Igesi i-Chromatography-Mass Spectrometry (GC-MS) isetshenziswa kabanzi ekuhlolweni kwezidakamizwa ngenxa yokuzwela okuphezulu, ukucaciswa, kanye nokwethenjwa ekutholeni izinto ezahlukahlukene. Nazi izizathu eziphambili zokuthi kungani i-GC-MS ibhekwa njenge- "Gold Standard" yokuhlola izidakamizwa:
Ukuzwela okuphezulu nokucaciswa
Ukutholwa kwamanani we-TRACE: I-GC-MS ingakhomba ukugxila okuphansi kakhulu kwezidakamizwa, ukuthola izinto njengomzuzu njenge-picograph e-picograph ku-utine Samples1. Leli zinga lokuzwela libalulekile ekuqinisekiseni ngokunembile izidakamizwa.
Ukukhonjwa okuqondile: Ubuchwepheshe bungahlukanisa phakathi kwezidakamizwa ezahlukahlukene kanye nama-metabolites abo, okuvumela ukukhonjwa okuqondile kwezinto ezingaba khona kuma-matric ayinkimbiko.
Ukuhlolwa kwezidakamizwa okuphelele
Uhla olubanzi lwezidakamizwa: I-GC-MS ingahle isikrini amakhulu ezidakamizwa ezahlukahlukene ngasikhathi sinye, okwenza kube lusizo kuzo zombili izindlela zokwelapha kanye nezidakamizwa zokuhlukunyezwa. Lesi sici siwusizo ikakhulukazi e-Clinical Foticology kanye nophenyo lwangaphambili.
Ukuhlolwa okuqinisekisiwe: Ngenkathi ukuhlolwa kokuqala kungasebenzisa izindlela ezingezinhle ezifana nama-immunoasans, i-GC-MS ivame ukusetshenziswa njengovivinyo oluqinisekisiwe ukuze uqinisekise imiphumela emihle kulezi zivivinyo zokuqala.
Ukuhambisana nokulawula
Izidingo ezijwayelekile: Izimboni eziningi, kufaka phakathi lezo ezilawulwa nguMnyango WezokuThutha (ichashaza), zidinga ukusetshenziswa kwe-GC-MS ukuqinisekisa imiphumela emihle evela kwizikrini zemithi yokuqala. Le mfuneko yokulawula igcizelela ukubaluleka kwayo ekuqinisekiseni imiphumela efanele yokuhlolwa kwezidakamizwa.
Ukulinganiselwa Kubhekwe
Nciphisa ama-Politives angamanga: Ukucaciswa kwe-GC-MS kunciphisa kakhulu ubungozi bezinto ezinhle kakhulu ezingenzeka kusetshenziswe izindlela ezinembile zokuhlola. Lokhu kuthembeka kubalulekile kuzilungiselelo zomthetho nakwezokwelashwa, lapho imiphumela efanele ibaluleke kakhulu.
Ukuzivumelanisa ngezimo eziguqukayo
Ngamafuphi, i-GC-MS ithandelwa ukuhlolwa kwezidakamizwa ngenxa yokuzwela kwayo okungenakuqhathaniswa nokucaciswa, amandla okuhlola okuphelele okuhlukahlukene kwezinto, ukuhambisana namazinga ahlukahlukene, kanye nekhono lokunciphisa ama-positives angamanga. Lezi zici zikwenza ithuluzi elibalulekile ezilungiselelweni zemitholampilo nakwama-forensic.
