Kunezinhlobo eziningi zokudla, okuthengwa isikhathi eside, nobunzima ekubhekeni ukuphepha. Ubuchwepheshe bokutholwa buyindlela ebalulekile yokuqinisekisa ukuphepha kokudla. Kodwa-ke, ubuchwepheshe obukhona bokutholwa bubhekana nezinselelo ekutholweni kokuphepha kokudla, okufana nokucaciswa okungalungile kwezinto ezisemqoka, isikhathi esiphansi sokwelashwa, kanye nokukhetha okuphansi kwezakhi ezibalulekile ze-Ion, okuholela ekuhlaziyeni kwangempela kwamasampula okudla. Lapho bebhekene nezinselelo, ithimba lethu lesazi esiphezulu eliholwa nguZhang Feng lithole uchungechunge lokuqhekeka kwezobuchwepheshe endaweni yokucwaninga yezinto ezisemqoka, izakhi eziyinhloko zokuhlolwa kokuphepha kokudla.
Mayelana nokucwaninga okubalulekile kwezinto ezibonakalayo kanye nentuthuko, iqembu lihlolile indlela ethile yokwelashwa kwama-adsorption yezinto zokwelashwa zangaphambi kokwelashwa ezintweni eziyingozi ekudleni, futhi yathuthukiswa uchungechunge lwezinhlelo ezithile ze-adsorption ezincane ze-adposincopt. Ukutholwa kwezinto eziqondiswe ku-Trace / Ultra Trace amazinga kudinga ukwelashwa kwangaphambi kokucebisa nokuhlanzwa, kepha izinto ezikhona zinamakhono okuvuthayo okulinganiselwe nokucaciswa okunganele, okuholela ekuboneni kokuthola izidingo zokuthola. Kusukela esakhiweni samangqamuzana, iqembu lihlaziye indlela ethize yokwelashwa kwama-adsorption kwezinto zokwelashwa kwangaphambi kokulashwa ekudleni, futhi zilungiselele uchungechunge lwezinto zokwakha amakhemikhali ezinomthethonqubo wamakhemikhali (FIRBO4 @ ama-nanoparticles. Isetshenziselwa ukucebisa nokuhlanjululwa kwezinto eziyingozi njenge-aflatoxins, izidakamizwa zezilwane ze-fluoroquinolone, kanye nesikhathi sokwelashwa kwangaphambi kokwelashwa kufinyeziwe kusuka emahoreni ambalwa kuya emizuzwini embalwa. Uma kuqhathaniswa nezindlela ezijwayelekile zikazwelonke, ukuzwela kokutholwa kukhuphuka izikhathi ezingaphezu kweziyikhulu, ukwephula ubunzima bezobuchwepheshe bezinto ezibonakalayo ezingezinhle zokucaciswa kwezinto ezibonakalayo eziholela ezinqubweni zokwelashwa ezibucayi kanye nokuzwela okuphansi, okunzima ukuhlangabezana nezidingo zokutholwa.
Ocwaningweni nasekuthuthukisweni kwezakhi eziyinhloko, iqembu lizohlukanisa izinto ezintsha futhi lizihlanganise ngemithombo eminingi ye-ion ion ukuthuthukisa izindlela zokutholwa ze-massrometry ezikhethiwe kakhulu. Njengamanje, imichilo yokuhlola yegolide evame ukusetshenziswa ye-colloidal yegolide yokuhlola okusheshayo ku-On-Site Add is inscane futhi iyaphatheka, kepha ukunemba kwawo kokuqina kanye nokunemba kwawo kuphansi. I-Mass Spectrometry inenzuzo yokunemba okuphezulu, kepha imishini inobuningi futhi idinga ukuncipha okusampula okude kanye nezinqubo zokwehlukaniswa kwe-chromatomagraphic, okwenza kube nzima ukuyisebenzisa ekutholweni okusheshayo kwesayithi. Iqembu liphuke ngebhodlela le-real-time spectrometry ion imithombo ye-ion kuphela enomsebenzi we-ionization kuphela, futhi wethule uchungechunge lwezobuchwepheshe bokuguqulwa kwezinto ezihlukanisayo emithonjeni eminingi ye-ion, enika amandla i-ion imithombo yokuhlukanisa umsebenzi. Kungahlanza imilobane eyisampula eyinkimbinkimbi efana nokudla ngenkathi i-ioring discrances displations, ukuqeda ukuhlukaniswa kwe-chromatome kwe-chromatome ngaphambi kokuhlaziywa kwe-chromatome ye-chromatome ngaphambi kokuhlaziywa kwe-post mass spectrometry, futhi kuthuthukiswe uchungechunge lwe-ukwahlukaniswa kwe-ionization ehlanganiswe real-time spectrometry ion imithombo. Uma impahla ethuthukisiwe ye-molecularly ebekiwe ihlanganiswa ne-substrate evuthayo ukuthuthukisa umthombo omusha we-mass spectrometry ion umthombo wokutholwa kokutholwa kwama-carbamate ama-esters ekudleni, isivinini sokutholwa se-audita afinyelela ku-0,5 μ ngokuqhathaniswa ne-0.5 kg Kuncishiswe kusuka kumashumi amaminithi kumashumi amasekhondi, futhi ukuzwela kuthuthukiswe cishe amahlandla angama-20, ukuxazulula inkinga yezobuchwepheshe ngokunemba okunganele kubuchwepheshe bokutholwa kokudla kokudla okuku-site.
Ngo-2023, iqembu lithole uchungechunge lokuphumelela kubuchwepheshe bokuhlola ukuphepha kokudla kokudla, ukuthuthukisa izihlazo ezintsha eziyi-8 nezinto zokucebisa kanye nezinto ezi-3 ezintsha ze-spectrometry ion Faka isicelo samalungelo obunikazi ayi-15; 14 Amalungelo obunikazi abagunyaziwe abagunyaziwe; Kutholwe ama-copyrights ama-2; Kuthuthukiswe amazinga okuphepha okudla okudla okungu-9 futhi kushicilelwe ama-athikili angama-21 kumajenali asekhaya nakwamanye amazwe, kufaka phakathi izindatshana eziyi-8 ze-SCI Zone 1.
