Qonda izilinganiso zokucindezela ze-headpace vial

Yini izilinganiso zokucindezela ze-headpace?

Izilinganiso zibhekisela ekucindezelweni okukhulu kwe-vial zingamelana ngokuphepha. Lokhu kucindezela kubhekiselwa ekucindezelweni ngesikhathi sokuhlaziywa. Lezi zilinganiso zibalulekile. Ngesikhathi sokushisa ku-chromatography yegesi, ingcindezi esesimweni ingavuka kakhulu. Usebenzisa i-vial ngesilinganiso sokucindezela okuphansi kakhulu kungaholela ekuqhekekeni noma ukuvuza. Lokhu kungalimaza isampula kanye nemiphumela.

1. Izinto ezibonakalayo nokwakha

I-Glass Vials:Iningi le-HeadSpace vials lenziwa ngengilazi ye-borossilte. Yaziwa ngokuqina kwayo nokumelana nokushaqeka kwe-thermal. Ubukhulu nekhwalithi yengilazi banquma isilinganiso sengcindezi ye-vial. Ingilazi ye-borosilate iyathandwa. Inokunwetshwa okuphansi okushisayo. Lokhu kunciphisa ingozi yokuqhekeka ngaphansi kokushintsha amazinga okushisa.

UCAP noSepta:I-cap ne-petata nayo idlala indima ebalulekile.Iziqeshanazivame ukwenziwa kusuka ku-aluminium noma ngensimbi. I-Septa yenziwa ngezinto zokwenziwa njenge-PTFE noma i-silicone. Kufanele bakha uphawu oluvikelekile ukuze bagcine ekucindezelweni. I-CAP kumele ibambe i-Septaly kahle. Lokhu kuvimbela ukuvuza ngesikhathi sokucindezela nokushisa ekuhlaziyeni.

2. Ukubekezelela ingcindezi

Izilinganiso ezijwayelekile:Ama-Headspace Valial eza nezilinganiso ezihlukile zokucindezela. Lezi zilinganiso zivame ukusuka ku-15 PSI kuya ku-45 psi noma ngaphezulu. Isilinganiso esithile sincike ngosayizi we-vial, impahla, kanye nomenzi.Ama-vials aphezulu wengcindezeloYenzelwe izinhlelo zokusebenza ezinezidingo eziphakeme. Lezi zinhlaka zenzelwe amakhompiyutha aguquguqukayo noma amazinga okushisa aphezulu.

Ukuhlola kanye nesitifiketi:Abakhiqizi bahlola ama-vials ukuze baqinisekise ukuthi bahlangabezana nezilinganiso ezicacisiwe zengcindezelo. Sebenzisa njalo ama-vials aqinisekiswe amazinga okucindezela adingekayo. Ukuqinisekiswa kuqinisekisa ukuthi ama-vials ahlolwe kanzima. Bangakwazi ukwenza ngokuthembekile ngaphansi kwezimo ezisethiwe.

Amathiphu wokunquma ama-vials alinganiswe ngengcindezelo

Ukukhetha ingcindezi efanelekileama-headspace vialsukhiye. Bazothinta ukunemba nokuphepha kokuhlolwa kwakho kwe-chromatography yakho. Nawa amanye amathiphu wokukusiza ukhethe ama-vial afanele.

1. Qonda izidingo zakho zokuhlaziya

Uhlobo lwesampula:Cabanga ngohlobo lwesampula owahlaziya. Amakhompiyutha aguqukayo angakhiqiza izingcindezi eziphakeme, ezidinga izilinganiso ezinezilinganiso eziphakeme zengcindezelo. Isibonelo, amasampula ane-ethanol ephezulu noma amanye ama-solvents anamaphoyinti aphansi. Bangakhulisa ngokusheshe ukucindezela ku-vial.

Izimo Zokushisa:Nquma izimo zokushisa ngesikhathi sokuhlaziywa. Amazinga okushisa aphezulu aholela ekucindezelweni okungaphakathi okuphezulu. Lokhu kusho ukuthi ama-vial anokubekezelelana okuphezulu kwengcindezi ephakeme ayadingeka. Uma ukuhlaziywa kwakho kufaka amazinga okushisa aphezulu, qiniseka ukuthi ama-vials akho angawaphatha. Akumele baphule.

2. Bheka imininingwane yomenzi

Izilinganiso zokucindezela:Hlola ama-specs womkhiqizi wezilinganiso zengcindezi ye-vials. Qiniseka ukuthi ama-vial okhethayo angaphatha ingcindezi elilindelekile. Ukucaciswa komenzi kuzofaka namazinga okushisa aphezulu anconyiwe neminye imininingwane efanele.

Ukuvumelana okubonakalayo:Bheka i-vial, cap, kanye nezinto zokwakha. Udinga ukuqiniseka ukuthi ziyahambisana nesampula yakho nokuhlaziywa. Amasampula angasabela ngendlela ehlukile ngezinto zokwakha. Ngakho-ke qinisekisa ukuthi ukuhambisana kuvimbela ukonakaliswa kwesampula nokungcola.

3. Yenza izivivinyo zokuqala

Ukuhlolwa kuyabaleka:Zivivinywa kuqala. Sebenzisa okumbalwaama-vialsukubona ukusebenza kwabo. Yenza lokhu ngaphansi kwezimo zakho ezithile. Lokhu kusiza ukukhomba noma yiziphi izingqinamba ezingaba khona ngokubekezelelana kwengcindezelo ngaphambi kokuhlaziya okugcwele okugcwele. Ukuhlolwa kokuqala kungaveza izindaba ezinjengokuvuza, ukuqhekeka kwe-vial, noma ukuwohloka kwesampula.

Qapha ukuvuza:Ngalezi zivivinyo, bukela noma yikuphi ukuvuza noma ukuguquguquka kwe-vial. Lokhu kukhombisa isilinganiso sokucindezela kungaphansi kakhulu. Ukuvuza kungaholela ekulahlekelweni kwesampula kanye nemiphumela emibi. Ukuguqulwa kungakhombisa ukuthi izinto ezibonakalayo azikwazi ukuphatha ingcindezi.

4. Factor kuma-margins okuphepha

Khetha izilinganiso eziphakeme:Uma ungabaza, khetha izipesheli ngezilinganiso eziphakeme zengcindezelo kunokuba udinga. Lokhu kunikeza umugqa wokuphepha, ukunciphisa ingozi yokwehluleka kwe-vial ngesikhathi sokuhlaziywa. Isilinganiso sokucindezela esiphakeme siqinisekisa ukuthi izipesheli zingaphatha izingcindezi eziphakeme ngokungazelelwe. Lokhu ngeke kulimaze ubuqotho besampula.

Cabanga ukulinganiselwa kwemishini:Qiniseka ukuthi isampula yakho ye-HeadSpace neminye imishini ingaphatha ama-vial akhethiwe. Kufanele ziphephe izilinganiso zengcindezi ye-vial. Cabanga ngemikhawulo ye-OWIPT. Lokhu kuzogwema ukwenza ngokweqile izipesheli nokulimaza izinsimbi.

5. Hlola njalo bese ubeka esikhundleni se-vials

Hlola ngaphambi kokusebenzisa:Hlola ngaphambi kokusebenzisa. Ngaphambi kokusetshenziswa ngakunye, hlola ama-vials wokuqhekeka noma amaphutha. Lokhu kunganciphisa ukubekezelela kwabo ingcindezi yabo. Ngisho nokungapheleli okuncane kungase kubucayi ngaphansi kwezimo eziphakeme kakhulu.

Ukungena ngesikhathi:Faka esikhundleni se-vials, izigqoko, ne-pepta kaningi. Lokhu kuzobenza basebenze kahle futhi baphephile. Ngokuhamba kwesikhathi, ukusetshenziswa okuphindaphindiwe kungalimaza ukumelana kwabo kwengcindezi. Ukubuyiselwa okujwayelekile kuqinisekisa ukuthi ama-vials ahlala ethembekile futhi aphephile ukusetshenziswa.

6. Ukuqeqeshwa kanye nemikhuba emihle kakhulu

Fundisa abasebenzi beLab:Qiniseka ukuthi bonke abasebenzi beLab baqeqeshelwe ukukhetha nokuphatha kahle ama-headspace vial kahle. Ukuqeqeshwa okufanele kunciphisa ubungozi bamaphutha futhi kuthuthukise ukuphepha. Maningi amathuba okulandela imithetho. Bangabona izingqinamba ngaphambi kokuba babe yizinkinga.

Landela imikhuba emihle kakhulu:Hlangana nemikhuba emihle kakhulu yokulungiswa kwesampula, ukubekwa uphawu kwe-vial, nokusingathwa. Lokhu kuzokwengeza ubuqotho kanye nokunemba kwemiphumela yakho. Imikhuba emihle kakhulu ifaka usebenzisa amathuluzi aphezulu aqophayo. Futhi, gwema ama-vials agcwaliseke ngokweqile futhi uzigcine kahle.

Ukugcina

Ukuqonda izilinganiso zengcindezelo ye-vial kubalulekile. Babalulekile ekusebenziseni okuphephile futhi okusebenzayo kwelezi zintokugesi i-chromatography. Cabanga ngezinto ezifana nezinto ezibonakalayo nokwakha. Futhi, bheka ukubekezelelana nengcindezelo kanye nokucaciswa komenzi. Ngokwenza lokhu, ungakhetha izipesheli ezifanele zezidingo zakho. Kufanele senze izivivinyo zokuqala. Kufanele futhi kufanele sibe yizici zemishado yokuphepha. Ngaphandle kwalokho, kufanele sihlole njalo ama-vials. Lezi zinyathelo ziqinisekisa imiphumela ethembekile nenembile. Ukuqeqeshwa okufanele nokulandela imikhuba emihle kakhulu kubalulekile. Bayisihluthulelo sokuthola imiphumela emihle kakhulu ekuhlaziyiweni kwakho kwe-chromatography yakho. Ukukhetha ama-headpace vials afanele agcina abasebenzi belebhu baphephile. Iphinde ithuthukise imiphumela yakho ngokuzenza zithembeke ngokwengeziwe futhi ziphinde zenzeke.
