I-Headspace GC (Gas Chromatography) izitsha zesampula ezikhethekile ezisetshenziswa ekuhlaziyweni kwe-headspace. Ukuhlaziywa kwe-Headspace kuyindlela esetshenziswa kukhemikhali yokuhlaziya ukuze kuhlaziywe izinhlanganisela eziguquguqukayo kusampula.
Ekuhlaziyweni kwe-headspace, isampula lifakwa ku-vial evaliwe, futhi izinhlanganisela eziguqukayo kusampula zilingana ne-headspace (isikhala esingenhla kwesampula) ngaphakathi kwe-vial. Ibhodlela libe selishiselwa kuzinga lokushisa elithile, okubangela ukuba amakhompiyutha aguquguqukayo ahwamuke futhi asabalalise endaweni yekhanda.

Izitsha zengilazi ze-GC ze-headspace borosilicate glass, ezaziwa nangokuthi izitsha ze-gas chromatography headspace, ziyizitsha ezikhethekile eziklanyelwe ukuhlaziya izinhlanganisela eziguquguqukayo kusetshenziswa indlela yokusampula ye-headspace ku-gas chromatography (GC).
Izitsha ezisetshenziselwa ukuhlaziywa kwe-headspace ku-chromatography yegesi ngokuvamile zenziwe ngengilazi ye-borosilicate noma ezinye izinto ezingasebenzi njengengilazi ephathwe ngokukhethekile noma izinhlobo ezithile zama-polymer. Lezi zitsha zenzelwe ukumelana namazinga okushisa aphezulu kanye nezingcindezi ezihilelekile kunqubo yesampula ye-headspace.

Izitsha ze-Headspace ziwuhlobo lwezitsha zaselabhorethri ezisetshenziselwa ukuhlaziya i-gas chromatography. Zenzelwe ukuqukatha umthamo omncane wesampula kanye ne-headspace (isikhala esingenhla kwesampula) sokuhlaziywa kwezinhlanganisela eziguqukayo. Lawa mabhodlela ngokuvamile anekepisi eliyisikulufu eline-septum, elivumela ukujova igesi noma inaliti ukuze kuthathwe isampula. Izitsha ze-headspace zisetshenziselwa ukuhlaziya ama-volatile organic compounds (VOCs) kumasampuli ahlukahlukene, njengamasampula emvelo, ezokwelapha, kanye nokudla.
Izitsha ze-GC ngokuvamile zenziwa ngengilazi noma ngezinye izikhathi zepulasitiki, futhi ziza ngobukhulu obuhlukahlukene kanye nokwakheka ukuze zivumelane namavolumu amasampula ahlukene nezindlela zomjovo. Bavame ukuba ne-screw cap ene-septum, evumela umjovo wesampula noma inaliti yokwenza isampula.

Izitsha ze-Headspace ziwuhlobo lwesiqukathi sesampula esisetshenziswa kukhemistri yokuhlaziya, ikakhulukazi ukuhlaziya i-headspace. Ukuhlaziywa kwe-Headspace kuhilela ukuhlaziywa kwezinhlanganisela eziguquguqukayo ezikhona esigabeni segesi ngaphezu kwesampula. Lezi zinhlanganisela eziguquguqukayo zivame ukuba nentshisekelo ezinhlelweni ezifana ne-gas chromatography (GC) noma i-gas chromatography-mass spectrometry (GC-MS).
Izitsha ze-Headspace ziklanyelwe ukubamba isampula futhi zenze indawo evalekile yesigaba somhwamuko ngaphezu kwesampula. Izitsha ngokuvamile zenziwe ngengilazi, nakuba izitsha zepulasitiki ziyatholakala. Izitsha zinomthamo othize wevolumu, ongasukela kumamililitha ambalwa ukuya emashumini amaningana amamililitha, kuye ngesicelo.

I-20ml ye-crimp top headspace vial iwuhlobo lwe-vial evame ukusetshenziswa ezinhlelweni ze-gas chromatography (GC) ukuze kuhlaziywe izinhlanganisela eziguquguqukayo nezingama-volatile. Idizayinelwe ngokukhethekile ukusampula kwe-headspace, okubandakanya ukukhipha inhlanganisela eguquguqukayo kusampula eqinile noma ewuketshezi iye esigabeni segesi ukuze sihlaziywe.Kubalulekile ukuqaphela ukuthi imininingwane ethile kanye nezidingo zokusebenzisa ibhodlela le-crimp top headspace ingahluka kuye ngohlelo lwe-GC nokuhlaziywa okwenziwayo.

I-septa yerabha engu-18mm ngokuvamile ibhekisela ohlotsheni lokuvala olusetshenziswa kuzilungiselelo zaselabhorethri. I-septa yerabha ivamise ukwenziwa ngezinto ezifana ne-silicone noma irabha yokwenziwa futhi iklanyelwe ukuvala iziqukathi ezifana nezitsha noma amabhodlela. Zivame ukusetshenziselwa izinhlelo zokusebenza lapho isampula idinga ukugcinwa noma ihlaziywe ngaphansi kwezimo ezilawulwayo.I-Rubber septa inikeza umgoqo osebenzayo we-TEMP ngokumelene nomoya kanye nomswakama, ukuvimbela ukungcola nokugcina ubuqotho be-teh besampula ye-teh. Avame ukusetshenziswa ezindaweni zokucwaninga ngezinhlelo zokusebenza ezifana ne-gas chromatography, i-liquid chromatography, isampula yokulondoloza, noma amanye amasu okuhlaziya.

I-20mm GC vial decapper\/vial crimper iyithuluzi eliguquguqukayo elisetshenziswa ezilungiselelweni zemithi nezaselabhorethri ukususa amakepisi noma ama-crimping aluminium seals ku-20mm GC (Gas Chromatography) ithuluzi. 20mm GC izitsha.

I-20mm GC vial decapper\/vial crimper iyithuluzi eliguquguqukayo elisetshenziswa kuzilungiselelo zezemithi nezaselabhorethri ukuze kukhishwe amakepisi noma ama-crimping seal e-aluminium kumabhodlela angu-20mm GC (Gas Chromatography). Ihlanganisa ukusebenza kwe-decapper kanye ne-vial crimper ibe idivayisi eyodwa.Ithuluzi elihlanganisiwe le-decapper ne-vial crimper livame ukusetshenziswa ekuhlanganiseni kwemithi, ilabhorethri yocwaningo.
