Sonke siyazi ukuthi izinto zokupakisha ngemva kokuphrinta zinephunga elihlukile, kuye ngokuthi uyinki unjani kanye nendlela yokuphrinta.
Okokuqala, kufanele kuqashelwe ukuthi ukugcizelela akukhona ukuthi iphunga linjani, kodwa ukuthi iphakethe elenziwa ngemva kokunyathelisa lithinta kanjani okuqukethwe kwalo.
Okuqukethwe kwezithako ezisele kanye nezinye iphunga emaphaketheni aphrintiwe kunganqunywa ngokunemba ngokuhlaziywa kwe-GC.
Ku-gas chromatography, ngisho nenani elincane legesi lingatholakala ngokudlula kukholomu yokuhlukanisa bese kulinganiswa ngumtshina.
I-flame ionization detector (FID) iyithuluzi eliyinhloko lokuthola. I-detector ixhunywe kwi-PC ukuze irekhode isikhathi kanye nenani legesi eliphuma kukholamu yokuhlukanisa.
Ama-monomer amahhala angabonakala ngokuqhathaniswa ne-chromatography yoketshezi eyaziwayo.
Okwamanje, okuqukethwe kwe-monomer ngayinye yamahhala kungatholakala ngokulinganisa indawo ephakeme eqoshiwe bese uyiqhathanisa nomthamo owaziwayo.
Uma kuphenywa icala lama-monomer angaziwa emabhokisini agoqiwe, i-gas chromatography ivame ukusetshenziswa kanye nendlela yobuningi (MS) ukuhlonza ama-monomer angaziwa nge-mass spectrometry.
Ku-gas chromatography, indlela yokuhlaziya i-headspace ivame ukusetshenziswa ukuhlaziya ibhokisi eligoqiwe, isampula elilinganisiwe lifakwa ebhodleleni lesampula bese lishiswa ukuze kushiswe i-monomer ehlaziyiwe bese ingena e-headspace, kulandelwe inqubo efanayo yokuhlola echazwe ngaphambilini.
