Iziphumo zophando zipapashwa kwijenali uhlalutyo lwe-chemistry. Isimo esiphezulu se-Supectrometry yindlela yohlalutyo lweziyobisi ngokusekwe kumlinganiso ochanekileyo womlinganiso we-5 ye-Ioleres kunye nobunzulu bophawu olulandelayo kubo (ubungakanani bawo). Olu lwazi luvumela ukuba ubone ubunzima bemoyam yeontandathu, isakhiwo sabo, esincedayo sibonisa imirhumo, njengeeproteni, i-lipids, i-metabolites, iziqwengana zeziyobisi kunye nezinye izinto.
I-Mass Spectrometric i-Ijung (i-MCI) ikuvumela ukuba ufumane ulwazi ngokusasazwa kwendawo yemolekyuli kwizicubu, ukuqhuba uhlaziyo lwe-ion kwi-Molecules kwinqaku lemolekyuli kwindawo ephantsi kwesifundo (umzekelo, i-tumat).
Ingcaciso yedatha ye-MSI ngumsebenzi onzima. Ekuqaleni, kunyanzelekile ukuba ube nomfanekiso-ngqondweni wokusasazwa kwee-ion kumphezulu we-tistoff withi, oko kukuthi, ukwakha umfanekiso oqhelekileyo we-ion, ihambelana nombala wayo. Ukusukela kumawakawaka ee-Ion ngawo inqaku ngalinye kufuneka uye kwiinqobo nje ezintathu zamanani ekufuneka uhloniphe idatha ye-MSI njengokuhambelana nendawo enemibala emithathu elandelayo ngumphandi.
"Kubalulekile ukwandisa umxholo womfanekiso okwiphumo olunokubakho, kunyanzelekile ukuba uthathele ingqalelo amanqaku ombono womntu, ngakumbi, ukungabinamntu, kunye nemvakalelo eyahlukileyo yokutshintsha ukukhanya nakwi-chroma.
Kwaye, nangona ithiyori yokuqonda umbala kuvavanywa ixesha elide (ukusukela kwisiqingatha sokuqala senkulungwane yama-20), nakwiingcali zengcali azikho ngokubanzi zaza zazamkela ezinye iimodeli zemathematics, zichaza kakuhle zonke iipropathi ezaziwayo zombono womntu , "Umbhali wokuqala wesifundo, umfundi ophumelele iSkooltech Asstasia Sarychev ithi.
Abaphandi abavela embindini we-teknoloji yesayensi kunye nobunjineli bemisebenzi enoluhlu lwedatha enkulu (i-CDIS) kunye nelebhu ye-SPI ye-SPI, engaphantsi kweyona ndlela eyaziwayo ngaphambili, kodwa kwi ixesha elifanayo ngokusekwe kwimfundiso yembono yombala womntu.
Indlela entsha igcina imida kunye ne-gradiles xa kusetyenziswa iindawo ezikhethiweyo zokwakhiwa kwe-Ionic efanayo. Ngenxa yoku, umfanekiso onophuzuzo uguqulelwa ngokulula kunezinye iindlela ekucingeleni idatha ye-MSI. Indlela ivavanyiwe zombini kwimodeli kunye nedatha yovavanyo efunyenwe ngabaphandi yelebhu ye-spactrometry ye-spactrometry ye-biologiogy kunye ne-curothech.
