Intshayelelo:
I-Centrifugation yindlela esetyenziswa kakhulu yelabhoratri esebenzisa umgaqo we-sedimentation ukwahlula izinto ngokusekelwe kumahluko azo obuninzi. Xa kufikwa ekuhlukaniseni iintsimbi kwisisombululo, i-centrifugation iba sisixhobo esibalulekileyo. Eli nqaku liza kujonga iinkcukacha zendlela yokwahlula iintsimbi kusetyenziswa i-centrifuge ngempumelelo, ligxininisa amaqhinga ahlukeneyo kunye nezinto ekufuneka ziqwalaselwe.
I. Ukuqonda i-Centrifugation kunye neenzuzo zayo kwi-Metal Diparation
- Imigaqo esisiseko ye-centrifugation
- Iingenelo zokusebenzisa i-centrifuge yokwahlulahlula isinyithi
I-Centrifugation yinkqubo yokujikelezisa umxube ngesantya esiphezulu, nto leyo ebangela ukuba izinto zahlulwe ngokusekelwe kubuninzi bazo. Kwimeko yokwahlulwa kwesinyithi, le ndlela iluncedo kakhulu njengoko ivumela ukwahlulwa kwamasuntswana esinyithi kwisisombululo, esinokuqulatha ukungcola okwahlukeneyo okanye ezinye iisinyithi. Ngokusebenzisa umahluko kubuninzi phakathi kweesinyithi, i-centrifuge iba sisixhobo esisebenzayo ekufezekiseni ukwahlulwa okusebenzayo.
II. Ukulungiselela iSampuli kunye nokukhetha i-Centrifugal Force efanelekileyo
- Ukuqokelela isisombululo esinesinyithi
- Iindlela zokulungiselela iisampulu
- Ukuchonga amandla afanelekileyo e-centrifugal
Ekuqaleni, isisombululo esinesinyithi kufuneka siqokelelwe, ukuqinisekisa ukuba simele iintsimbi ezifunekayo zokwahlulahlula. Ngokuxhomekeke kumthombo wesampulu, iindlela ezahlukeneyo ezifana nokucoca, ukukhupha i-solvent, okanye ukugaywa kwe-asidi zingasetyenziswa ukufumana isisombululo esifanayo. Emva koko, ukumisela amandla aphakathi nendawo afanelekileyo kubalulekile ukuqinisekisa ukwahlukana okusebenzayo. Izinto ezinje ngobukhulu besuntswana, ubuninzi, kunye nesantya sokubuyisela esifunekayo zidlala indima ephambili ekukhetheni amandla aphakathi nendawo afanelekileyo.
III. Iimeko ezifanelekileyo zokususa i-Centrifugation zoKwahlulwa kwesinyithi
- Ulawulo lobushushu ngexesha lokucoca i-centrifugation
- Ukukhetha uhlobo oluchanekileyo lwe-rotor kunye netyhubhu
- Ubude be-Centrifugation kunye nokwenza ngcono isantya
Ukugcina ulawulo oluchanekileyo lobushushu ngexesha lokwahlulwa kwesinyithi kubalulekile, njengoko ukutshintsha kobushushu kunokuchaphazela ukusebenza kakuhle kokwahlulwa. Ukukhethwa kweentlobo ezifanelekileyo zerotor kunye neetyhubhu ngokusekelwe ekuhambelaneni nesisombululo sesinyithi kubalulekile ukuze kuthintelwe nayiphi na imiba yokusabela okanye ungcoliseko. Ngaphezu koko, ukufumana ixesha elifanelekileyo kunye nesantya sokucoca kubalulekile ukuze kufezekiswe ukusebenza kakuhle kokwahlulwa ngaphandle kokubeka emngciphekweni iinxalenye zesinyithi okanye ukulahlekelwa zizo naziphi na izinto ezixabisekileyo.
IV. Iindlela zokusebenzisa i-Post-Centrifugation: Ukuphucula ukuPhila kunye nokuPhuculwa koBumsulwa
- Ukuqokelela iipellets zesinyithi ezahlulweyo
- Ukuhlamba nokomisa ii-pellets zesinyithi eziqokelelweyo
- Ukuphucula ubunyulu ngokusebenzisa iindlela ezilandelayo
Nje ukuba inkqubo yokucoca i-centrifugation igqityiwe, ii-pellets zesinyithi ezahlulweyo kufuneka ziqokelelwe ngononophelo ukuze kuthintelwe ukungcoliswa okanye ukulahleka kwezinto. Ukuhlamba ii-pellets zesinyithi ukususa naluphi na ukungcola okushiyekileyo uze emva koko uzomise ngamanyathelo abalulekileyo ukuqinisekisa ukuba iintsimbi eziqokelelweyo zilungele ukuhlalutywa okanye ukusetyenziswa ngakumbi. Kwezinye iimeko, iindlela ezongezelelweyo ezifana nokuhla kwemvula, ukucocwa nge-electro, okanye ukukhupha i-solvent zingasetyenziswa ukuphucula ubunyulu beentsimbi ezahlulweyo ukuba kuyimfuneko.
V. Izinto eziqwalaselwayo kuKhuseleko kunye neMikhwa eBalaseleyo yoKwahlulwa kweNsimbi
- Ukuphatha izinto ezinobungozi kunye nenkunkuma enobuthi
- Ukugcinwa nokucocwa ngokufanelekileyo kwe-centrifuge
- Izixhobo zokuzikhusela zomntu kunye nezikhokelo zokhuseleko
Ukhuseleko kufuneka luhlale luyinto ephambili xa kusenziwa ukwahlula isinyithi kusetyenziswa i-centrifuge. Ukuphatha izinto ezinobungozi okanye inkunkuma enobungozi kufuna ukuthotyelwa ngokungqongqo kwemigaqo yokhuseleko, kuquka ukusetyenziswa kwezixhobo zokuzikhusela ezifanelekileyo. Ukugcinwa rhoqo kunye nokucoca i-centrifuge kubalulekile ukuze kusebenze ngokuthembekileyo nangokungenazimpazamo. Ukuziqhelanisa nezikhokelo zokhuseleko kunye neendlela ezilungileyo kuqinisekisa indawo yokusebenza ekhuselekileyo kwaye kunciphisa umngcipheko weengozi.
Isiphelo:
Ukucoca isinyithi yindlela enamandla xa kufikwa ekuhlukaniseni iintsimbi kwisisombululo. Ngokulandela ngononophelo amanyathelo achaziweyo kweli nqaku, abaphandi kunye nososayensi banokuzahlula ngokufanelekileyo iintsimbi, bafumane ubunyulu obuphezulu kunye namazinga angcono okubuyisela. Ukusetyenziswa kwamandla afanelekileyo e-centrifugal, iimeko ezifanelekileyo, kunye neendlela zokuhlaziya emva kokucoca kuphucula inkqubo yokwahlula, okuvumela uhlalutyo olongezelelweyo okanye ukusetyenziswa kweentsimbi ezizimeleyo. Nangona kunjalo, kubalulekile ukukhumbula ukuba ukhuseleko kufuneka luhlale lubekwe phambili ngexesha leenkqubo zokwahlula isinyithi, ukuqinisekisa indawo ekhuselekileyo kubo bonke ababandakanyekayo. Ngolwazi olufanelekileyo kunye namanyathelo okhuseleko, ukucoca isinyithi kuba sisixhobo esixabisekileyo kwicandelo lokwahlula isinyithi.
