20 ml izitsha ze-headspace

Izitsha ze-Headspace yiziqukathi ezikhethekile eziklanyelwe ukubamba amasampula okuhlaziya i-gas chromatography, ikakhulukazi uma kusetshenziswa amasu okusampula emkhathini. Izinhlobonhlobo ze-crimp-top ezingama-20mm zisho izitsha ezivulekile ezingama-20mm ezivalwe ngekepisi elicijile. Lezi zitsha zitholakala ngosayizi abahlukahlukene, kanti i-6ml, 10ml, kanye ne-20ml yizona ezivame kakhulu.

Izitsha ze-headspace zenziwe ngengilazi ye-borosilicate ka-Aijiren. Amabhodlela e-screw-neck headspace angu-18 mm anama-screw seal kazibuthe e-CTC masha emakethe ye-headspace lapho izintamo ezicijile zibusa khona.

Izitsha ze-Headspace izinto ezisetshenziswayo ezivame ukusetshenziswa ezivivinyweni zesigaba segesi.  Izitsha ze-Headspace zinokucaciswa komthamo okuhlukile, okuhlanganisa u-6ml, 10ml, 20ml, njll. Sebenzisa isampula evamile yebhodlela ukuze uqinisekise i-headspace eyanele. Ngokuvamile, ivolumu egodliwe kufanele okungenani ibe ngu-50% wevolumu yesampula.

Izinto ze-Headspace Vials ziyingilazi ye-Borosilicate ekhishwayo ephansi enezinga eliphansi lokunweba, ukumelana nokushisa okuphezulu, amandla aphezulu, ukuqina okuphezulu, ukudluliswa kokukhanya okuphezulu kanye nokuzinza okuphezulu kwamakhemikhali. Izitsha ze-Headspace zilungele ukuhlaziywa kwe-headspace yama-solids aguquguqukayo namagesi.

I-Headspace GC iyindlela yokulungiselela eyisampula yokunquma izinhlanganisela eziguquguqukayo kumasampula aqinile nawuketshezi. Ibhodlela lesampula le-Headspace livame ukusetshenziselwa ukuhlolwa kwesigaba segesi.

Izitsha ze-headspace zivame ukuba zinkulu kune-2 mL volumetric flasks ezisetshenziswa kumasistimu amaningi wokusampula oketshezi. Izitsha ze-Headspace zivame ukutholakala ngamakhono angu-10 mL no-20 mL.

Izitsha ze-Headspace zinezicaciso zomthamo ezihlukile, okuhlanganisa u-6ml, 10ml, 20ml, njll. Sebenzisa isampula evamile yesampula ukuze uqinisekise i-headspace eyanele. Ngokuvamile, ivolumu egodliwe kufanele okungenani ibe ngu-50% wevolumu yesampula.

Izitsha ze-Headspace zingakwazi ukumelana namazinga okushisa aphezulu nezingcindezi zangaphakathi ezidingekayo ukuze kuhlaziywe igesi eguquguqukayo. Umbala wezitsha ze-headspace uhlukaniswe ngezinhlobo ezimbili ze-brown and transparent, izitsha ezinsundu zingavikelwa ekukhanyeni, futhi inqubo yokukhiqiza ithatha indlela yokubumba, enezici zodonga oluqinile, amandla aphezulu emishini, futhi akulula ukuphulwa.

I-20mm crimp headspace vial isetshenziswa kakhulu ku-Headspace ne-GC, uhlelo lokusebenza lwe-GCMS. 20mm Aluminium Crimp Cap Cap Seals and Vials iqinisekisa ukuthi isigxivizo esifanele senziwa kulolu hlelo lokusebenza oludingayo.

Izitsha ze-Headspace izitsha zaselabhorethri ezisetshenziselwa ukuhlaziywa kwe-headspace futhi zimelana nokushisa okuphezulu nokugqwala. Izitsha ze-Headspace zenziwe ngengilazi ye-borosilicate ekhishwayo ephansi enokwanda okuphansi, ukumelana nokushisa okuphezulu, amandla aphezulu, ukuqina okuphezulu, ukuhanjiswa kokukhanya okuphezulu kanye nokuzinza kwamakhemikhali aphezulu.

I-vial ye-headspace isetshenziselwa inqubo ye-top - chromatography yegesi. Uma sithola izingxube eziguquguqukayo noma eziguquguquka kancane ezinamaphoyinti abilayo aphezulu, sidinga ukuzifudumeza ukuze zihwamuke phezulu. Kule nqubo, njengoba amasampula oketshezi engaphansi, izinto ezisegesini ephezulu zingalinganiswa ngaphandle kokuthinta uketshezi ku-vial yesampula.

Amabhodlela esampula e-headspace atholakala ngezinhlobo eziyi-10 zamavolumu angu-10mL no-20mL, anezansi eziyisicaba noma eziyindilinga. Ikepisi lika-20mm crimp linikeza uphawu oluhlala luqinisekisiwe. Izitsha ze-Crimping noma ze-screw-top ziyatholakala, ezine-beveled top ukuze kuvalwe uphawu lokuphepha okuphezulu, ubude bentamo emibili buyatholakala, futhi imiklamo ephansi-phansi noma eyindilinga-phansi iyatholakala.

Izitsha ze-Headspace zitholakala ngengilazi ecacile noma e-amber enesisekelo esiyindilinga noma esiyisicaba, uphawu olubomvu olunomkhawulo onama-beveled noma isikwele, noma ukuqedwa kwentambo yesikulufu. Izitsha ze-Headspace, i-septum, namakepisi angathengwa ngamanani ahlukahlukene ngokuhlukana noma ndawonye njengamakhithi alula ukuze alingane nezidingo zakho zaselabhorethri.

I-vial ye-headspace isetshenziselwa inqubo ye-top - chromatography yegesi. Izinto ze-Headspace Vials ziyingilazi ye-Borosilicate ekhishwayo ephansi enezinga eliphansi lokunweba, ukumelana nokushisa okuphezulu, amandla aphezulu, ukuqina okuphezulu, ukudluliswa kokukhanya okuphezulu kanye nokuzinza okuphezulu kwamakhemikhali. Izitsha ze-Headspace zilungele ukuhlaziywa kwe-headspace yama-solids aguquguqukayo namagesi.

Izitsha ze-headspace zingakwazi ukumelana namazinga okushisa aphezulu kanye nezingcindezi zangaphakathi ezidingekayo ekuhlaziyweni kwegesi eguquguqukayo. Ngokuqukethwe kwensimbi okuphansi kakhulu, okukhiphekayo nokuvuzayo, izitsha ze-headspace eziphezulu zihlangabezana nezindinganiso eziphakeme ukuze zihlangabezane nezidingo zakho zokulawula.

Impahla yesampula yesampula ye-headspace ingilazi ye-borosilicate ye-low-extraction, ebonakala ngokukhula okuphansi, ukumelana nokushisa okuphezulu, amandla aphezulu, ubulukhuni obukhulu, ukudlulisa ukukhanya okuphezulu kanye nokuzinza kwamakhemikhali aphezulu. Izitsha ze-Headspace zilungele ukuhlaziywa kwe-headspace yama-solids aguquguqukayo namagesi. I-20mm crimp headspace vial isetshenziswa kabanzi ku-Headspace ne-GC, isicelo se-GCMS.

Izitsha ze-headspace zenziwe ngengilazi ye-borosilicate ka-Aijiren. Ungakhetha emibaleni ecacile noma e-amber. Amabhodlela e-headspace anemicu ekulukulu anobukhulu obuphakathi bodonga obungamamilimitha angu-1.25, anikeza ukwethembeka okukhulu njengoba ingcindezi yangaphakathi ikhula. Amabhodlela e-screw headspace anamakepisi kazibuthe angu-18 mm afanele amasampula e-auto asebenzisa ezokuthutha kazibuthe, kuyilapho izitsha ze-headspace ezi-crimp zingasetshenziswa nezikepisi ze-aluminium.
