalo kumalabhorethri.Inobukeka obuhle, isisindo esincane, nokuhlanzeka okuphezulu.Isetshenziselwa ikakhulukazi ukuhlunga isampula, ukucaciswa nokususwa kwezinhlayiya, kanye nokuhlunga koketshezi negesi inzalo.Kuyindlela ekhethwayo yokuhlunga amasampula amancane e-HPLC ne-GC.Ngokwendlela yokuvala inzalo, ingahlukaniswa ibe ukuvala inzalo nokungavala inzalo.
Isihlungi sesirinji asidingi ukushintsha ulwelwesi futhi sihlanze isihlungi, sisuse umsebenzi wokulungiselela oyinkimbinkimbi futhi odla isikhathi, futhi sisetshenziswa kakhulu elabhorethri.Umkhiqizo usetshenziselwa ikakhulukazi isampula yokucaciswa kwangaphambili, ukususwa kwezinhlayiyana, ukuhlunga inzalo, njll. Phakathi kwazo, isihlungi senaliti sisetshenziswa ngokuhambisana nesirinji elahlwayo.Kuyidivayisi esheshayo, elula nethembekile yokucubungula isampula yevolumu encane esetshenziswa njalo kumalabhorethri.Ububanzi baso bokuhlunga bungu-13mm no-30mm, futhi amandla okucubungula asuka ku-0.5ml kuya ku-200ml.
Izihlungi zezinaliti zasekhaya zihlukaniswa zibe izinhlelo ezilahlwayo nezisetshenziswa kaningi, eziphilayo noma zamanzi, ezinemininingwane ye-Φ13 noma Φ25, futhi zisetshenziselwa ukuhlunga isampula ekuhlaziyweni kwesigaba soketshezi noma segesi.Izinto zokuhlunga yilezi: inayiloni (Inayiloni), i-polyvinylidene fluoride (PVDF), i-polytetrafluoroethylene (PTFE), ixutshwe.

Kunganiisihlungi sesirinjiithandwa

Njengamanje, inethuba elihle lokuthuthuka emakethe futhi isetshenziswe kabanzi emakethe.Ihehe abathengi ukuthi bathenge.Imboni yesihlungi sesirinji iyimboni yemishini esezingeni eliphezulu futhi edidiyelwe kakhulu esetshenziswa ekuhlaziyeni i-chromatographic.Ukuhlunga kwesigaba esihambayo kanye nesampula kunomthelela omuhle ekuvikeleni ikholomu yechromatographic, isistimu yephampu yokufaka kanye nevalve yomjovo ekungcoleni.Isetshenziswa kabanzi ekuhlaziyweni kwe-gravimetric, i-microanalysis, ukuhlukaniswa kwe-colloid kanye nokuhlolwa kobunyumba.Kuyo yonke intuthuko phakathi neminyaka, ubuchwepheshe bokuhlunga isirinji yezwe lami buhlale buthuthukiswa futhi buthuthukiswa, futhi isabelo sabo emakethe yamazwe ngamazwe siyakhula, futhi sithandwa ngabathengi.

Yiziphi izizathu zokuthi kunganiizihlungi zesirinjibayathandwa?

1. Uphawu olucacisiwe olucacile luqeda inkinga yokudideka.Isihlungi sezindlu senziwe ngezinto ezisezingeni eliphezulu ze-sanitary polypropylene.

2. Isakhiwo somkhiqizo siklanywe ngokunembile ukuze kuqinisekiswe ukuhlunga okubushelelezi, ukuhlungwa kwesikhala sangaphakathi, kanye nezinga eliphansi kakhulu lensalela, ngaleyo ndlela kuncishiswe ukumoshakala kwamasampula.

3. Okunye okungalungile kwezihlungi zendabuko ukuthi kulula ukuziqhumisa.Lo mkhiqizo uklanyelwe ngokukhethekile ukumelana nokucindezela kokuqhuma okufika ku-7bar.

4. Ingxenye esemaphethelweni yesihlungi intambo, edlala umphumela ongasheleli, futhi idizayini eyenziwe ngumuntu yenza isisebenzisi sibe usizo.

5. Ikhwalithi ye-membrane ezinzile kanye nomehluko oyiziro phakathi kwamaqoqo kuqinisekisa ukuvumelana kwemiphumela yokuhlaziya.
