Ekuhlaziyweni kwe-HPLC, ukunemba kwedatha kubalulekile. Ukukhetha umphakeli othembekile kubalulekile ukuthola imiphumela efanelekile yokuhlaziya. Kodwa-ke, kunabahlinzeki abaningi emakethe abangakhetha kuzo. Uyakwazi ukukhetha?
Kunezici ezinhlanu ezibalulekile ekutholeni umphakeli ofanele we-HPLC autosampler vials kanye nezinto zokudla.
Ikhwalithi Yomkhiqizo Nokuhambisana
Lonke ukhiye wenqubo ye-HPLC yempumelelo ukukhetha okulungileisampula vialkanye nensimbi. Zingafaniswa kahle. Ngakho-ke, udinga ukuthola umphakeli. Kumele banikele ngezinto ezahlukahlukene ze-vial kanye nosayizi. Lokhu kumele kuhlangabezane nezidingo zakho zokuhlola.
1. I-Vial Material
Isibonelo, ungadinga ingilazi. Noma, ungadinga ipulasitiki. Kuya ngamakhemikhali owahlaziya.
Amabhodlela engilazi ajwayelekile kakhulu. Banokungalingani okuhle kakhulu kanye nokumelana kwamakhemikhali. Kungomunye wokudla okusetshenziswa kakhulu ezindaweni zokucwaninga. Ingasetshenziswa emikhakheni ehlukahlukene.
Enye inketho ngamabhodlela epulasitiki enziweI-Polypropylenenoma i-polyethylene, okungukukhetha okungokomnotho okwengeziwe futhi okushibhile. Kuyinto yokukhetha amasampula abucayi be-PH, sodium noma ukuhlaziywa kwensimbi esindayo. Kepha ukuhambisana kwawo nama-solvents alonakalisayo noma amasampula angakhawulelwa.
2. Idizayini ye-vial
Idizayini ye-vial kufanele ihambisane ne-autosampler esetshenziswe kwithuluzi lakho le-HPLC. Ukucatshangelwa Kwemininingwane Esemqoka Kuhlanganisa:
a. I-Vial Shape nobukhulu - Kufanele ulingane kahle ku-autosampler tray.
b. Ukuqeda ngentamo (intambo yesikulufa, i-crimp,thamba) - Kufanele ihambisane nohlelo lokuvalwa.
c. Umthamo wevolumu - Qinisekisa ukuthi ivolumu ye-vial ilungele usayizi wakho wesampula.
d. Ukuba khona kwesichibi sokubhala noma indawo yokuhlonza isampula.
e. Eminye imiklamo ekhethekile ye-vial futhi ifaka izici ezifana nama-barcode, e-SEPTA, noma ifaka ukuthuthukisa ukuhambisana nokuhanjiswa.
3. Ukuhambelana okuyisamputhe
Hlaziya ngokucophelela ukuthi ngabe izinto ezibonakalayo nokuklanywa kuzohambisana ne-matrix yakho eyisampula. Izinto okufanele ucabangele:
a. Polarity kanye pH of analytes yakho
b. Ukuba khona kwama-solvents ezi-organic, ama-acid, noma izisekelo
c. Ukuthambekela kokuhlaziywa kwakho ku-adsorb ku-adderal ingilazi noma ezindaweni zepulasitiki
d. Kufanele uhlole ama-vials anama-matric ayisampula angempela. Lokhu kuzoqinisekisa ukuthi azikho izingqinamba ezinjenge-leaching, ama-adsorption, noma ukuhambisana.
Okuqukethwe kumele futhi kubekezelele izinga lokushisa le-HPLC yakho kanye nengcindezi. Kumele kwenziwe kanjalo ngaphandle kokonakalisa noma ukufuya. Bheka ukuthi imikhiqizo ihlolwe kahle. Bahlolwe ukuhambisana okuyisampula, ukuqina, kanye nokuqina kwesikhathi eside. Lokhu kuqinisekisa ukuthi ngeke bayekethise idatha yakho ngokungcola noma nge-adsorption.
KhethaHPLC VIALSOkwasampula akho kanye nensimbi yokuqinisekisa idatha ethembekile. Lokhu kukhetha ama-vials asekela ukuvela kabusha nobuqotho.
Umphakeli onolwazi anganikeza izeluleko zochwepheshe. Bangakusiza ukhethe ama-vials afanele ukusetshenziswa kwakho okuthile.
Ukuxhaswa okuphelele kwezobuchwepheshe
Umphakeli onolwazi kufanele anikeze ukusekelwa okuphelele kwezobuchwepheshe kwama-HPLC veials nezesekeli. Benza lokhu ukukusiza uthole kakhulu emikhiqizweni yabo. Lokhu kufaka ukuholwa ekukhetheni uhlobo oluhle kakhulu lwe-vial. Ibuye ibambezele ukubaluleka kokuhambisana kwesampula ye-Vial-Sampula. Futhi, ihlanganisa ukulungisa noma yiziphi izingqinamba ongahlangabezana nazo. Funa umphakeli ngezimpendulo zensizakalo ehlakaniphile, ephendulayo. Bangakwazi ukubhekana nemibuzo yakho nokukhathazeka kwakho ngokushesha. Benza lokhu ngocingo, nge-imeyili, noma ukuvakasha okuphakathi. Kufanele banikeze izeluleko zochwepheshe ngezinto. Lokhu kufaka phakathi ubukhulu be-vial, ukuvalwa kwezinhlelo nezici ezikhethekile. Iseluleko kufanele sihambisane nemishini yakho ethile ye-HPLC kanye nezidingo zohlelo lokusebenza.
Ukwethembeka Kwe-Supply Chain
Ukuhlaziywa kwe-HPLC kuvame ukudinga okutholakalayo. Lokhu kufaka phakathi ama-vials,iziqeshana, neSepta. Hlaziya ukuphathwa kokusungula komhlinzeki, izinqubo zokugcwalisa i-oda, kanye nokwethenjwa kokuhlinzekwa kwethempeli jikelele. Ingabe zinikeza imikhiqizo ngesikhathi ukuvimbela ukubambezeleka kokuhamba komsebenzi? Cabanga ngezinto. Lokhu kufaka phakathi izikhathi zokuhola. Futhi, ukunemba kwe-oda nekhono labo lokuphatha ama-rush noma ama-oda wangokwezifiso. Umphakeli omuhle uzoba nenethiwekhi eqinile yokusatshalaliswa. Bazoba nezinto eziguqukayo. Lokhu kuqinisekisa ukuthi uthola okudliwayo kwakho kwe-HPLC ngesikhathi, ngaso sonke isikhathi.
Ukulawulwa kwekhwalithi nokuhambisana nokulawula
I-HPLC ivamile kwizimboni ezilawulwayo. Lokhu kufaka phakathi amakhemisi, ukudla, kanye nokuhlolwa kwemvelo. Ubuqotho bedatha nokuhambisana kubalulekile kulezi zimboni. Qiniseka ukuthi umphakeli unezilawuli ezisezingeni eliphakeme. Lokhu kufaka isitifiketi se-ISO, ukuhlolwa okuningi kakhulu, kanye nemibhalo yokulawula. Lokhu kukunika ukuzethemba. Imikhiqizo yabo izohlangabezana nezinga eliqinile kanye namazinga alawulayo. Lokhu kuzovikela ubuqotho bemiphumela yakho yokuhlola. Funa abahlinzeki abanganikeza izitifiketi zokuhlaziywa. Kufanele futhi banikeze ukwesekwa kokuqinisekiswa kwendlela neminye imibhalo yokuqinisekisa ikhwalithi. Lokhu kuzokhombisa ukuzibophezela kwabo kwikhwalithi yomkhiqizo nokulandela umthetho.
Izinsizakalo ezingezwe nge-Value
Ikhwalithi yomkhiqizo kanye nokwethenjwa kubalulekile. Kepha, umphakeli omkhulu we-HPLC we-VPLC kanye nezesekeli kufanele futhi anikeze izinsizakalo ezingeziwe. Lezi zinsizakalo kufanele zithuthukise ukuhlaziywa kwakho. Funa abahlinzeki abangasenza ngokwezifiso imikhiqizo kwizidingo zakho. Kufanele banikeze umhlahlandlela wokuthuthukiswa kwesazi noma izinhlelo eziphelele zokulawulwa komthengisi. Lokhu okungeziwe kungahambisa ukuhamba kwakho komsebenzi. Bazophinde bakhuphule umkhiqizo. Bazothuthukisa ukubuyiselwa kwemali ekutshalweni kwemali kwakho kuzinto ze-HPLC. Isibonelo, abanye abahlinzeki bangenza osayizi be-vial ngokwezifiso. Bangakwenza futhi izintamo ezinkulu, ukuphrinta, noma ezinye izici. Lokhu kususelwa kwizidingo zakho. Abanye bangaba nososayensi besicelo sendlu. Bangasiza ngokwenza kahle kwendlela noma ukuxazulula inkinga.
Ngokuhlola lezi zinto ezibalulekile ezi-5, ungathola umphakeli. Bathengisa ama-vials we-HPLC autosampler nezesekeli. Bazoba ngumlingani weqiniso ekuhlinzekeni idatha ethembekile, esezingeni eliphakeme. Umhlinzeki othembekile uzohlinzeka ngemikhiqizo emihle. Bazophinde basekele impumelelo yelebhu yakho. Bazokwenza lokhu ngekhono. Banamaketanga okunikeza athembekile kanye nokwenza izinto ezintsha.
