Ukugcina ikholomu yakho ye-chromatography isesimweni esikahle akuwona nje umkhuba omuhle—kubalulekile ukuze uthole imiphumela enembile kanye nokusebenza kahle kwezindleko zesikhathi eside. Kungakhathaliseki ukuthi usebenza ekuhlaziyweni kwemithi, ukuphepha kokudla, noma ukuhlola indawo ezungezile, ukufunda indlela yokwelula impilo yekholomu yakho ye-chromatography kuzonciphisa isikhathi sokuphumula, kuthuthukise ukukhiqizwa kabusha, futhi kusize ukugcina ukusebenza okungaguquki.
Isitoreji Esifanelekile Senza Wonke Umehluko
Esinye sezici ezishaywe indiva kakhulu zokugcinwa kwekholomu isitoreji esifanele. Izimo ezingalungile zokugcina zingaholela ekukhuleni kwe-microbial, ukuhwamuka kwe-solvent, kanye nomonakalo ongenakulungiseka. Hlala ulandela imihlahlandlela yesitoreji efanele ngokusekelwe ohlotsheni lwekholomu ye-chromatography oyisebenzisayo. Isibonelo, lapho ugcina amakholomu esigaba esibuyiselwe isikhathi eside, shayela ngengxube equkethe okungenani u-50% we-organic solvent, futhi uvale zombili iziphetho ngokuqinile. Uma usebenzisa izigaba zeselula ezivikelwe, gwema ukuvumela isilondolozi some ngaphakathi kwekholomu, njengoba lokhu kungabangela ukuna kukasawoti nokuvinjwa.
Ukuvimbela Ukuvinjelwa Nokungcoliswa
Ukugwema ukungcola kungenye yezindlela eziphumelela kakhulu zokwelula impilo yekholomu. Ukuhlunga kwezigaba zamaselula namasampuli kubalulekile. Sebenzisa izihlungi ezingu-0.22 µm noma ezingu-0.45 µm ukuze ususe izinhlayiya ngaphambi komjovo. Ukwengeza, ukushintshwa okujwayelekile kwezigxivizo ezigugile, amasirinji, nezitsha zesampula kuqinisekisa ukuthi akukho lutho lwangaphandle olungena ohlelweni. Kumalabhorethri asebenzisa omatikuletsheni abayinkimbinkimbi noma angcolile, ikholomu yonogada ingasebenza njengomugqa wokuqala wokuzivikela ngokumelene namasampula ahlobene nokungcola—ukumunca ukungcola ngaphambi kokuba afinyelele ikholomu yokuhlaziya.
Ukuhlanza Nokuhlanza Okujwayelekile Akuxoxiswana
Uma ikholomu yakho ye-chromatography isetshenziswa njalo, ukuhlanza okujwayelekile kubalulekile. Ukuhlanza ngezikhathi ezithile kususa inhlanganisela eyinsalela engabangela umsindo oyisisekelo, ukuphakama kwezipoki, noma ukulahlekelwa ukulungiswa. Hlanza ikholomu ngesixazululi esihambisana nesigaba esihambayo kodwa esiqine ngokwanele ukugeza noma iyiphi into egciniwe. Kumakholomu esigaba esibuyiselwe emuva, ingxube yamanzi, i-methanol, noma i-acetonitrile isebenza kahle. Faka ishejuli yokuhlanza yamasonto onke esekelwe kubuningi kanye nohlobo lokuhlaziya olwenziwa ukuze kuvinjelwe ukunqwabelana nokuqinisekisa ukusebenza kahle okuphezulu.
Sebenzisa Izihlungi Zangaphambili Zekholomu Namakholomu Onogada
Ukufaka isihlungi sangaphambi kwekholomu noma ikholomu yonogada kuwutshalomali oluncane olunembuyiselo enkulu. Lezi zingxenye zithwebula ama-particle kanye nezinhlanganisela ezigcinwe ngokuqinile ngaphambi kokuthi zingene kukholamu yokuhlaziya eyinhloko. Abagcini nje ngokunweba impilo yekholomu yakho ye-chromatography kodwa futhi bayayivikela ekukhuphukeni kokucindezela okungazelelwe okubangelwa ukuvinjwa. Nakuba lezi zinsiza zidinga ukushintshwa ngezikhathi ezithile, zithengeka kakhulu kunokuthatha indawo yekholomu egcwele yokuhlaziya.
Amathiphu Okulungisa Abasebenzisi be-HPLC
Kubasebenzisi be-HPLC, ukunaka ingcindezi yesistimu namazinga okugeleza kunganikeza izimpawu zokuqala zokuwohloka kwekholomu. Ukwenyuka okungazelelwe kwengcindezi yangemuva ngokuvamile kubonisa ukuvaleka, kuyilapho izikhathi zokugcina ezikhukhulekayo zingase ziphakamise ukuvaleka okuncane noma ukuwohloka kwesigaba. Ukusebenzisa izilinganiso zokugeleza ezifanele nokugwema izinguquko zengcindezi enamandla kuzovikela ubuqotho bakho kokubili ukupakishwa kwekholomu kanye nesigaba sakho sokunganyakazi. Ngaphezu kwalokho, gwema ukuveza ikholomu kuzincibilikisi ezingahambelani noma izimo ze-pH ngaphandle kobubanzi obunconyiwe, njengoba lokhu kungabangela ukuwohloka ngokushesha.
Imicabango yokugcina
Ikholomu yakho ye-chromatography iyingxenye ebalulekile yesistimu yakho yokuhlaziya, futhi ngokunakekelwa okufanele, ingaletha izinkulungwane zemijovo yekhwalithi ephezulu. Kusukela ekugcinweni okufanele kuya ekuhlanzeni nasekuhlungelweni okusebenzayo, ukuthatha umcabango wokunakekela kuqala akugcini nje ngokugcina ikhwalithi yedatha yakho kodwa futhi kunciphisa izindleko zokuyishintsha.
Ingabe ufuna ukuthuthukisa ukuhamba komsebenzi kwelebhu yakho ye-chromatography? Thola izixazululo ezinokwethenjelwa kanye nesiqondiso sochwepheshe kuI-Chromasir-lapho ukunemba kuhlangabezana nokwethembeka. Masisize ukunweba impilo yezisetshenziswa zakho futhi siphakamise imiphumela yakho.
