Ukuminyana, Izindlu Eziphothukile, Nokukhathala Kwesithupha: Indlela Yokukhetha Indlela Efanele Yokuhlunga Yezibonelo Ezinamandla Neziyinkimbinkimbi

Ukuvaleka, Amakhandlela Aphephukile, Nokukhathala Kwesithupha: Indlela Yokukhetha Indlela Yokuhlunga Efanele Yamasampula Ajiyile Nanzima
Ukuhlunga isampula ngaphambi kokuhlaziywa kwe-HPLC, UHPLC, noma i-LC-MS kubalulekile ukuze kuvikelwe amakholomu nezindlela zangaphakathi zensimbi ekuvinjelweni yizingqimba. Kodwa-ke, lapho usebenza nama-matrix ayinkimbinkimbi, ajiyile, noma anezinto eziningi eziqinile—njengamanzi angcolile emvelweni, izingcikitshi zenhlabathi, ama-fermentation broths, noma uketshezi lwezinto eziphilayo—ukulungiswa kwesampula okujwayelekile kuvamise ukuba yinkinga enkulu ekusebenzeni.
Uchwepheshe waselabhorethri ehlunga isampula lamanzi anamafutha ngomjovo wokuhlunga afaka esitsheni se-HPLC
Amalabhorethri avame ukuhlangabezana nalokhu:
  • Ukuvaleka okusheshayo kolwelwesi nokuvinjelwa ngemva kokucindezela ngaphansi kwe-0.5 mL yesampula.
  • Ukucindezela ngesandla ngokweqile okuholela ekuhlukanisekeni kwamagobolondo, ukugqabhuka kolwelwesi, nokulahleka kwamasampula.
  • Izindleko eziphezulu zokusebenza kanye nezikhathi ezinde zokulungiselela uma uzama ukufaka esikhundleni izihlungi ezijwayelekile zomjovo ngezinto zokuhlunga ezigxilile.
Ukuqonda indlela yokusebenza ngemuva kokuvinjelwa kwezinhlayiyana kuvumela amalabhorethri ukuba akhethe uhlelo lokuhlunga olonga izindleko nolusebenza kahle kakhulu.
  1. Kungani Izihlungi Ezijwayelekile Zomjovo Zehluleka Kumatrix Ayinkimbinkimbi
Izihlungi ezijwayelekile zomjovo zisebenzisa ulwelwesi olulodwa, oluyisicaba olunobukhulu obuthile bezimbotshana (ngokuvamile 0.22 µm noma 0.45 µm).
Uma isampula liqukethe ukusatshalaliswa okubanzi kosayizi wezinhlayiya—kusukela ezinhlayiyeni ezinkulu (>5 µm) kuya kuma-colloidal kanye nezinhlayiya ezingaphansi kwe-micron—okulandelayo kuyenzeka:
  • Ukwakheka Kwe-Cake Engaphezulu: Izinhlayiya ezinkulu zisheshe zimboze indawo evulekile ye-pore ye-membrane emathonsini ambalwa okuqala.
  • Ukukhuphuka Kwe-Hydraulic Pressure: Njengoba i-surface porosity yehla, umfutho wokujova owenziwa ngesandla uyanda ngokuphindwe kakhulu.
  • Ukwehluleka Kwesakhiwo: Abasebenzisi abacindezela ngamandla amakhulu bavame ukweqa umkhawulo wokugqekezeka kwengcindezi yezindlu ezijwayelekile ze-polypropylene (ngokuvamile amabha angu-5 kuya kwangu-7), okuholela ekuvuzeleni kwesampula noma ukuqhekeka kwendlu.
Ukuhlukaniswa kwesihlungi somjovo esivalekile nolwelwesi olunokwakheka kwekhekhe elingaphezulu kanye nokuqhuma kwekhasi
  1. Ukuhlola Ezinye Izindlela Zokuhlunga: Okuhle, Okubi, Nezindleko
Abaphathi belabhorethri ngokuvamile bacabangela izinketho ezintathu eziyinhloko lapho bebhekene nama-matrix angcolile:
Inketho A: Amashubhu Okuhlunga Asebenzisa I-Centrifugal Micro-Filter
  • Umgomo Wokusebenza: Amandla e-Centrifugal aqhuba uketshezi ngebhaskithi le-membrane elinemigodi emincane evundlile noma eme mpo.
  • Izinzuzo: Ukusebenza ngaphandle kwezandla; kuqeda ukukhathala kwesithupha; kulungele amasampula amancane kakhulu (< 500 µL).
  • Ububi: Izindleko eziphezulu zeyunithi (imvamisa izikhathi ezi-5 kuya kwezi-10 zenani le-filter ejwayelekile); izikhathi zokucubungula ezihamba kancane ezidinga imizuzu engu-10 kuya kwengu-30 ku-centrifuge; amakhekhe e-colloidal aminyene asavimba ukugeleza ngaphansi kwolwelwesi.
Inketho B: Izihlungi Zomjovo Ezinongqimba Olumbili / Izigaba Eziningi Nezihlungi Zangaphambi Kwe-Glass Fiber
  • Isimiso Sokusebenza: Isakhiwo esinezendlalelo eziningi esihlanganisa i-Glass Fiber (GF) yokuhlunga ejulile enezinga elihlelekile (usayizi we-pore 1.0 µm kuya ku-3.0 µm) ebekwe ngqo ngaphezulu kwe-membrane yokupolisha engaphansi kwe-micron (PTFE, PES, PVDF, noma i-Nylon).
  • Izinzuzo:
    • Ukusebenza Kokuhlunga Okujulile: I-pre-filter enemicu ibamba izinhlayiya ezinkulu kuyo yonke ubude bayo obunezilinganiso ezintathu, ivimbela ukuvaleka kwangaphambi kwesikhathi kwe-membrane yokugcina.
    • 3x to 5x Higher Throughput: Enables rapid filtration of 5 to 20 mL of difficult matrices with smooth, minimal thumb pressure.
    • Ukonga Izindleko: Kushibhile kakhulu kunezitsha ze-centrifuge kuyilapho kugcina ukuguquguquka okusheshayo, kwesampula elilodwa.
  • Ububi: Umthamo wokugcina amanzi uphezu kwe-ultra-micro centrifugal inserts (akulungele amasampula angaphansi kuka-200 µL).
Ukuhlukaniswa kwesihlungi somjovo esinezendlalelo ezimbili zefayibha yeglasi esihlungweni sangaphambi, okubonisa ukuhlunga okujulile kanye nolwelwesi lokugcina
Inketho C: Ama-96-Well Filter Plates Okusebenza Okuphezulu kanye nama-Vacuum / Positive Pressure Manifolds
  • Umgomo Wokusebenza: Ukucubungula amasampula angu-96 ngesikhathi esisodwa kusetshenziswa ama-microplates anama-filter membranes ashumekiwe, aqhutshwa i-vacuum noma umfutho womoya oqondile.
  • Izinzuzo: Ukuhlaziya okuphezulu kakhulu; kuqeda ngokuphelele ukuphathwa ngesandla; ukuhlanganiswa okungenazinkinga nama-automated liquid handlers.
  • Ububi: Kudinga imali yokuqala yokuthenga ama-manifolds noma ama-automated workstations; kufaneleka kakhulu amaqembu amasampula angu-48 noma ngaphezulu.
  1. Umhlahlandlela Wokukhetha I-Membrane Yezinto Ezinamafutha (Viscous Matrices)
Ukufanisa ikhemistri ye-membrane efanele ne-solvent yesampula yakho kubalulekile ukuvimbela ukubopha kwe-analyte kanye nokuvuvukala okubangelwa i-solvent:
  • Izixazululo Ezinamafutha Ezinamanzi & Eze-Biological (Amaprotheni, Ama-Enzyme, Ama-Broth):
    • Okunconyiwe: I-Glass Fiber Pre-filter + i-Polyethersulfone (PES) noma i-Regenerated Cellulose (RC).
    • Kungani: Ukumuncwa kwamaprotheni okungaqondile okuphansi kakhulu namazinga aphezulu okugeleza.
  • Izinto Ezikhiphayo Ezinamandla Eziphilayo & I-Chemical Matrix Ene-Viscous (Amafutha, Ama-Polymer Okwenziwa, Izikhishwa Zomhlabathi):
    • Recommended: Glass Fiber Pre-filter + Hydrophilic or Hydrophobic PTFE.
    • Kungani: Ukumelana namakhemikhali okubanzi kuwo wonke ama-solvents anamandla e-organic, ama-acid, nama-base.
  • Amanzi Ezimvelo Ajwayelekile & Ama-Solvents Axubile Angenamandla:
    • Okunconyiwe: Isihlungi sangaphambi kwe-Glass Fiber + Nylon (NY).
    • Kungani: Amandla aphezulu emishini, ukuhambisana okubanzi nezincibilikisi, nokumanzisa okuhle kakhulu.
  1. Izincomo Ezingokoqobo Zokuthuthukisa Ukulungiswa Kwamasampula
Ukuxazulula izinkinga zokuhlunga elabhorethri yakho:
  1. Yeka ukusebenzisa amafutha angqimba olulodwa angu-0.22/0.45 µm kumasampula angahluziwe, anamafu.
  2. Thuthukisa amasampula ayinselele avamile ukuze asebenzise amafutha e-Syringe Filter ane-Dual-Layer Glass Fiber Pre-filter (njenge-CHANCEPRO Dual-Layer GF+PTFE/PES/Nylon Series) ukuze kuqedwe ubunzima bokusikwa kwesithupha nokuqhuma kwezindlu.
  3. Kumasayizi amakhulu ebhashi (>100 amasampula ngosuku), shintsha kusuka kuma-syringe enziwa ngesandla uye kuma-96-Well Filtration Plates ahlanganiswe nama-vacuum manifolds (njenge-CHANCE INC High-Throughput Vacuum Extraction Systems) ukuze kuncishiswe kakhulu amahora omsebenzi wabasebenzi.
