Isingeniso ku-Centrifugation kanye nezicelo zayo

I-Centrifugation iyindlela esetshenziswa kabanzi emikhakheni ehlukahlukene njenge-biology, i-chemistry, kanye nezokwelapha. Ihilela ukuhlukaniswa kwezinto ngokusekelwe ekujuleni kwazo noma izinga lokuthuthwa kwenhlabathi. Ama-Centrifuge, imishini enamandla ehlonyiswe nge-rotor ejikeleza ngesivinini esikhulu, asebenzisa amandla e-centrifugal ukusheshisa ukuthuthwa kwenhlabathi. Lesi sihloko sihlose ukuhlola ukusetshenziswa okuhlukahlukene kwe-centrifugation kanye nokubaluleka kwayo ocwaningweni lwesayensi kanye nezinqubo zezimboni.

Ukuhlola Isimiso Sokugqamisa I-Centrifugation

Isimiso se-centrifugation sijikeleza ekusebenzisaneni phakathi kwamandla e-centrifugal kanye nesilinganiso se-sedimentation. Lapho ingxube ifakwa ku-centrifuge futhi i-rotor iqala ukujikeleza, amandla e-centrifugal asetshenziswa ezinhlayiyeni ezikhona engxubeni abangela ukuba ziphume. Lokhu kuhamba kuholela ekuhlukanisweni kwezingxenye ezinobukhulu obuhlukene, njengoba izinhlayiya ezisindayo zishesha zibheke phansi kuyilapho izinhlayiya ezilula zakha izendlalelo ngaphezu kwazo.

Ukuhlukaniswa Kwezingxenye Zegazi kusetshenziswa i-Centrifugation

Enye yezindlela ezivame kakhulu zokusebenzisa i-centrifugation ekuhlukaniseni izingxenye zegazi. Uma igazi lonke lifakwa ku-centrifugation, lihlukaniswa libe yizingqimba ezintathu ezihlukene: i-plasma, i-buffy coat, namaseli abomvu egazi. I-plasma, ingxenye ewuketshezi yegazi, ihlala phezulu, kuyilapho amaseli abomvu egazi asindayo ehlala phansi. I-buffy coat, equkethe amaseli amhlophe egazi nama-platelet, yakha ungqimba oluncane phakathi kwe-plasma namaseli abomvu egazi. Lokhu kuhlukaniswa kuvumela ukuhlukaniswa nokuhlaziywa kwezingxenye ezithile zegazi ngezinjongo zokuxilonga noma ucwaningo lwezokwelapha.

Ukuhlanzwa Kwamaprotheni Nge-Ultracentrifugation

I-Ultracentrifugation, inqubo esebenzisa i-high speed centrifugation, ivame ukusetshenziswa ekuhlanzeni amaprotheni. Ngokufaka ingxube yeprotheni ku-ultracentrifugation, kungafinyelelwa izinyathelo eziningana zokuhlanza. Okokuqala, isinyathelo se-low speed centrifugation sisusa udoti noma ama-aggregates amakhulu eseli. Okulandelayo, i-high speed centrifugation ihlukanisa amaprotheni ancibilikayo ezingxenyeni ezingancibiliki. Ngaphezu kwalokho, i-density gradient ultracentrifugation ingasetshenziswa ukuhlukanisa amaprotheni athile ngokusekelwe ekubuthweni kwawo. Le nqubo yokuhlanza enembile ibalulekile ekusetshenzisweni okuhlukahlukene, okuhlanganisa ukucaciswa kwesakhiwo seprotheni, ukutholakala kwemithi, kanye nocwaningo lwezokwelapha.

Izicelo Zezimboni Zokukhuphula I-Centrifugation Ekucubungulweni Kwamakhemikhali

I-Centrifugation idlala indima ebalulekile ezimbonini zokucubungula amakhemikhali emisebenzini eyahlukene yokuhlukanisa. Isiza ekuhlukaniseni izinhlayiya eziqinile koketshezi, ukukhipha izingxenye ezibalulekile, kanye nokuhlanza imifudlana yenqubo. Isibonelo, ekukhiqizweni kwemithi, i-centrifugation isetshenziselwa ukususa ukungcola kanye nokuhlukanisa izinto eziqinile zekristalu koketshezi oluxubile. Embonini kawoyela negesi, i-centrifuge ihlukanisa kahle ama-emulsion kawoyela namanzi, okwenza kube lula ukubuyisa uwoyela futhi kuqinisekiswe ukuhambisana nemvelo. Ngaphezu kwalokho, ama-centrifuge asetshenziswa ezitshalweni zokwelashwa kwamanzi amdaka ukuze kususwe amanzi odaka kanye nasembonini yokudla ukuze kucaciswe amajusi, kuhlukaniswe amafutha, kanye nokucubungula ubisi.

Ekuphetheni, i-centrifugation iyindlela ehlukahlukene esetshenziselwa izinjongo zokuhlukanisa ezindaweni eziningi zesayensi nezimboni. Amandla ayo okuhlukanisa izinto ngokusekelwe esilinganisweni sokuthuthwa noma ubuningi avumela ukuhlukaniswa nokuhlanzwa kwezingxenye ezithile. Kusukela ekuhlukaniseni izingxenye zegazi kanye nokuhlanza amaprotheni ocwaningo kanye nezicelo zezokwelapha kuya ekwenzeni lula ukucubungula amakhemikhali kanye nokwelashwa kwamanzi amdaka, ama-centrifuge abe ngamathuluzi abalulekile emikhakheni eminingi. Ukuthuthukiswa okuqhubekayo kwamasu e-centrifugation ngokungangabazeki kuzoholela ekuthuthukisweni okuqhubekayo kanye nokusungula izinto ezintsha esikhathini esizayo.
