Ukuhlaziywa kwezemvelo okucasulayo yinkambu ebalulekile ehlose ukubheka nokuhlola ubukhona bokungcola emvelweni. Njengoba imisebenzi yabantu iba nomthelela omkhulu kwimvelo, sekubalulekile ukuqasha amasu wokuhlaziya athuthukile ukuze akhombe kahle futhi anciphise ukungcola. Phakathi kwamathuluzi abalulekile kuleli thuluzi lamathuluzi okuhlaziya, okudlalwa okuyisisekelo ekuqinisekiseni ubuqotho besampula ngaphambi kokuhlaziywa.

Le ndatshana idonsela endimeni ehlukahlukene yeIzihlungi zesirinjifuthi ifanela ukuthi zinikela kanjani ngokunemba nangokwethenjwa kokuhlaziywa kwezemvelo.

Ukuqonda Ukuhlaziywa Kwemvelo Ukuhlaziywa Kwezemvelo

Ukuhlaziywa kwemvelo okucasulayo kuhlanganisa uhla oluhlukahlukene lokungcola emoyeni, emanzini, inhlabathi kanye namasampula endalo. Lokhu kungcola, kufaka phakathi izinsimbi ezisindayo, ama-pesticides kanye nezinhlanganisela ezahlukahlukene ze-organic, kube yingozi enkulu kuyo yonke imvelo nasempilweni yabantu. Izindlela zokuhlaziya ezifana ne-chromatography kanye ne-spectroscopy ziqashwa ukuthola futhi zinciphise lezi zingcolisa ngezinga eliphakeme lokunemba.

Indima yokuhlunga kwesirinji:

Ukususwa kwezinhlayiya:

Udaba lokubandakanya amasampula ezemvelo lusuka emfucumfucu okhalweni nezinhlayiya ezinkulu ezingaphazamisa i-analyzer.Izihlungi zesirinjiNgamasayizi ahlukene we-Pore Pezes asebenza njengamaphilisi asebenzayo ukuze asuse izinhlayiya. Lokhu kuvimbela ukuvalwa kwamakholomu we-chromatographic, kuvikela izinto ezibucayi eziyithuluzi futhi kuqinisekise inqubo yokuhlaziya ebushelelezi.

Ihlatshwe umxhwele izihlungi ze-micron eziyi-0.45? Shona ngokujulile kwizicelo zabo nokubaluleka ngokubheka le ndatshana efundisayo:Igayidi ephelele yokuhlunga okungu-0.45 micron: konke okudingeka ukwazi

Ukuvikelwa kwezinsimbi zokuhlaziya:

Ukuzwela kwezinsimbi zokuhlaziya zanamuhla ezifana ne-HPLC ne-GC kudinga ukulungiswa kwesampula okucophelela. Umthetho Wezihlungi Oyisirinji njengomugqa wokuqala wokuvikela futhi uvikele lezi zinsimbi ekulimaleni okungenzeka okubangelwa ukungcola. Ukususwa kodaba lokubandakanya nokungcola kunwebisa impilo yamakholomu, ama-detators nezinye izinto ezibucayi, ukunciphisa isidingo sokulungiswa kanye nokulungiswa okubizayo.

Incazelo Yesampula:

Amasampula wezemvelo ajwayele ukufakwa kumatikuletsheni okuyinkimbinkimbi okuqukethe amakhompiyutha amaningi. Izihlungi zesirinji zifaka isandla ekucacisweni kwesampula ngokususa izingxenye ezingafuneki matrix. Le nqubo inyusa ukukhetha nokuzwela kwendlela yokuhlaziya. Lokhu kubaluleke kakhulu lapho ubhekene namazinga okulandela umkhondo lapho ukungqubuzana kungavimbela ukutholwa okunembile kanye nekani.

Imiphumela engaguquguquki futhi yezezimali:

Ukuthola imiphumela engaguquki futhi yezezimali kubaluleke kakhulu lapho kuhlaziya ukungcola kwemvelo. Izihlungi zesirinji ziqinisekisa ukuthi isampula ngayinye icutshungulwa ngokufana, iqeda ukuhlukahluka okungabeka engcupheni ukwethenjwa kwedatha. Ukuvumelana kokuhlelwa kwesampula okulungiselelwe yizihlungi zesirinji kunokwaba ukuqina kwendlela yokuhlaziya futhi kwenza abaphenyi bakwazi ukudweba iziphetho ezinembile nezinengqondo.

Iziphetho

Ekuphetheni,Izihlungi zesirinjibavele njengethuluzi elibalulekile ekuphishekeleni kokuhlaziywa okunembile nokuthembekile kwezemvelo. Indima yabo ehlukene ekususeni udaba lokuhlalisana, ukuvikela imishini yokuhlaziya, ukucacisa amasampula ayinkimbinkimbi kanye nokuqinisekisa ukuthi imiphumela engaguquki ibalulekile empumelelweni yezinhlelo zokuqapha imvelo. Njengoba ukukhathazeka kwemvelo kwezemvelo kuyaqhubeka, indima yokuhlunga okusirinji kuhlala kubalulekile ekugcineni ubuqotho bemvelo nokuvikela impilo yemvelo nezakhamuzi zayo.

Hlukana nomhlaba wezihlungi ze-micron eziyi-0,22. Vula ukubaluleka kwabo ezinhlelweni zokuhlunga ngokuhlola le ndaba efundisayo:Igayidi ephelele yokuhlunga okungu-0.22 micron: konke okudingeka ukwazi

Okwedlule:

Konke odinga ukukwazi mayelana nokuhlunga ngezimpawu zokucwaninga kwamaphrotheni
