Xa kuziwa ekufezekiseni iziphumo ezichanekileyo nezithembekileyoichromatography yolwelo, ukhetho lwamacandelo lungenza wonke umehluko. Enye into ebalulekileyo kodwa ehlala ingahoywa sisibane se-deuterium, esisebenza njengomthombo wokukhanya wezixhobo zokubona ezifana neDiode Array Detector (DAD) kunye neVariable Wavelength Detector (VWD). Ezi detectors zibalulekile ekuqinisekiseni ukwahlula okukumgangatho ophezulu, ukuchongwa, kunye nobungakanani kwiinkqubo zakho zohlalutyo. Kweli nqaku, siza kuphonononga ukubaluleka kwezibane zobomi obude be-deuterium kwi-liquid chromatography kunye nendlela abanokuphucula ngayo ukusebenza kakuhle, ukuthembeka, kunye nobomi obude bezixhobo zakho zohlalutyo.
Kutheni izibane zoBomi obude beDeuterium zibalulekile kwi-Liquid Chromatography
Izibane ze-Deuterium zisetyenziswa ngokubanzi kwiinkqubo ze-chromatography yolwelo ngokukwazi ukukhupha i-spectrum eqhubekayo yokukhanya, ezenza zilungele ukubonwa okubonakalayo kwe-UV. Ezi zibane zibalulekile ekuboneleleni ngomthombo wokukhanya ozinzileyo ofunekayo kumlinganiselo ochanekileyo wokufunxa isampulu kuwo wonke amaza ahlukeneyo. Nangona kunjalo, ubomi babo bunokuthintelwa zizinto ezifana nokusetyenziswa rhoqo kunye nokuvezwa kwimisinga ephezulu.
Izibane zexesha elide ze-deuterium, nangona kunjalo, zenzelwe ukubonelela ubomi benkonzo eyandisiweyo kunye nokusebenza okuhambelanayo, ukunciphisa isidingo sokutshintshwa rhoqo kunye nokunciphisa ixesha lokunciphisa kwiindawo zebhubhoratri. Ngokukhetha umgangatho ophezulu, isibane se-deuterium esihlala ixesha elide, abasebenzisi banokuqinisekisa ukusebenza kakuhle kwexesha elide, iindleko zokugcinwa okuphantsi, kunye neziphumo ezingcono.
Izibonelelo ze-Long-Life Deuterium Lamps kwi-DAD kunye ne-VWD Systems
1. Ukonyuka kokuSebenza kweSixhobo kunye nokuNcitshiswa kwexesha lokuphumla
Ubomi obude bezibane ze-deuterium buguqulela ngokuthe ngqo kwiindawo ezimbalwa zokutshintshwa kwezibane. Oku kuthetha ukuncitshiswa kwexesha lokuphumla, okwenza iilabhoratri zigcine imveliso kunye nokunciphisa iindleko ezinxulumene nokugcinwa kwezibane kunye nokutshintshwa. Ngesibane esihlala ixesha elide, inkqubo yakho yolwelo lwechromatography ihlala isebenza ixesha elide, iphucula ukusebenza kakuhle kokuhamba komsebenzi.
2. Umthombo wokukhanya ozinzileyo nothembekileyo
Izibane zobomi obude be-deuterium zibonelela ngokuphuma kokukhanya okuzinzileyo kwixesha elide. Oku kukhanya kungaguqukiyo kuqinisekisa ukuqokelelwa kwedatha ethembeke ngakumbi, okubalulekileyo ekuphindaphindeni kuhlalutyo lwechromatography. Ukukhanya okuzinzile kunceda ukunciphisa ukuguquguquka kwemilinganiselo enokuthi yenzeke ngezibane ezisezantsi okanye ezigugayo, okukhokelela kwiziphumo ezichanekileyo nezichanekileyo zokuhlalutya.
3. Iindleko-Ukusebenza
Ngelixa izibane zobomi obude be-deuterium zinokuba neendleko eziphezulu zokuqala, ixesha elide lokuphila kwabo kunokukhokelela ekongeni kweendleko ezinkulu ekuhambeni kwexesha. Ngokutshintshwa kwezibane ezimbalwa ezifunekayo kunye nokunciphisa ukuphazamiseka kokusebenza, ezi zibane zibonelela ngesisombululo sezoqoqosho kwixesha elide. Iilabhoratri zinokwaba uhlahlo lwabiwo-mali ngokunempumelelo ngakumbi, zityala imali kwamanye amacandelo abalulekileyo ngelixa bonwabele ukusebenza okungaguqukiyo kumthombo wazo wokukhanya.
4. Ukuchaneka okuPhuculo kwi-UV-Vis
Kwi-chromatography yolwelo, ubhaqo olubonakalayo lwe-UV lubalulekile ekuchongeni nasekulinganiseni amacandelo kwisampulu. Isibane se-deuterium esinika ubomi obude siqinisekisa ukuba ukuqina kwesibane kuhlala kungaguquguquki, nto leyo ibalulekile kwimilinganiselo echanekileyo. Ukukhutshwa kokukhanya okuhambelanayo kuqinisekisa ukuba i-detector ibamba ngokuchanekileyo i-absorbence, okwenza kube lula ukuchonga iikhompawundi zokuxilisa okuphantsi ngokuchaneka okuphezulu.
