I-High Prestic Liquid Chromatography (HPLC) iyindlela ebalulekile yokuhlaziya esetshenziswa ezindaweni zokuhlanza ezinkambu ezihlukene njengezemithi, amabala ezemvelo, nokuphepha kokudla. Ngaphakathi kwezwe le-HPLC, kunezigaba ezimbili eziphambili: I-Analytical HPLC kanye ne-HPLC elungiselelwe. Ngenkathi womabili la masu asebenzisa izimiso ezifanayo ukuze ahlukanise amakhompiyutha, asetshenziselwa izinhloso ezihlukile futhi anamapharamitha ahlukile wokusebenza. Le bhulogi izohlola umehluko phakathi kwe-HPLC yokuhlaziya neyokulungiselela, kufaka phakathi inhloso yazo, isilinganiso sokusebenza, imishini, kanye nezicelo.

Ukuqonda Hellitical HPLC

Ukuchazwa nenhloso

I-Analytical HPLC igxile ngokuhlukile ekuhlukaniseni nasekuhlonzeni amakhompiyutha kusampula. Umgomo oyinhloko ukuthola imininingwane efanelekile neyalinganiso mayelana nezakhi ezikhona kwingxube. I-Analytical HPLC ivame ukusetshenziselwa:

Ukuhlaziywa kwezimo: Ukuhlonza izakhi zesampula.

Ukuhlaziywa kwenani: Ukunquma ukugcwala kwe-compound ethile kwisampula.

Isikali sokusebenza

I-Analytical HPLC isebenza ngesilinganiso esincane, imvamisa ibandakanya imijovo yesampula ye-microliter. Amavolumu asetshenzisiwe ngokuvamile ebangeni le-1 kuye ku-100 μL, okuvumela amasampula amaningi ahlaziywe ngokugijima okukodwa. Lesi silinganiso esincane silungele ukuhlolwa okujwayelekile nokulawulwa kwekhwalithi.

Usayizi wekholomu nosayizi wezinhlayiyana

Amakholomu asetshenziswe ku-HPLCICAL HPLC ngokuvamile ambalwa ububanzi, ngokujwayelekile azungeze i-4.6 mm, futhi agcwele izinhlayiya zesigaba ezincane (3-5 μm). Lokhu kucushwa kuvumela ukulungiswa okuphezulu nokuhlukaniswa okusebenzayo kwe-Compound, elilungele ukuhlaziya okuningiliziwe.

Izindlela zokutholwa

I-Analytical HPLC isebenzisa izindlela ezahlukahlukene zokutholwa, kufaka phakathi i-UV-ebonakalayo, i-fluorescence, kanye ne-mass spectrometry. Ukukhethwa komtshina kuncike endalweni ye-analyte kanye nezidingo ezithile zokuhlaziywa. Ukuthola okungeyona eyonakalisayo kuvame ukusetshenziselwa ukuqinisekisa ukuthi isampula ingahlaziywa ngaphandle kokulahleka okukhulu.

Ukuqonda i-HPLC elungiselelweni

Ukuchazwa nenhloso

Ngakolunye uhlangothi i-HPLC, ngakolunye uhlangothi, ihlose ukuhlukanisa futhi ihlanze amakhompiyutha athile avela kwingxube. Umgomo oyinhloko ukuhlukanisa inani elanele le-tage compound ukuze kuhlaziywa khona noma kusetshenziswe. -Fanelekile

I-HPLC isetshenziselwa izicelo ezilandelayo:

Ukuhlukaniswa kwe-Compound: Ukukhishwa kanye nokuhlanzwa kwamakhompiyutha athile ocwaningo noma izinhlelo zezimboni.

Ukulungiswa kwesampula: Ukulungiselela amasampula ukuhlaziya okulandelayo.

Isilinganiso sokusebenza

I-HPLC elungiselelwe yenziwa ngesilinganiso esikhudlwana kune-HPLC ye-Analytical HPLC. Amavolumu wesampula angasukela kuma-milliliters ambalwa aze afike kumalitha amaningana, ngokuya ngesivuno esilindelekile se-complic eqondiwe. Lesi silinganiso esikhulu sivumela inani elanele lezinto ezihlanjululwe ukuze liqoqwe ukuze kusetshenziswe okunye.

Usayizi wekholomu nosayizi wezinhlayiyana

Amakholomu asetshenziselwa i-HPLC elungiselelwe ayikhudlwana kakhulu, ngokujwayelekile esukela ku-20 mm kuya ku-100 mm noma enkulu ububanzi. Amakholomu agcwele izinhlayiya zesigaba ezikhudlwana zokumisa (imvamisa 10-20 μm) ukwandisa amanani okugeleza futhi ahlangane amanani amakhulu wesampula. Lo mklamo usiza ukunciphisa ingcindezi emuva futhi uzuze ukuhlukaniswa okusebenzayo kwamakhompiyutha.

Izindlela zokutholwa

E-HOLLATION HOLC, izindlela zokutholwa zingahluka kulawo asetshenziswa ku-HPLC ehlaziya. Ngenkathi imishini yokuthola ezonakalisayo isajwayelekile, izinhlelo zokulungiselela zivame ukusebenzisa imishini yokuthola ezikwazi ukuqoqa izingxenyana ezisuselwa kuphrofayela yokuqedwa. Lokhu kuvumela amakhompiyutha athile ukuthi ahlukaniswe njengoba avela kwikholamu.

Ukukhetha phakathi kwe-HPLC yokuhlaziya neyokulungiselela

Lapho ukhetha phakathi kwe-HPLC yokuhlaziya neyokulungiselela, cabanga ngalezi zinto ezilandelayo:

Inhloso yokuhlaziywa: Thola ukuthi inhloso eyinhloko yini ukuhlaziya ama-compounds afanele futhi ngobuqili noma ukuhlukanisa amakhompiyutha athile ukuze kusetshenziswe okunye.

Inani lesampula: Hlola inani lesampula elikhona. Uma inani elincane lesampula liyatholakala, i-HPLC ehlaziya i-HPLC ingahle ilunge ngokwengeziwe. Ngakolunye uhlangothi, uma kudingeka inani elikhulu lesampula, i-HPLC elungiselelwe iyindlela engcono.

Ukuhlanzeka okudingayo nokuvunwa: cabanga ngobumsulwa obudingekayo kanye nesivuno se-comfered compound. I-PlyC elungiselelwe ukuthuthukisa ukululama kwe-compound ethile, ngenkathi ihlazo le-HPLC ligxile ekuhlinzekeni imininingwane eningiliziwe mayelana nokwakhiwa kwesampula.

Izinsizakusebenza kanye nemishini: Hlaziya izinsiza ezikhona, kufaka phakathi imishini nesabelomali. Izinhlelo zokulungiselela i-HPLC zivame ukubiza kakhulu futhi zidinga ukutshalwa kwezimali okuningi emishini yokusebenza nezindleko zokusebenza.

Ukugcina

Kokubili i-HPLC ehlaziya futhi elungiselelweni i-HPLC iyindlela ebalulekile emkhakheni we-chromatography, futhi ngayinye inokusetshenziswa okuhlukile ngokuya ngezidingo zabaphenyi kanye nezimboni. Ngenkathi ukuhlaziya i-HPLC ilungele ukuhlaziya okuningiliziwe kanye nokuncishiswa kwamakhompiyutha, i-HPLC elungiselelwe ibalulekile ekuhlukaniseni nasekuhlanzeni amakhompiyutha athile athile wokuthola ezinye izicelo. Ukuqonda umehluko phakathi kwalezi zinqubo ezimbili kuzosiza abacwaningi ukuba basebenzise izinqumo ezinolwazi, basebenzise ukuhamba kwabo emsebenzini, futhi bathole imiphumela efanelekile nethembekile ekuhlaziyweni kwabo. Njengoba ubuchwepheshe be-HPLC buqhubeka buqhubekisela phambili, zombili izindlela zokuhlaziya nezobulungiswa zizohlala ziyingxenye ebalulekile yocwaningo lwesayensi oluphumelelayo lwazo zonke izinhlobo.
