Izitsha ze-Headspace ziwuhlobo lwezitsha zaselabhorethri ezisetshenziselwa i-gas chromatography. Aklanyelwe ukuqukatha amasampuli azohlaziywa kusetshenziswa i-headspace gas chromatography, indlela esetshenziselwa ukuhlaziya izinhlanganisela eziguquguqukayo kumasampuli aqinile noma awuketshezi. Izitsha zivaliwe nge-septum cap, okuvumela indawo yekhanda engenhla kwesampula ukuthi ihlaziywe ngaphandle kokuveza isampula emkhathini. Le nqubo ivame ukusetshenziswa ekuhlaziyeni imithi, imvelo, nokudla, phakathi kweminye imikhakha.
Izitsha ze-Headspace, ezaziwa nangokuthi izitsha ze-gas chromatography (GC) noma izitsha zesampula, ziyiziqukathi ezikhethekile ezisetshenziselwa ukuhlaziya izinhlanganisela eziguquguqukayo ku-chromatography yegesi. Adizayinelwe ukugcina amasampuli futhi adale i-headspace ngaphezu kwesampula, equkethe izingxenye eziguqukayo okufanele zihlaziywe.

I-GC headspace vial, eyaziwa nangokuthi i-gas chromatography headspace vial, iwuhlobo lwesampula yebhodlela esetshenziswa ekuhlaziyeni kwe-headspace. Ukuhlaziywa kwe-Headspace kuyindlela esetshenziswa ku-gas chromatography (GC) ukuze kuhlaziywe izinhlanganisela eziguquguqukayo noma eziguquguquka kancane ezikhona kusampula.
Ibhodlela le-headspace yakhelwe ngokukhethekile ukubamba isampula futhi idale indawo evalekile ukuze ihlaziywe. Iqukethe ibhodlela lengilazi eline-crimp noma i-screw cap. Ibhodlela ngokuvamile linendawo engezansi eyindilinga noma eyikholi ukuze kube lula ukukhishwa komoya endaweni yekhanda.

Izitsha zeHeadspace 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.

Isikulufu sebhodlela lengilazi sisho uhlobo lwesiqukathi esenziwe ngengilazi esinesikulufu esivala noma indlela yokuvala. Lezi zitsha zivame ukusetshenziselwa ukugcina nokuthutha izinto ezihlukahlukene, njengoketshezi, izimpushana, noma amasampula amancane aqinile, kwezesayensi, kwezemithi, nasezimbonini zokusebenza.
I-screw-on cap iqinisekisa isivalo esivikelekile nesingena moya, sivimbela okuqukethwe kwe-vial ukuthi kungavuzi noma kungcoliswe. Lesi sici sibaluleke kakhulu lapho ugcina izinto ezizwelayo noma ezibalulekile ezidinga ukuvikelwa kumswakama, emoyeni, noma ezinye izici zangaphandle.

I-Test Tube yitemu elingasho izinto ezihlukene kuye ngomongo. Ngomongo wesayensi, ishubhu lokuhlola ingilazi eyisilinda noma ishubhu lepulasitiki elisetshenziselwa ukubamba futhi kuxube amanani amancane oketshezi ngesikhathi sokuhlolwa kulabhorethri. Isetshenziswa kakhulu ku-chemistry, biology, kanye nezinye iziyalo zesayensi.
Ngomqondo obanzi, i-“Test Tube” ingaphinda ibhekisele esiteshini se-YouTube esibizwa ngokuthi “TestTube,” okuyisiteshi esidumile sesayensi nezemfundo esiphethwe yi-Discovery Digital Networks. Lesi siteshi sihlanganisa izihloko eziningi ezihlanganisa isayensi, ubuchwepheshe, umlando, namasiko, futhi sihlinzeka ngamavidiyo afundisayo najabulisayo kubabukeli.

I-10\/20 mL isikulufa se-headspace vial iwuhlobo lwesiqukathi saselabhorethri esivame ukusetshenziswa kukhemistri yokuhlaziya kanye nezicelo zemithi.
Idizayinelwe ngokukhethekile ukuhlaziywa kwezinhlanganisela eziguquguqukayo kusampula kusetshenziswa indlela ebizwa ngokuthi ukuhlaziywa kwe-headspace.
Ibhodlela lifaka intamo eyisikulufu, okusho ukuthi inombobo oyintambo ovumela ukuvala okuvikelekile kusetshenziswa ikepisi noma i-septum.
Idizayini yentamo eyisikulufa iqinisekisa ukuvala okuqinile, ivimbela noma yikuphi ukuvuza kwesampula noma ukuphuma kwezinhlanganisela ezishintshashintshayo phakathi nokuhlaziywa.

10ml 20ml Headspace GC izitsha ziwuhlobo lwesampula lwebhodlela elisetshenziswa ekuhlaziyeni i-gas chromatography (GC).
Zakhelwe ngokukhethekile ukuhlaziya izinhlanganisela eziguquguqukayo nezingashintshashintshashintshashintshayo ezikhona kusampula.
Ukuhlaziywa kwe-Headspace kuhilela ukukhishwa kwezinhlanganisela eziguquguqukayo kusuka kusampula okuqinile noma okuwuketshezi ukuya esigabeni segesi ukuze kujovelwe ethuluzini le-GC.
20mm amakepisi e-aluminium kanye ne-septa avame ukusetshenziswa ezinhlelweni ze-chromatography, okuhlanganisa i-gas chromatography (GC) kanye ne-high-performance liquid chromatography (HPLC). Asetshenziselwa ukuvala izitsha zesampula futhi aqinisekise ukuthi i-gas-tight noma i-liquid-tight seal.

Amabhodlela aselabhorethri angu-10ml 20ml kanye nezitsha zivame ukusetshenziswa ocwaningweni lwesayensi nasezinhlelweni ezihlukahlukene zaselabhorethri.
Izitsha ze-Headspace ziwuhlobo oluthile lwezitsha zaselabhorethri eziklanyelwe ukuhlaziywa kwezinhlanganisela eziguquguqukayo ku-gas chromatography (GC) kanye ne-gas chromatography-mass spectrometry (GC-MS).
Kubonakala sengathi ubhekise ezinhlotsheni ezimbili zezitsha zaselabhorethri:
10ml kanye no-20ml ngezikulufu zezitsha ze-headspace ezenziwe nge-amber noma ingilazi ecacile, ezinamakepisi e-aluminium.

I-10 ml 20 ml ye-headspace vial iwuhlobo olukhethekile lwe-vial esetshenziswa ekuhlaziyeni kwe-gas chromatography (GC) ukuze kuhlaziywe izinhlanganisela eziguqukayo.
Idizayinelwe ukubamba isampula ku-headspace, okuyisigaba segesi ngaphezu kwesampula ewuketshezi noma eqinile.
Ukuhlaziywa kwebhodlela lesikhala sekhanda lamagesi akhona ezitsheni zesampula yesikhala sekhanda, amabhodlela aselabhorethri okuhlaziya isikhala sekhanda abizwa ngokuthi izitsha ze-head space.
Ukuze uthole imiphumela enembile, Siphinde sibe nezidingo ezithile zamabhodlela esampula kanye ne-septa.

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.
