Ku-high-performance liquid chromatography (HPLC), izingxenye ezimbalwa zibaluleke kakhulu—noma zibiza kakhulu—njengekholomu ye-chromatography. Kodwa bewazi yini ukuthi ngokunakekelwa okufanele nokuphatha, unganweba kakhuluUbude besikhathi bekholomu ye-chromatographyfuthi uthuthukise ukusebenza kahle sekukonke kwelebhu yakho?
Lo mhlahlandlela uhlola amathiphu okunakekela afakazelwe kanye nezindlela ezisebenzayo ezingakusiza ukuvikela utshalomali lwakho futhi uqinisekise imiphumela engaguquki yokuhlaziya ngokuhamba kwesikhathi.
Khetha Isigaba Seselula Esilungile kusukela ekuqaleni
Uhambo oludeUbude besikhathi bekholomu ye-chromatographyiqala ngokukhetha i-solvent ehlakaniphile. Isigaba seselula esingalungile singehlisa isithunzi sokupakisha ikholomu, sinciphise ukulungiswa, noma sidale nomonakalo ongenakulungiseka. Njalo qinisekisa ukuthi i-pH, amandla e-ionic, nohlobo lwe-solvent kuyahambisana nekhemistri yekholomu yakho ethile.
Ukucwenga izincibilikisi nokuhlunga ngaphambi kokusetshenziswa nakho kuyizinyathelo ezibalulekile. Lezi zindlela zokuphepha ezilula zivimbela ukuvaleka kwezinhlayiya kanye nokwakheka kwebhamuza legesi, kokubili okungafaka engozini ukusebenza kwekholomu.
Lungiselela Isu Lakho Lomjovo
Okungena kukholamu kubaluleke kakhulu nokuthi kufika kanjani lapho. Amasampuli agcwele kakhulu noma lawo aqukethe ama-particle angafinyeza ngokushesha impilo esebenzisekayo yekholomu. Sebenzisa amasampuli alungiselelwe kahle—ahlungwe ngezihlungi ezingu-0.22 noma ezingu-0.45 µm—ukuvimbela ukuvinjwa nokwakheka kwengcindezi.
Uma usebenza ngomatikuletsheni abayinkimbinkimbi noma abangcolile, cabanga ukusebenzisa ikholomu yonogada noma isihlungi sangaphambi kwekholomu. Lezi zesekeli ezithengekayo zingabamba ukungcola ngaphambi kokuba zifinyelele kukholamu yokuhlaziya, zinwebe kakhuluUbude besikhathi bekholomu ye-chromatography.
Yakha Uhlelo Lokuhlanza Okuvamile
Njenganoma yimuphi ucezu lwesisetshenziswa esinembayo, ikholomu yakho idinga ukuhlanzwa okuvamile ukuze ulondoloze ukusebenza okuphezulu. Umkhuba omuhle uwukusula ikholomu ngemva kokusetshenziswa ngakunye ngesixazululi esihambisanayo, ikakhulukazi uma ushintsha phakathi kwesistimu yebhafa noma izinhlobo zesampula.
Ukuhlanza okujulile ngezikhathi ezithile ngezincibilikisi ezinamandla kungasusa izinsalela ezinqwabelene nezinhlanganisela ze-hydrophobic. Qiniseka ukuthi ulandela umthetho olandelwayo wokuhlanza oqondene nekholomu futhi ugweme ukusebenzisa amakhemikhali anolaka angase alimaze isigaba esimile.
Yigcine Kanye Phakathi Kwemigijimo
Isitoreji esifanele sivame ukunganakwa, nokho sidlala indima enkulu ekulondolozeni kwakhoUbude besikhathi bekholomu ye-chromatography. Uma ikholomu ingeke isetshenziswe isikhathi eside, kufanele igezwe ngesixazululi sesitoreji esifanele—ngokuvamile esiqukethe isakhi esiphilayo ukuze kuvinjelwe ukukhula kwamagciwane.
Njalo vala iziphetho zombili ngokuqinile ukuze ugweme ukomiswa noma ukungcoliswa. Ukuze uthole isitoreji sesikhathi eside, gcina ikholomu endaweni ehlanzekile, elawulwa izinga lokushisa, kude nokukhanya okuqondile nokushisa.
Qapha Ukusebenza Kwekholomu Njalo
Ukugcina ilogu yengcindezi yasemuva, isikhathi sokugcina, nokuma okuphezulu kungakusiza ukuthi ubone izimpawu zokuqala zokuwohloka kwekholomu. Izinguquko ezingazelelwe kulawa mapharamitha zingase zibonise ukungcola, i-voids, noma ukuvaleka kwe-frit.
Ngokuthola lezi zinkinga kusenesikhathi, ungathatha isinyathelo sokulungisa—njengokuhlanza noma ukushintsha ikholomu yonogada—ngaphambi kokuthi zithinte unomphela imiphumela yakho yokuhlaziya.
Imicabango yokugcina
Inweba eyakhoUbude besikhathi bekholomu ye-chromatographyakukhona nje ukonga imali—kumayelana nokugcina ubuqotho bedatha, ukunciphisa isikhathi sokuphumula, nokuthuthukisa ukukhiqiza ngelebhu. Ngesu elilungile lokuvikela lokuvikela, ungavikela enye yezimpahla zakho zelebhu ezibalulekile futhi uqinisekise imiphumela ethembeke kakhulu kukho konke ukusebenza.
