Ukukhetha ama-autosampler vials kanye nama-cap ngokuhlaziywa kwe-HPLC & GC

Ku-HPLC ne-GC, ukukhetha kwama-vials kanye nama-cap kubalulekile ukuqinisekisa imiphumela enembile nethembekile. I-vial isitsha sesampula esifakwe ku-chromatograph, futhi ukwakhiwa kwayo kunomthelela omkhulu ekuhlaziyeni. Le ngxoxo izokwamboza izinhlobo ezahlukahlukene ze-HPLC kanye ne-GC vials kanye nama-cap, izinto zazo, izici, kanye nokukhethwa kokukhethwa. I-AIJIREN AUTOSAMPLER VIALSZilungele i-HPLC, LC \ MS, GC, kanye ne-GC \ MS MIPLENTS kanye nezinhlelo zokusebenza.

Ufuna ukwazi izimpendulo ezingama-50 mayelana ne-HPLC VIALS, sicela uhlole le ndatshana: Imibuzo evame ukubuzwa kaningi ku-HPLC VIALS

Izinhlobo ze-HPLC ne-GC Autosampler VIAL

1. Screw cap vials

Screw cap vialszingenye yezinto ezisetshenziswa kakhulu kuzinhlelo zokusebenza ze-HPLC. Banentambo enomugqa engabekwa uphawu kalula nge-screw cap. Zingavulwa kalula futhi zivaliwe, okulungele ukulungiswa kwesampula. Ihambisana nama-autosamplers amaningi, ikhulisa izinga lokuzenzakalela elabhorethri. Ilungele kakhulu ukuhlaziya okujwayelekile okudinga ukufinyelela okusheshayo kumasampula. Ukushisa kokusebenza kwebhodlela kungaphansi kwe-100 ℃ kanti i-cap ingaphansi kuka-90 ℃.

2. Crampimp top vial

Crimp top vialszibekwa uphawu nge-climp cap ukuqinisekisa ukuvalwa okuphephile. Isikhundla se-septum sihlala singashintshiwe lapho inalithi yokujova ye-autosampler ihlaba isampula. Inqubo ebomvu ye-crimp top vial iveza uphawu olunzima, olubalulekile kumasampula aguqukayo angahle avele. I-Crimp Top Vials ilungele kangcono izinhlelo zokusebenza zengcindezi ephezulu ngoba zinciphisa ubungozi bokuvuza ngaphansi kwengcindezi. Imvamisa isetshenziswa kuzinhlelo zokusebenza ezidinga ukuzwela okuphezulu noma lapho uphatha amakhompiyutha aguqukayo.

3. Snap top vial

Snap-on vialsbahlome nge-cap-on snap-on ukuvalwa okusheshayo nokuvikelekile ngaphandle kokuqhekeka noma ukuqina. I-Snap-on vials kulula ukuyivula futhi ivale, okwenza babe nobungane. Imvamisa kushibhile kune-crimp top vials.

I-Snap top vials ilungele ukusetshenziswa kwelabhoratri okujwayelekile lapho ukuguquguquka kwesampula kungeyona inkinga enkulu.

4. I-Micro

Ama-vials amancaneyizincane zesampula zesampula ezenzelwe amasampula aphansi kakhulu (imvamisa ngaphansi kwe-1 ml). Ukufakwa okuncane kungasetshenziswa nge-screw cap, crimp cap, noma i-snap cap vials. Amajamo aphansi ahlukene ayatholakala, kufaka phakathi phansi phansi, phansi, kanye ne-conical phansi nge-poly Spring.

Ukufakwa kwe-Micro Khulisa ukutakula amasampula futhi wenze ukususwa kwesampula kube lula uma kusetshenziswa nge-autosampler vials ngoba ukwakheka kwe-conical kunciphisa indawo engaphezulu kwe-vial.

E fnoma imininingwane engaphezulu ngama-autosampler vials we-chromatography yegesi, bhekani le ndatshana: 2 ml autosampler vials we-chromatography yegesi

Izinto ezisetshenziselwa i-HPLC kanye ne-GC Vials

1.

Ingilazi ye-borosilicate isetshenziswa kabanzi ngenxa yokumelana kwayo kwamakhemikhali nokuvuselelwa okuphansi. I-inerteness inciphisa ukungcoliswa kwesampula. Izakhiwo ezibonakalayo zivumela ukuhlolwa okubonakalayo kokuqukethwe. Ingilazi ye-amber isetshenziselwa ikakhulukazi amasampula abucayi akhanyayo ukuvikela okuqukethwe kusuka ekunciphiseni kwe-UV.

2. Ipulasitiki vial

I-polypropylene noma ama-polyethylene vials ahlukile ngengilazi. I-PolyPropylene, i-PP iyipulasitiki engasebenzi kahle engasetshenziswa lapho ingilazi kungeyona inketho. Ama-polypropylene vials angagcina uphawu oluhle lapho ashiswa ngomlilo, ngaleyo ndlela anciphise ukuvezwa kwezinto ezingaba yingozi. Izinga lokushisa elisebenzayo lingu-135 ° C. Ama-polypropylene vials angasindi futhi ahamba nge-shatetterproof, okwenza baphephe ukukusebenzisa.

Ukukhetha kohlobo lweSepta

Ptfe \ abicone septaIlungele imijovo eminingi kanye nesitoreji sesampula. Kusetshenziswa kabanzi ngenxa yokumelana kwayo kwamakhemikhali kanye nekhono lokumelana nama-puncture amaningi. Ngaphambi kokubhoboza, inokumelana kwamakhemikhali kwe-PTFE, nangemva kokubhoboza, i-septum izohambisana namakhemikhali we-silicone. Izinto ezisebenza ngezinto eziningi ze-septum eziguquguqukayo, ezingenziwa ngokwezifiso ngobulukhuni obuhlukahlukene ukuze bahlangabezane nezidingo zezinaliti ezahlukahlukene, ukukhetha kokuqala kwezicelo eziningi ze-GC \ hplc.

Pre-cut ptfe \ abikoneihlinzeka ngomoya omuhle ukuvikela ukwakheka kwe-vacuum ebhodleleni lesampula, ngaleyo ndlela uzuze ukufeka kwesampula okuhle kakhulu. Gwema inkinga yokubhoboza okunzima, futhi ngemuva kokuqhubeka kokujova, ingcindezi ngaphakathi nangaphandle kwe -vumayo ingalinganiswa ngaphandle kwengcindezi engemihle.

Ukucatshangelwa kokukhetha i-autosampler isampula ama-vials nama-cap

Lapho ukhetha ama-VPLC & GC autosampler vials kanye nama-cap, lezi zinto ezilandelayo kufanele zibhekwe:

1. Uhlobo lwesampula (i-volatile vs. non-floulatile) luzothinta ukukhetha kohlobo lwe-pastle yesampula. Ngezinhlanganisela eziguquguqukayo, kunconywa ukusebenzisa ibhodlela lesampula ye-crimp ngophawu oluvikelekile ukuvikela ukuhwamuka.

2. Khetha usayizi we-vial osampula ngokuya ngenani lesampula ovame ukuhlaziya. IVolumu yesampula, elikhulu umthamo ongadinga.

3. Qinisekisa ukuthi i-vial ekhethiwe iyahambisana nemodeli yakho ye-autosampler ethile ukugwema izinkinga ngokuphathwa kwesampula ezenzakalelayo.

I-4. Lapho ukhetha uhlobo lwe-vial lwe-septum ne-Septum, cabanga ngezakhiwo zamakhemikhali zesampula ukugwema ukusabela okungathinta imiphumela.

Wan ukwazi ulwazi oluphelele lokuthi ungahlanza kanjani i-Chromatography Sampula ama-vials, sicela uhlole le ndatshana: Esebenzayo! Izindlela ezi-5 zokuhlanza i-chromatography isampula ama-vials

Ungayikhetha kanjani ivolumu yomjovo ye-2ml autosampler vial?

Isiphetho esingezansi senaliti yomjovo kufanele kube ngu-2 ~ 3mm kusuka ezansi kwei-autosampler vial; Uma isampula lincane kakhulu, kunconywa ukusebenzisa ukufaka okuncane ku-autosampler vial.

Uma kunamasampula amaningi, i-1ml yanele. Kuningi kakhulu kungadala kalula ezinye izinkathazo ezingadingekile. IVolumu yesampula lincane, ngokuvamile cishe ngo-0.3ml. Uma ivolumu yesampula ingaphansi kuka-0.3ml, kunconyelwa ukufaka ukufaka okuncane. Kunconywa ukugcina ukuphakama kwenaliti yomjovo njengoba kunjalo. Akunconyelwe ukuguqula ukuphakama kwenaliti ngentando. Uma ukuphakama kweminye imikhiqizo yezinaliti zomjovo kulungiswa ngokungesikho, inaliti ingahle yeqa futhi yehluleke ukujova isampula.

Ngokufingqa, ukukhetha okulungileI-HPLC GC VIALSkanye nokuvalwa kubalulekile ekufezekiseni imiphumela ethembekile yokuhlaziya. Ukuzikhethela phakathi kwesikulufu, ama-crimp cap, ama-snap caps, noma ama-vials amancane ancike kwizidingo ezithile zelebhu, kufaka phakathi uhlobo lwesampula, izidingo zevolumu, kanye nokuhambisana nama-autosamplers. Ngokwengeziwe, ukucubungula ngokucophelela okuqukethwe (noma ngabe ingilazi noma ipulasitiki) nohlobo lokuvalwa kuzothuthukisa ubuqotho besampula ngesikhathi sokuhlaziywa. Ngokuqonda lezi zinto, ama-laboratories angakhulisa ukuhamba kwawo kwe-Chromatography futhi athuthukise ukusebenza kahle kwenqubo yokuhlaziya.
