I-20mm i-aluminium caps kunye ne-septa zisetyenziswa ngokuqhelekileyo kwizicelo zechromatography, kubandakanywa i-chromatography yegesi (GC) kunye ne-high-performance liquid chromatography (HPLC). Zisetyenziselwa ukutywina iibhotile zesampula kunye nokuqinisekisa i-gas-tight okanye itywina eliqinileyo.

Uhlalutyo lwe-Headspace lubandakanya ukutsalwa kweekhompawundi eziguquguqukayo ukusuka kwisampulu eqinileyo okanye emanzi kwisigaba segesi yokutofa kwisixhobo seGC.
Kubalulekile ukuba uqaphele ukuba iinkcukacha ezithile ze-vial, ezifana nomthamo, uhlobo lwentambo, kunye noyilo lwe-cap, lunokwahluka phakathi kwabavelisi kunye nababoneleli. Ke ngoko, kuyacetyiswa ukuba ujonge imveliso ethile okanye uqhagamshelane nomthengisi ukuze ufumane ulwazi oluchanekileyo malunga ne-18mm screw top headspace borosilicate glass glasses ocingayo.

I-vial ye-headspace isetyenziswe kwinkqubo ephezulu - i-chromatography yegesi. Xa sibona imixube eguquguqukayo okanye engaguquguqukiyo enamanqaku aphezulu abilayo, kufuneka siyifudumeze ukuze ivuthe phezulu. Kule nkqubo, ekubeni iisampuli zolwelo zisezantsi, izinto ezikwigesi ephezulu zinokulinganiswa ngaphandle kokuchukumisa ulwelo kwisampulu yesampulu.

Ezi 20mm ezibunjiweyo zesepta kunye nezithinteli ze-butyl ezingwevu zibonelela ngokutywinwa kokusebenza okuzinzileyo kwiingqayi zaselabhoratri. Ulwakhiwo lwabo olungqingqwa lwe-3mm luqinisekisa ukungena kwenaliti ethembekileyo, izinto ezikhutshwayo eziphantsi kunye nokhuseleko lwesampulu ecocekileyo. Ifanelekile ukuhlalutya rhoqo, ukulungiswa kweesampuli kunye nezicelo zokugcina.

Uhlalutyo lwe-ND20 ye-headspace lunokwenziwa ngokusebenzisa iindlela ezahlukeneyo, ezifana ne-static headpace, i-headpace eguquguqukayo, kunye nokucoca kunye nomgibe.
