Sonke siyazi ukuba izinto zokupakisha emva kokuprinta zinevumba elahlukileyo, kuxhomekeke kwindlela eyenziwe ngayo i-inki nendlela yokuprinta.
Okokuqala, kufuneka kuqatshelwe ukuba ugxininiso alukho kwivumba elinjani, kodwa kwindlela ukupakisha okwenziwe ngayo emva kokuprinta okuchaphazela ngayo umxholo womxholo wayo.
Umxholo wezinyibilikisi ezisele kunye nezinye ivumba ezikwiipakethe eziprintiweyo unokufunyanwa ngendlela echanekileyo ngohlalutyo lwe-GC.
Kwi-gas chromatography, nokuba yigesi encinci inokubonwa ngokudlula kwikholamu yokwahlulahlula kwaye ilinganiswe ngumtshini wokuxilonga.
Isixhobo sokufumanisa i-ionization yelangatye (i-FID) sisixhobo esiphambili sokufumanisa. Isixhobo sokufumanisa siqhagamshelwe kwiPC ukuze sirekhode ixesha kunye nobungakanani begesi ephuma kwikholamu yokwahlulahlula.
Ii-monomers ezikhululekileyo zinokuchongwa ngokuthelekiswa ne-fluid chromatography eyaziwayo.
Okwangoku, umxholo we-monomer nganye yasimahla ungafunyanwa ngokulinganisa indawo yencochoyi erekhodiweyo uze uyithelekise nomthamo owaziwayo.
Xa kuphandwa ityala lee-monomers ezingaziwayo kwiikhathoni ezigoqiweyo, i-gas chromatography idla ngokusetyenziswa kunye ne-mass method (MS) ukuchonga ii-monomers ezingaziwayo nge-mass spectrometry.
Kwi-gas chromatography, indlela yohlalutyo lwe-headspace idla ngokusetyenziswa ukuhlalutya ibhokisi egoqiweyo, isampuli elinganisiweyo ifakwa kwi-vial yesampuli kwaye ifudunyezwe ukuze i-monomer ehlalutyiweyo itshiswe kwaye ingene kwi-headspace, ilandelwe yinkqubo efanayo yovavanyo echazwe ngaphambili.
