Kwi-high-performance liquid chromatography (HPLC), amacandelo ambalwa abaluleke kakhulu-okanye abiza kakhulu-njengekholamu yechromatography. Kodwa ngaba ubusazi ukuba ngokhathalelo olufanelekileyo kunye nokuphatha, unokwandisa kakhuluubomi bekholamu yekhromatografikwaye uphucule ukusebenza kakuhle ngokupheleleyo kwelebhu yakho?
Esi sikhokelo siphonononga iingcebiso zogcino oluqinisekisiweyo kunye nobuchule obusebenzayo obunokukunceda ukukhusela utyalo-mali lwakho kwaye uqinisekise iziphumo zohlalutyo ezingaguqukiyo ekuhambeni kwexesha.
Khetha iSigaba esiLungileyo esiSewulayo ukusuka ekuqaleni
Uhambo oluya kwindeubomi bekholamu yekhromatografiiqala ngokukhetha smart isinyibilikisi. Isigaba seselula esingalunganga sinokonakalisa izinto zokupakisha ikholamu, ukunciphisa isisombululo, okanye kubangele umonakalo ongenakuguqulwa. Ngalo lonke ixesha uqinisekise i-pH, amandla e-ionic, kunye nohlobo lwe-solvent iyahambelana nekhemistry yakho yekholomu ethile.
Ukukhupha izinyibilikisi kunye nokuzihluza phambi kokusetyenziswa nako kungamanyathelo abalulekileyo. Ezi zilumkiso zilula zithintela i-particulate clogging kunye nokwakheka kwe-bubble yegesi, zombini ezo zinokubeka esichengeni ukusebenza kwekholamu.
Yongeza iTeknikhi yakho yokutofa
Into engena kwikholamu ibalulekile nje ngokuba ifika njani apho. Iisampulu ezigcwele kakhulu okanye ezo ziqulathe amasuntswana anganciphisa ngokukhawuleza ubomi obusebenzisekayo bekholamu. Sebenzisa iisampulu ezilungiselelwe kakuhle-ezihluzwe nge-0.22 okanye i-0.45 µm izihluzo-ukuthintela ukuvaleka kunye nokwakhiwa koxinzelelo.
Ukuba usebenza ngeematriki ezintsonkothileyo okanye ezimdaka, cinga ukusebenzisa ikholamu yokugada okanye isihluzo sangaphambili. Ezi zixhobo ezifikelelekayo zinokubamba ungcoliseko ngaphambi kokuba zifike kuluhlu lohlalutyo, zandisa kakhuluubomi bekholamu yekhromatografi.
Misela iNkqubo yokuCoca rhoqo
Njengaso nasiphi na isixhobo esichanekileyo, ikholamu yakho idinga ukucocwa rhoqo ukugcina ukusebenza okuphezulu. Isenzo esihle kukugungxula ikholamu emva kokusetyenziswa ngakunye nge-solvent ehambelanayo, ngakumbi xa utshintshela phakathi kweenkqubo ze-buffer okanye iintlobo zesampulu.
Ukucoca okunzulu ngamaxesha athile kunye nezinyibilikisi ezinamandla kunokususa i-debris eqokelelweyo kunye neekhompawundi ze-hydrophobic. Qinisekisa ukuba ulandela i-column-specific cleaning protocol protocol kwaye ugweme ukusebenzisa iikhemikhali ezinobundlobongela ezinokonakalisa isigaba sokumisa.
Yigcine kanye phakathi koMbaleko
Ugcino olululo luhlala lungahoywa, kodwa ludlala indima enkulu ekugcineni indawo yakhoubomi bekholamu yekhromatografi. Ukuba ikholamu ayiyi kusetyenziswa ixesha elide, kufuneka ihlanjululwe nge-solvent efanelekileyo yokugcina-ngokuqhelekileyo iqulethe i-organic component ukukhusela ukukhula kwe-microbial.
Soloko uvala zombini iziphelo ngokuqinileyo ukunqanda ukomisa okanye ukosuleleka. Ukugcinwa kwexesha elide, gcina ikholamu kwindawo ecocekileyo, elawulwa yiqondo lokushisa, kude nokukhanya okuthe ngqo kunye nokushisa.
Beka esweni ukusebenza kweKholam rhoqo
Ukugcina ilogi yoxinzelelo lwangasemva, ixesha lokugcina, kunye nokuma okuphezulu kunokukunceda ukuba uchonge iimpawu zokuqala zokuthotywa kwekholamu. Utshintsho olukhawulezileyo kwezi parameters lunokubonisa ungcoliseko, i-voids, okanye i-frit clogging.
Ngokubamba le miba kwangoko, unokwenza isenzo sokulungisa-njengokucoca okanye ukutshintshwa kwekholamu yokulinda-ngaphambi kokuba zichaphazele ngokusisigxina iziphumo zakho zohlalutyo.
Iingcamango Zokugqibela
Ukwandisa eyakhoubomi bekholamu yekhromatografiayikokugcina imali kuphela-imalunga nokugcina imfezeko yedatha, ukunciphisa ixesha lokuphumla, kunye nokuphucula imveliso yaselabhu. Ngesicwangciso esifanelekileyo sothintelo lolondolozo, unokukhusela enye yezona asethi zakho zelebhu zexabiso kwaye uqinisekise iziphumo ezithembeke ngakumbi kulo lonke uhambo.
Ngaba ufuna ingcebiso yeengcali kwiinkqubo zechromatographic okanye ukhetho lwemveliso?QhagamshelanaChromasirnamhlanje-silapha ukuze sixhase impumelelo yelabhu yakho ngengqiqo yobugcisa kunye nezisombululo ezenzelwe wena.
