Uhlobo lwe-vial luthinta kanjani ukuhlaziywa kwamakhompiyutha ezi-organic aguqukayo

Lapho uhlaziya ama-compacts avuthayo we-organic (ama-Vocs) usebenzisa i-chromatography yegesi (GC), ikakhulukazi amasu wesampula e-headpace, ukukhetha kohlobo lokuvula lwe-vial kuyinto ebalulekile. Ukucushwa kokuvulwa kwe-vial kunomthelela omkhulu ekusebenzeni kwesampula, ubuqotho bokuhlaziywa, kanye nokunemba kwemiphumela yokugcina yokuhlaziya. Le ndatshana ifakazela ukuthi izinhlobo ezahlukene ze-vial zingathinta kanjani ukuhlaziywa kwe-VOC futhi ziveze ukucatshangelwa okubalulekile kwabaphenyi kanye nabacwaningi belebhu.

Ukuqonda izinhlobo ezahlukene ze-vial cap

Uhlobo lwentamo ye-vial lubhekisela ngokuyinhloko ekwakhiweni nosayizi wokuvulwa okuphezulu kwe-vial. Ukucushwa okujwayelekile kungokulandelayo:

Screw-top vials: Ama-vials ngentamo enomugqa kanye ne-cap yesikulufa ephezulu yokuvalwa okuphephile. Ziyathandwa kalula ukusetshenziswa kwazo nokusebenzisa umoya, okubalulekile ekugcineni ubuqotho besampula.

Ama-vial-ap: Lezi zinhlamvu zinentamo ebushelelezi futhi zidinga ithuluzi eliqhelelekile ukuvikela i-cap yensimbi kurabha noma nge-silicone Septum. Lo mklamo uhlinzeka ngophawu oluhle kakhulu lokuvimbela ukulahleka kwe-VOC futhi lulungele amasampula aguqukayo.

Snap-top vials: Lezi zinhlaka zine-cap ye-snap-top ngokufinyelela okusheshayo, kepha ungahlanganisi kanye nezinsimbi-phezulu noma ama-crimp-top vials. Lezi ngokujwayelekile zisetshenziselwa amasampula amancane aguqukayo.

Ufuna ukwazi ngokugcwele nge-infor mayelana ne-Headspace Vial, sicela uhlole le ndatshana:Umhlahlandlela ophelele wezinhloko ze-Headspace: Izici, Ukukhetha, intengo, nokusebenzisa

Ithonya lohlobo lwebhodlela lesampula ekuhlaziyweni kwe-VOC

Ukukhethwa kohlobo lwentamo ye-vial kuthinta izici eziningana zokuhlaziywa kwe-VOC.

1. Isampula ubuqotho kanye nokuguquguquka

Enye yezinto ezikhathazayo eziphambili lapho ukuhlaziya ama-vocs kugcina ubuqotho babo kuyo yonke inqubo yokuhlampula nokuhlaziywa. Uhlobo lwentambo ye-vial kudlala indima ebalulekile ekuvikeleni ukuhwamuka.

Ama-Vials ahlanganisiwe: Idizayini enomucu ihlinzeka nge-seal eliqinile, ukunciphisa ubungozi bokuvuza kwe-VOC ngesikhathi sokugcina nokuhlaziywa. Lokhu kubaluleke kakhulu kumasampula angakuzwela ukuvezwa komkhathi.

Ama-Crimp Vials: Izimpawu ze-crimp zinikeza uphawu lwe-airtight, ukunciphisa amandla okulahleka kwe-VOC ngokuhwamuka. Lokhu kubalulekile lapho ubhekene nezinto eziguquguqukayo kakhulu eziphunyuka kalula emkhathini.

Snap cap vials:Snap capzilula, kepha musa ukusayina kanye noma izikulufa noma ama-crimp cap

2. Ukuphathwa kahle kwesampula

Idizayini ye-Vial Feat Design ibuye ithinta kalula ukulungiswa kwesampula kanye nokuhlaziywa.

Ama-vials ahlanganisiwe: Lezi zimo ezilula zisebenzise futhi zingavulwa ngokushesha futhi zivalwe ngaphandle kwamathuluzi akhethekile. Lokhu kulula kokusebenzisa kube lula ukuhamba komsebenzi endaweni ematasa.

I-Crimp Top Vials: I-Crimp Top Vials Seal Well kahle kepha idinga imishini eyengeziwe (ithuluzi le-crimp) ukubopha nokuvula, okunganciphisa isikhathi sokucubungula isampula.

I-Snap Top Vials: Idizayini elula ivumela ukufinyelela okusampule okusheshayo, kepha lokhu kube lula kufanele kubhekwe ekulweni nezinkinga ezingaba khona ngobuqotho bezinsampula.

3. Ukuvumelana kwe-Autosampler

Amalebhu amaningi asebenzisa ama-autosamplers ukuze afake ngokuzenzakalelayo amasampula ezinhlelweni zawo ze-GC. Uhlobo lwe-vial force kubalulekile ukuze luhambisana namadivayisi alandelayo:

Ama-Vials ahlanganisiwe: Ama-Autosamplers amaningi enzelwe ukuhambisana nomthungo zibe ngama-threaded vials, uqinisekise ukusebenza okungaguquki lapho kujova amasampula.

I-Crimp Top Vials: Amanye ama-autosamplers angahlalisa ama-crimp aphezulu, kepha akuwona wonke amamodeli. Kubalulekile ukubheka ukuhambisana ukugwema izingqinamba ngesikhathi sokuhlaziywa.

I-Snap Top Vials: Snap top vials ayisebenzi ngayo yonke i-autosamplers njengoba inganikezi uphawu oluhle futhi kungaholela ekunikezelweni kwesampula okungahambisani.

Okunye ukucatshangelwa

Kunezinye izinto eziningana okufanele zicatshangelwe ngaphandle kohlobo lwentamo lapho ukhetha i-headpace vial yokuhlaziywa kwe-VOC.

1.

Izinto ezisetshenziselwa i-Septum (ingxenye ephilwa yinalithi) ibaluleke kakhulu.Abicane septa zisetshenziswa kabanzi ngenxa yokumelana nayo kwamakhemikhali kanye nekhono lokugcina uphawu oluhle emazingeni okushisa athile. Qiniseka ukuthi izinto zokubopha zihambisana ne-VOC ethile ehlaziywe.

2. I-VIAL PRACE

Umthamo we-headpace ngenhla kwesampula ye-liquid kubalulekile ukuze ulingane ngempumelelo phakathi kwezigaba eziwuketshezi negesi. Ama-vials amakhulu ngokuvamile ahlinzeka ngekhanda elithe xaxa, elikhulisa ukuzwela kokuthola amakhompiyutha aguqukayo.

I-3. Ukuqina kokushisa

Okunye ukucatshangelwa ukuthi ngabe i-vial ingamelana nokushintshashintsha kwamazinga okushisa ngesikhathi sokuhlaziywa. Amanye ama-Vocs kumele afudunyezwe ngesikhathi sokuhlaziywa, ngakho-ke i-vial eyisampula kufanele ikwazi ukugcina ubuqotho bayo ngaphansi kwalezi zimo ngaphandle kokulahlekelwa uphawu lwayo noma ukuvuza.

Ngolwazi oluthe xaxa ngama-autosampler vials we-chromatography yegesi, bhekani le ndatshana: 2 ml autosampler vials we-chromatography yegesi

Ngamafuphi, ukukhethwa kwesampula ye-Vial Mouth Uhlobo kunomthelela omkhulu ekuhlaziyeni kwamakhompiyutha aguqukayo we-organic yi-chromatography yegesi. Izici ezinjengobuqotho besampula, ukusetshenziswa kalula, ukuhambisana kwe-autosampler, kanye nezinto zokwakha uphawu konke kudlala indima ebalulekile ekuqinisekiseni ukunemba nokwethenjwa kwemiphumela.

Abaphenyi kanye nochwepheshe belebhu kufanele bahlole kahle lezi zici lapho bekhethaama-headspace vials Ukuhlaziywa kwe-VOC. Ngokubeka phambili imiklamo ye-vial engavalwa ngokuqinile, efana nama-screw-cap vials noma cindezela-cap vials, ama-laboratories anganciphisa ukulahleka kwezinto eziguquguqukayo futhi athuthukise ukusebenza kokuhlaziya.
