Tonsefe tikudziwa kuti zinthu zopakira pambuyo posindikiza zimakhala ndi fungo losiyanasiyana, kutengera kapangidwe ka inki ndi njira yosindikizira.
Choyamba, ziyenera kudziwika kuti cholinga chachikulu si fungo lake, koma momwe phukusi lomwe limapangidwa pambuyo posindikiza limakhudzira zomwe zili mkati mwake.
Zomwe zili mu zosungunulira zotsalira ndi fungo lina pa mapaketi osindikizidwa zitha kudziwika bwino pogwiritsa ntchito kusanthula kwa GC.
Mu gasi chromatography, ngakhale mpweya wochepa ukhoza kupezeka podutsa m'mbali yolekanitsa ndikuyesedwa ndi chowunikira.
Chowunikira cha ionization ya moto (FID) ndiye chida chachikulu chodziwira. Chowunikiracho chimalumikizidwa ku PC kuti chilembe nthawi ndi kuchuluka kwa mpweya womwe ukutuluka mu gawo lolekanitsa.
Ma monomers aulere amatha kuzindikirika poyerekeza ndi chromatography yodziwika bwino yamadzimadzi.
Pakadali pano, zomwe zili mu monomer iliyonse yaulere zitha kupezeka poyesa dera la nsonga yolembedwa ndikuyerekeza ndi voliyumu yodziwika.
Pofufuza nkhani ya ma monomers osadziwika m'makatoni opindidwa, gas chromatography nthawi zambiri imagwiritsidwa ntchito limodzi ndi njira ya mass (MS) kuti azindikire ma monomers osadziwika pogwiritsa ntchito mass spectrometry.
Mu gasi chromatography, njira yowunikira malo a mutu nthawi zambiri imagwiritsidwa ntchito pofufuza katoni yopindidwa, chitsanzo choyezedwacho chimayikidwa mu botolo la chitsanzo ndikutenthedwa kuti chitenthetse monomer yowunikidwayo ndikulowa mu malo a mutu, kutsatiridwa ndi njira yoyesera yomweyi yomwe tafotokoza kale.
