I-chromatography-mass spectrometry (GC-MS) isetyenziselwa ukuvavanywa kwezichizana ngenxa yokuziva unobuntu, obuthile, kunye nokuthembeka ekufumaneni uluhlu olubanzi lwezinto. Nazi izizathu eziphambili zokuba i-GC-Nks ithathwa njenge "imigangatho yegolide" yovavanyo lwamachiza:
Ubuntununtunu obuphezulu kunye nobunye
Ukufumanisa izixa-mali zeTrece: I-GC-MS inokuchonga ugxininiso olusezantsi lwamachiza, oluchongiweyo njengemizuzu eyi-1 yepipigram kwiisampulu ze-urine1. Eli nqanaba lemvakalelo lubalulekile ekusebenziseni ngokuchanekileyo iziyobisi.
Isazisi esithile: Itekhnoloji inokuthi iwahlula phakathi kwezinto ezibanzi zeziyobisi kunye neMetabolites zazo, zivumela ukuchongwa ngokuchanekileyo kwematriki enzima.
Uvavanyo olubanzi lweziyobisi
Uluhlu olubanzi lweziyobisi: I-GC-Nks inokukreqa kumakhulu amachiza ahlukeneyo, eyenza iluncedo kuzo zombini ezonyango kunye neziyobisi. Eli nqaku liluncedo ngokukhethekileyo kwiToologyOgy kunye nePolostric yoPhando.
Uvavanyo lokuqinisekisa: Ngelixa uvavanyo lokuqala lunokusebenzisa iindlela ezinobuchule ezifana ne-igoussossays, i-GC-MS ihlala isetyenziswa njengovavanyo oluqinisekisayo ukuqinisekisa iziphumo ezilungileyo.
Ukuthobela umthetho
Izinto ezifunekayo: Amashishini amaninzi, kubandakanywa nezo zilawulwa liSebe lezoThutho (i-DOT), funa ukusetyenziswa kwe-GC-MN ukungqina iziphumo ezilungileyo kwizikrini zokuqala. Le mfuno yomthetho igxininisa ukubaluleka kwayo ekuqinisekiseni iziphumo ezichanekileyo zovavanyo lweziyobisi.
Ukunqongophala okubhekelelweyo
Ukunciphisa i-POSTE PROSTERS: Ukuthintelwa kwe-GC-MS kunciphisa ingozi kubunyulu obungasenzeka kwi-postatives ebubuxoki enokuthi zenzeke kusetyenziswa iindlela zokuvavanya ezichanekileyo. Oku kuthembeka kubalulekile kwizicwangciso zomthetho kunye nezonyango, apho iziphumo zichanekile.
Ukuziqhelanisa: Nangona i-GC-Nks inesiphelo, ezinje ngemfuno yamalungiselelo eesampulu, isenokuhlengahlengiswa ngeendlela zokunikezelwa, eziphucula ukuzinza komhlaba, okuphucula ukuzinza komhlaba.
Kwisishwankathelo, i-GC-MS ithandelwa kuvavanyo lweziyobisi ngenxa yokuziva ungafaniyo nokungafani kwayo, ubuchule bokukuqonda uluhlu olubanzi lwezinto ezibanzi, kunye nokukwazi ukunciphisa i-postals yobuxoki. Ezi mpawu zenza isixhobo esibalulekileyo kwi-Kical Andson useto.
