Ukuvula iimfihlo zokwahlulwa kweekhemikhali
Intshayelelo kwiCentrifuging njengeNdlela yoKwahlula iiKhemikhali
I-Centrifugation yindlela exabisekileyo esetyenziswa kakhulu kwiinkalo ezahlukeneyo zesayensi, ngakumbi kwikhemistri nakwi-biochemistry. Injongo yayo ephambili kukwahlula izinto ezinobunzima obahlukeneyo okanye izigaba ngokusebenzisa amandla e-centrifugal. Kodwa umbuzo usahleli: ngaba i-centrifuging yenza ukwahlulwa kweekhemikhali? Eli nqaku lijolise ekujongeni ubunzima be-centrifugation, liphonononge indlela esebenza ngayo, ukusetyenziswa kwayo, kunye nokusebenza kwayo njengendlela yokwahlula iikhemikhali.
Umgaqo Ophambili Wokwenza I-Centrifugation
Ukuze uqonde indlela i-centrifugation efikelela ngayo ekuhlukaniseni iikhemikhali, kubalulekile ukuqonda umgaqo wayo osisiseko. Le ndlela ixhomekeke ekusetyenzisweni kwamandla e-centrifugal, aveliswayo xa isampuli ijikeleziswa ngesantya esiphezulu. Izinto ezikwisampuli zifumana intsimi ye-centrifugal, nto leyo ebangela ukuba amasuntswana anoxinano olukhulu kwi-sediment ngokukhawuleza kunalawo anoxinano oluphantsi. Olu qhekeko lwenzeka ngenxa yokwahluka kwamazinga okuqhekeka kwe-sediment kwiinxalenye ezahlukeneyo kwisampuli.
Iintlobo zeendlela zeCentrifugation
I-Centrifugation inokwahlulwahlulwa ngokubanzi ibe ziindidi ezimbini: i-preparative kunye ne-analytical. I-Preparative centrifugation ijolise ekuhlukaniseni izinto ezininzi ukuze zisetyenziswe ngakumbi, ngelixa i-analytical centrifugation igxile ekuhlalutyeni iimpawu zee-particles kwisisombululo. Zombini ezi ndlela zisebenzisa iindlela ezahlukeneyo, ezifana ne-differential centrifugation, i-isopycnic centrifugation, kunye ne-velocity centrifugation, ukuze kufezekiswe ukwahlukana kweekhemikhali okusebenzayo.
Ukubeka iCentrifuging kwiindawo zoshishino
Ukucoca nge-centrifugation kudlala indima ebalulekileyo kwizicelo ezahlukeneyo zoshishino, ngakumbi kwimizi-mveliso yamayeza kunye neekhemikhali. Kwimveliso yamayeza, umzekelo, ukucoca nge-centrifugation kusetyenziswa ukwahlula ukungcola okuqinileyo kwizinto ezimanzi, ukuqinisekisa ubunyulu obuphezulu kunye nomgangatho wemveliso yokugqibela. Ngokufanayo, iinkqubo zeekhemikhali zihlala zifuna ukwahlulaniswa kweekhompawundi ezahlukeneyo, kwaye ukucoca nge-centrifugation kunika indlela esebenzayo yokwahlula izinto ezifunekayo.
I-Centrifugation kuPhando lwezoBomi
Intsimi ye-biomedical ixhomekeke kakhulu kwi-centrifugation ukuze yahlule izinto ezithile, ezifana neeproteni, i-DNA, kunye nee-organelles ezingaphantsi kweseli. Ngokusebenzisa amandla ahlukeneyo e-centrifugal kunye nee-reagents ezithile, abaphandi banokuhlula ngempumelelo ezi biomolecules kwimixube enzima. Le ndlela ibenza bakwazi ukufunda izinto ezizimeleyo, inegalelo ekuqhubekeni kwemimandla efana ne-genetics, i-proteomics, kunye ne-cellular biology.
Uhlalutyo lweCentrifugation kunye neNdalo
I-Centrifugation ikwasebenzisa uhlalutyo lokusingqongileyo. Umzekelo, izityalo zonyango lwamanzi amdaka zisebenzisa i-centrifuges ukwahlula inkunkuma eqinileyo emanzini, nto leyo enceda kwinkqubo yokucoca. Ngaphezu koko, i-centrifugation ivumela izazinzulu ukuba zihlalutye inkunkuma kunye nokungcola okukhoyo kwiisampuli zokusingqongileyo, nto leyo enika ulwazi olubalulekileyo malunga nempilo yendalo kunye namanqanaba okungcola.
Uphuculo kwiTekhnoloji yeCentrifugation
Uphuhliso lwanamhlanje luye lwaguqula icandelo le-centrifugation, lwazisa iimpawu ezintsha eziphucula ukusebenza kwayo kakuhle kunye nokuchaneka. Ii-centrifuge ezinesantya esiphezulu ezixhotyiswe ngolawulo oluntsonkothileyo zivumela ukulungiswa okuchanekileyo kwesantya sokujikeleza, okwenza kube lula ukwahlulahlula iikhemikhali ngcono. Ukongeza, uphuhliso lwee-ultracentrifuge luvumela abaphandi ukuba bahlukanise ii-nanoparticles kunye nee-macromolecules ngempumelelo ngakumbi.
Imingeni kunye nokulinganiselwa kwe-Centrifugation
Njengakwezinye iindlela zesayensi, i-centrifugation inemida yayo. Omnye umngeni obalulekileyo usekumiseleni amandla afanelekileyo e-centrifugal kunye nobude bexesha elifunekayo ukuze kwahlulwe ngokufanelekileyo. Ngaphezu koko, ii-biomolecules ezithile ezibuthathaka zinokuba sengozini yokonakala okanye ukubola ngexesha lenkqubo. Kubalulekile ukuba izazinzulu ziqonde le mida kwaye zilungelelanise iindlela zazo ngokufanelekileyo ukuqinisekisa iziphumo ezichanekileyo.
Amathemba exesha elizayo kunye notshintsho
Ukusasaza i-centrifugation kuyaqhubeka nokukhula ngokukhawuleza, uphando oluqhubekayo lugxile ekuphuculeni amandla ayo. Iindlela ezintsha, ezifana nokusasaza i-centrifugation esekelwe kwi-microfluidic, ziyaphuhliswa ukuze kujongwane nemida yeendlela zemveli.
