Sonke siyazi ukuthi izinto zokupakisha ngemva kokuphrinta zinamazinga ahlukene okunuka, kuye ngokuthi ukwakheka kweyinki nendlela yokunyathelisa.
Okokuqala, kufanele kuqashelwe ukuthi ukugcizelelwa akukhona ukuthi iphunga linjani, kodwa ukuthi ukupakishwa okwakhiwa ngemva kokunyathelisa kuthinta kanjani okuqukethwe kwayo.
Okuqukethwe kwezinyibilikisi ezisele kanye nezinye iphunga kumaphakheji aphrintiwe kunganqunywa ngokunembile ngokuhlaziywa kwe-GC.
Ku-chromatography yegesi, ngisho nenani elincane legesi lingatholwa ngokudlula kukholomu yokuhlukanisa futhi likalwe ngomtshina.
Umtshina we-ionization wamalangabi (FID) iyithuluzi eliyinhloko lokuthola. Umtshina uxhumeke ku-PC ukuze urekhode isikhathi kanye nenani legesi eliphuma kukholomu yokuhlukanisa.
Ama-monomers amahhala angakhonjwa ngokuqhathanisa ne-chromatography yoketshezi eyaziwayo.
Phakathi naleso sikhathi, okuqukethwe kwe-monomer ngayinye yamahhala kungatholwa ngokulinganisa indawo ephakeme erekhodiwe futhi uyiqhathanise nevolumu eyaziwayo.
Lapho kuphenya icala lama-monomer angaziwa emakhathoni agoqiwe, i-gas chromatography ivamise ukusetshenziswa ngokuhambisana nendlela yobuningi (MS) ukuze kuhlonzwe ama-monomer angaziwa nge-mass spectrometry.
Ku-chromatography yegesi, indlela yokuhlaziya i-headspace ivamise ukusetshenziselwa ukuhlaziya ikhathoni eligoqiwe, isampula elilinganisiwe lifakwa ku-vial eyisampula futhi lishiselwe ukuze lihwamulise i-monomer ehlaziywe futhi ifake i-headspace, ilandelwe inqubo efanayo yokuhlola echazwe ngaphambili.
