Ukuqhutywa kwesampulu ye-PREAP yindlela evumela uhlalutyo lweentambo eziguquguqukayo kwinqanaba legesi ngaphezulu kwesampulu. Le ndlela iluncedo kakhulu kwiisampuli eziqukethe i-novalaties okanye imatriki entsokothileyo kuba inceda ukunciphisa ukwazisa kwenkqubo ye-GC. Ngokuhlalutya kuphela isigaba segesi, isampulu yentloko inokubonelela ngenaliti ecocekileyo kwaye inciphise imfuneko yokulungiselela isampulu yesampulu.
Ufuna ukwazi ngokupheleleyo malunga ne-vial ye-vial, nceda ujonge eli nqaku: Isikhokelo esibanzi kwi-vials ye-EPECE: Iimpawu, ukhetho, ixabiso, kunye nokusetyenziswa
I-Static ye-upspace GC
Kwi-propace ye-propce ye-GC, isampulu ibekwe ngaphakathii-vial evaliweyo, kwaye imiqulu ye-cebaile ivunyelwe ukuba ilungelelaniswe phakathi kolwelo okanye isampulu eqinileyo kunye nenqanaba legesi ngaphezulu kwayo. I-vial ifudunyelelwa ukukhuthaza ukukhutshwa kwee-volits, kwaye emva kwexesha elimiselweyo, inxalenye yerhasi yerhasi ikhutshiwe kwaye igcinwe kwinkqubo ye-GC yohlalutyo.
Iimpawu eziphambili zePasile ye-Gestic GC
I-Equilibrium-isekwe: I-Static Ixhomekeke kuMgaqo-nkqubo wokulingana, apho isahlulo sophindaphindiweyo phakathi kwesampulu kunye nepasice. Oku kuthetha ukuba ukugxila kwabahlalutyisi kwindawo yentloko kuya kuzinza ngokuhamba kwexesha.
Ukulungiswa kwesampulu: Ukulungiswa kwesampulu yesampulu kuyafuneka, kuyenza ibe yindlela ethe tye yokuhlalutya imibandela yokuhlalutya kwiimatriki ezinzima.
Ukufudumeza: I-vial ishushu ukonyusa ukungazinzanga kweendawo ezidityanisiweyo, eziphucula ukukhutshwa kwabo kwindawo entloko.
Izicelo: I-Static Statice GC isetyenziselwa uhlalutyo lweenyibiba ezintsalelayo kwi-chineceuticals, i-flavour iqulathe ukutya kunye neziselo ezisebenzayo (VOCs) kwiisampulu zokusingqongileyo.
Izibonelelo zophawu lwe-Gestic GC
Ukulula: Le ndlela kulula ukuyisebenzisa, efuna izixhobo ezincinci kunye namanyathelo okulungiselela.
Ukuncitshiswa kongcoliseko: Ngokuhlalutya kuphela isigaba se-vapor, umngcipheko wongcoliseko kwizinto ezingezizo ezingezizo zincitshisiwe.
Imvakalelo elungileyo: I-statice ye-static inokubonelela ngemvakalelo eyaneleyo yobuninzi obuninzi obuninzi, ngakumbi xa kufanelekile.
Ukusibekeka kwemida ye-ropcace GC
Ixesha lokulinganisa: Ukufezekisa ulinganiso kunokuthatha ixesha, elinokungalungelanga uhlalutyo lwendlela ephezulu.
Inqunyelwe kwiikona eziguquguqukayo: I-Static ye-static isebenze ngokuyintloko ngenxa yeendlela eziguqukayo; Imithanga engalunganga ayinakumelwa ngokufanelekileyo kwiPROCE.

I-Snamic Propace GC
I-Synamic Propace GC, kwelinye icala, ibandakanya ukuqhubeka nokucoca isampulu ngegesi, ngesiqhelo inium. Le gesi ihamba imijikelezo eguqukayo kwimodeli kwiSigaba seRhasi, apho bavaleleka khona kwaye bajongiwe ngaphambi kokuba banjiwe kwinkqubo ye-GC.
Iimpawu eziphambili zePasi ye-GCEG GC
Ukuqhubeka nokuhlambulula: Kwindawo eguqukayo eguqukayo, igesi ye-interred ngokuqhubekayo ihamba ngesampulu, ithwele imizobo eguquguqukayo kwisigaba segesi.
Uxinizelelo: Iikhomputha ziqokelelwayo ziqokelelwe kumgibe, onokufudunyelwa kamva ukuba uhlaziye ikholamu ye-GC yohlalutyo.
Izicelo: IPasi ye-Eynamic ihlala isetyenziselwa uhlalutyo lwee-volatiles zenqanaba lokulandela amanzi, umoya, kunye neesampulu eziqinileyo, kunye nokumiselwa kweMigaqo-nkqubo yeSolkobaty ephantsi.
IINGXAKI ZOKUGQIBELA I-RESPACE GC
Imvakalelo ephezulu: Ukucoca okuqhubekayo kunye nokudibanisa ii-volaties kunokukhokelela ekuphuculeni ubuntununtunu bokwanda, ukwenzela ukuba kube lufaneleke uhlalutyo.
Uhlalutyo ngokukhawuleza: IPasi ye-enamic ingakhawuleza kuneendlela eziqingqiweyo, ngakumbi iisampulu ezifuna uhlalutyo olukhawulezileyo.
Ukusetyenziswa kwezinto: Le ndlela inokuphatha uluhlu olubanzi lweentlobo zesampulu, kubandakanya iinyibilikisi kunye nolwelo, zenza ukuba kubekho kakhulu.
Ukusibekeka kwemida ye-Serpace GC
Ubunzima: Ukuseta okwesiko elinamandla kunokuba nzima, ukucela izixhobo ezongezelelweyo ezinje ngemigibe kunye neenkqubo zokuhamba kwegesi.
Inokubakho ilahleko: ukuba ayilawulwa ngokufanelekileyo, ukuhlambuluka okuqhubekayo kunokukhokelela ekulahlekelweni kweendawo ezixineneyo, ngakumbi abo banamanqaku abilayo.
