Kukosha kwekuongorora kuperera kuyedzwa kwesirinji sefa

Kusefa kazhinji inhanho yakakosha mukushanda, saka kuyedzwa kwekuvimbika kwesirinji sefa kwakakosha, uye kukosha kwayo kuri mu:

1. Simbisa iyo chaiyo yekusefa pore saizi ye membrane

2. Tarisa kana sefa yakanyatsoputirwa

3. Kuonekwa kwekukuvara

4. Simbisa kuiswa kwakarurama

5. Simbisa kuti filtration system inowana verification performance

Kuvimbika kuyedzwa ndicho chigadzirwa chedu chitupa uye kugadzirwa kwemhando yekudzora, inova ndiyo yakajairwa maitiro ekushanda kwekambani

Chii chinonzi performance yesirinji sefa

Ipa sirinji yemuenzaniso sefa inoraswa inosanganisa cellulose membrane, naironi membrane, PVDF membrane ye polyvinylidene fluoride kuti isangane nezvinodiwa nevashandisi zvakasiyana zvekusefa vhoriyamu uye kuenderana kwemakemikari.

Iyo organic phase/organic sirinji sefa inotora PTFE (polytetrafluoroethylene) microporous membrane, ine yakanaka kuenderana kwemakemikari. Iyo ine yakanakisa makemikari kuramba kune general HPLC organic mhinduro senge methanol, acetonitrile, n-hexane, isopropanol, etc. Soluble. Inogona kushandiswa kusefa organic solvent samples.

Sefa ine aqueous/aqueous sirinji inoshandisa polyethersulfone (PES) microporous membrane. Inoshandiswa kusefa mvura-based solution samples, isina kukodzera kusefa organic solvent samples. Iyo sirinji sefa inoraswa inobvumira zvese zvine aqueous uye organic mhinduro kusefa nekukurumidza uye zvinobudirira.

Syringe sefa kuita: inokodzera mvura sisitimu uye akasiyana organic solvents, inopokana kune zvese zvinonyungudutsa, yakaderera solubility. Iine hunhu hwekupinda kwemhepo uye kusapinda kwemvura, mhepo yakakura inoyerera, yakakwirira particle retention rate, yakanaka tembiricha kuramba, kuramba kune yakasimba acids, alkalis, organic solvents uye oxidants, kuramba kuchembera, kusanamatira, kusapisa, kusa- toxicity, uye biocompatibility. Zvigadzirwa zvayo zvine hukama zvinoshandiswa zvakanyanya mumakemikari, mishonga, kuchengetedza kwezvakatipoteredza, zvemagetsi, chikafu, simba uye mamwe minda.

Chinangwa cheisirinji sefa

Iyo sirinji sefa inokurumidza, iri nyore uye yakavimbika sefa chishandiso chinogara chichishandiswa mumarabhoritari. Iine chimiro chakanaka, uremu huremu uye hutsanana hwepamusoro. Inonyanya kushandiswa semuenzaniso prefiltration, kujekesa uye kubvisa zvimedu, uye sterilization uye kusefa kwezvinwiwa uye magasi. Ndiyo nzira inosarudzika yekusefa diki sampuli dzeHPLC neGC. Zvinoenderana nemaitiro esterilization, inogona kupatsanurwa kuita sterillization uye isina-sterilization. Iyo inotevera mupepeti inokuzivisa iwe kune chinangwa chesirinji sefa:

1. Kubviswa kweprotein deposits uye kugadziriswa kwekugadzirisa

2. Chinwiwa uye kuongororwa kwekudya kwekuongorora uye kuongorora biofuel

3. Sample pretreatment

4. Kuongorora nekuongorora kwezvakatipoteredza

5. Kuongororwa kwemishonga uye zvigadzirwa zvepakutanga zvemvura

6. Liquid gas chromatography sampuli yekugadzirira uye chaiyo QC kuongororwa

7. Gasi kusefa uye kuona mvura
