Ukuhlaziywa kwe-HeadSpace kuzwela ikakhulukazi ikhwalithi yohlelo lokubopha uphawu olusetshenziselwa ukuqukethe isampula. Izingcindezi eziphakeme kanye namazinga okushisa aphezulu asetshenziswa adinga izibuko zokusebenza okuphezulu nezinto ezenziwe kabusha. Abahlaziyi abasha abaza emakethe bayaqhubeka nokucindezela imvilophu kulezi zidingo [bheka, iShimadzu HS-20, i-agimadzu hs-20, kanye ne-thermo 7697a (bheka ukucushwa kwe-tray), kanye ne-thermo 7697a (bheka ukucushwa kwesayensi ye-tray) amazinga okushisa afinyelela kwa-300 ° C]. Emazingeni okushisa aphezulu, izibuko ezisezingeni eliphakeme ziyisimo sokuhlaziywa okuvela kabusha mahhala kokungcoliswa kwe-siloxane.
Kungani Khetha i-HeadSpace GC?
Ukuhlaziywa kwe-HeadSpacegesi i-Chromatography (GC) kuyindlela evame ukusetshenziswa amakhompiyutha ajwayelekile ajwayelekile, njengokuqukethwe kotshwala begazi, amakhamishini, nokuhlaziywa kokudla okumnandi. Ukuhlaziywa kwenzalo kungatholakala engxenyeni yesampula eyinkimbinkimbi, kepha ama-analytes ashintshashintsha kakhulu kune-matrix, ngakho-ke ukuhlaziya kwenzalo kungahlukaniswa engxenyeni ye-gaseous (ekhanda) yesampula yesampula. Ngokufaka kuphela amakhompiyutha e-gaseous kwikholomu ye-GC, ungagwema ama-chromathamu angcolile kusuka kumakhompiyutha angafuneki atholakala kwisampula ye-liquid. Ama-Headspace vials kanye nama-cap angamelana nokwakhiwa kwengcindezi kwegesi ku-vial.
Ufuna ukwazi kabanzi ukuthi kungani ama-headpace vials asetshenziswa ku-chromatography ?, Sicela ubheke le Artice:Kungani ama-headspace vials asetshenziswa ku-chromatography? 12 engles
Isikulufa phezulu noma i-crimp-top?
Isikulufa caps for headspace vialsIngabe ukuthuthuka kwakamuva, kwasekuqaleni okuhloselwe ama-porotic robotic arm autosamplers. Bancipha inkinga yokuqothuka kwi-cap-cap yensimbi noma ngensimbi eyinhlanganisela \
I-Aluminium cap. Ama-cap wensimbi enziwe avuselelwa futhi awadingi amathuluzi okusika noma avule ama-vials. Banezingqinamba ezithile nezingqinamba.
Bangasetshenziselwa kuphelaI-10mlkanye nama-20ml vials. Kuningi kakhulu kwevolumu yangaphakathi ye-6ml vial elahlekile entanyeni ebekiwe ye-cap.Screw cap headpace vialsazilungele ukusetshenziswa nge-mechanical robotic arm autosamplers. Intamo yentambo yesikulufo se-vial iwububanzi obuhlukile kunaleso se-crimp top vial, kanye nesikulufa cap vial aswele isigaxa semvelo esakhiwe yi-lip ye-crimp top vial. Lowo hlaka uvame ukusetshenziswa yi-autosampler ukusiza ukuvumelanisa nokuphakamisa i-vial.
Ukuhlola Ubufakazi
Namuhla, ngithanda ukumboza umbuzo engibelokhu ngithola ama-labs we-cannabis enza ukuhlaziywa kwezinsalela ezisele. Le bhulogi kungenzeka ingagcini nje kuphela nge-cannabis labs kodwa futhi isize ama-labs ahlaziye amanye ama-matricis afune ama-solvents asele noma amakhompiyutha aguqukayo. Umbuzo uwukuthi, "Yiluphi uhlobo lwenhlanganisela ye-vial ne-vial cap okufanele silusebenzise ukwenza ukuhlaziywa kwethu?"
Lokhu kubhekisa kwimicu yentambo yesikulufo (18 mm) kanye nama-crimp cap (20 mm) weAma-vials angama-20 ML Headspace (HS). Ngakho-ke esikhundleni sokuncoma nje eyodwa noma okunye okusekelwe ku- "FEEL" noma intengo, sanquma ukuqhuba isilingo esincane ukuqhathanisa ukusebenza kwezitayela ezimbili. Ukuhlolwa kwenzelwe ukuhlaziya amakhompiyutha ambalwa kakhulu aguquguqukayo futhi aqoqe idatha yokuthi lezi zinhlobo ezimbili zama-cap zivimbela kangakanani amakhompiyutha ekuphunyukeni kwe-HS VIAL ngokuhamba kwesikhathi esithile.
Ukulungiswa kwesampuli kufaka ukungeza i-PROPER, iButane, namazinga e-Isobutane ku-N, N-DimethylaceTamide (DMA) kanye ne-α, α, α-trifluoRontolue njenge-ISTD to a20 ml hs vial. Ukumodela amandla we-vial cap okugcina lezi zinhlanganisela eziguqukayo ekuphunyukeni kwe-vial, sahlela ukutadisha isikhathi. Kulolu cwaningo, amasampula ayi-14 alungiselelwe uhlobo ngalunye lwe-vial futhi amasampula ahlukaniswe abe amasethi amabili angu-7. Setha eyodwa (T0) ngokushesha ngemuva kokuthi amasampula alungiswe futhi ahlelwe amabili (T6) ngemuva kwamahora ayisithupha. Kufanele futhi kuqashelwe ukuthi ingcindezi ye-crimp cap yahlelwa ukumodela ukuqina kwesikopele. Lokhu kusho ukuthi inani le-torque elidingekayo ukususa isikulufa cap kufana ne-torque edingekayo ukuze kuthathwe i-climp ehleliwe, crimp cap.
Isibalo esijwayelekile sendawo kusuka ku-T0 kuya ku-T6 kuqhathaniswa nokubala ukulahleka kwamaphesenti okulingana esikhathini esingamahora ayisithupha. Umehluko wamaphesenti ahlukahlukene ngohlobo ngalunye lwe-HS VIAL lungabonakala ku-3.
Ukusuka kwimininingwane ekhonjiswe kuMdwebo 3, siyabona ukuthi isikulufa caps (aluhlaza okwesibhakabhaka) asizange sibe uphawu naku-T6 kuye ku-T6 uma kuqhathaniswa nama-chemp cap (abomvu). Kuhle futhi ukuqaphela ukuthi sibona ushintsho oluncane kakhulu ku-Istd yethu esikhathini esingamahora ayi-6 sobabili isikulufa cap kanye ne-climp cap.
Ngemuva kokubheka imininingwane futhi ngithathe konke, ngicabanga ukuthi kwanele ukusho ukuthi uma usebenza ngelebhu ukwenza ukuhlaziywa kwe-HS kwezindawo eziguquguqukayo (amagesi), kufanele ube usebenzisa ama-chemp cap. Kodwa-ke, noma ngabe kusetshenziswa ama-Crimp CAPS, umuntu asadinga ukuqaphela iqiniso lokuthi amakhompiyutha alula, athambile, njengezinhlanganisela eziboniswe lapha, zisakwazi ukubalekela i-HS VIAL. Manje, ngakho konke lokhu kushiwo, angifuni ukunikeza umbono wokuthiscrew cap hs vialsazinamsebenzi. Zingasetshenziswa nakanjani ekuhlaziyweni kwe-HS, ikakhulukazi uma amakhompiyutha ehlaziywa asohlangothini oluncane olushintshashintshayo noma isikhathi sakho ekuhlelweni kwesampula ukuze uhlaziywe. Njengesibonelo Bheka umehluko omncane we-α, α, α-trifluoRotoluene, ngakho-ke kumakhasimende amaningi ehlaziya uhlu olujwayelekile lwama-solvents kanye nama-voliles screw cap angafaneleka.

Ezinye izinto ezi-5 ezidinga ukucubungula lapho ukhetha i-headpace vial cap
Ukufaneleka ngokwezinto ezibonakalayo
Omunye wokucatshangelwa okuyisisekelo lapho ukhetha aI-headpace vial cap ukuhambisana kwezinto ezibonakalayo ngezinto zayo zomsingathi. Ama-headspace vials ngokuvamile aqukethe ingilazi ngenkathi ama-cap angavela ezintweni ezahlukahlukene ezinjenge-aluminium, i-silicone, ne-PTFE (polytetrafluoroethleleneene). Ngokufanelekile, khetha i-inert cap engasebenzisana nesampula noma impahla yakho ye-vial ukugwema ukungcoliswa noma ukulahleka kokuhlaziywa, kuqinisekisa imiphumela eqondile yokuhlaziya.
Ukukhetha Septum
Ukuvikela amasampula ekungcolisweni yindawo ezungezile, avalwe kusetshenziswa i-septum, esebenza njengolwelwesi oluncane phakathi kokuqukethwe kwalo kanye nomoya. Inaliti evunyelwe evunyelwe ingadlula ngenkathi usalondoloza uphawu lwe-Airtitight. Izinhlobo eziningi zeSepta zikhona njenge-silicone,Ptfe \
abikone, ne-butyl rubber; Ukukhetha kwabo ngokuvamile kuncike eMvelweni nasenhlosweni yokuhlaziywa kwenziwa; ngenjwayeloabicane septazilungele izinhloso eziningi ngenkathi amakhompiyutha aguqukayo noma asebenzayo, ezinye izindlela ezifanele ezifana ne-PTFE \
silicone nomaI-Burty rubleingahle ithandeke.
Ukuqina kwegesi
Ukuhlaziywa kwe-HeadSpace kuthembela kuma-airtight main ukuvimba ukulahleka kwamakhompiyutha aguqukayo nokungcoliswa kwemvelo yangaphandle. Ngakho-ke, ukukhetha izigqoko ngokuqina kwegesi okuhle kakhulu ukuze uqinisekise ukuthi i-septum yakha uphawu olufanele nge-vial lubalulekile ukuqinisekisa imiphumela yokuhlaziya ephephile. Ezinye izimbobo zesikhungo sezici ze-CAPS ezivumela ukungena kwenaliti ngaphandle kokulimaza sepum Seals ngcono ukuthuthuka kwegesi.
Ukushisa nokushisa kwengcindezi
Ukuhlaziywa okuthile kudinga amazinga okushisa aphezulu noma ingcindezi ngaphakathi kwe-vial, okwenza kudingekile ukukhetha ama-cap ama-caps akwazi ukubekezelela lezi zimo ezimbi kakhulu ngaphandle kokufaka engcupheni ubuqotho bayo njengophawu lwayo njengophawu lwalo njengophawu. Qiniseka ukuthi ufunde konke ukucaciswa okunikezwe ngumenzi ngamunye we-cap ukuze uqiniseke ukuthi kuzohlangabezana nazo zonke izidingo zakho zokushisa nezidingo zokucindezela.
Ukuhambisana ne-automation
I-automation iye yanda kakhulu kwizilungiselelo zelebhu, okwandisa ukusebenza kahle ngenkathi kunciphisa iphutha lomuntu. Uma uhlela ukushintshanisa ukuhlaziya i-headspace usebenzisa ama-robotic systems, ukukhetha ama-cap ahambelana nemishini yabo ezenzakalelayo efana naleyo efakwe izici ezinjengezimbozo ezihlaba umxhwele noma izimbotshana ezibucayi zibalulekile ekusebenzeni kahle nezinqubo zokuhlaziya kahle zihamba kahle.
Yini okufanele uyinake
Uma kukhulunywa ngokukhetha i-cap efanele yakhoI-HeadSpace vial, kubalulekile ukunaka izinto ezinjengokuhambisana kwezinto ezibonakalayo nge-vial, uhlobo lwe-septa, indlela yokuvalwa, ukuhambisana kwezindleko, njengoba lezi zindleko, ukucatshangelwa kwengcindezi, njengoba kucatshangelwa izindleko ngokuhlanganyela kunokubambisana Imiphumela enembile nethembekile ekuhlaziyweni kwegesi chromatographic.
