Ukukhetha i-vials ye-autosampler kunye neCAPS ye-HLPC & GC

Kwi-HPLC ne-GC, ukhetho lwee-vials kunye ne-CAPS kubalulekile ukuqinisekisa iziphumo ezichanekileyo nezinokuthenjwa. I-vial sisikhongozeli kwimodeli enamathele kwi-chromatograph, kwaye uyilo lwayo lunefuthe elibonakalayo kuhlalutyo. Le ngxoxo iya kuhlawula iintlobo ezahlukeneyo ze-HLLC kunye ne-GC Vials kunye neCAPS, izixhobo zabo, iimpawu kunye nokuqwalaselwa kokukhetha. I-Aijiren Vials Vialszilungele i-HPLC, i-LC \ / Nks, GC, kunye ne-GC \ /Ms Izixhobo kunye nokusetyenziswa.

Ufuna ukwazi iimpendulo ezingama-50 malunga nee-vials vials, nceda ujonge eli nqaku: I-50 kakhulu imibuzo ebuzwa rhoqo kwi-vials ye-HPPL

I-HPLC & GC I-Automampler Vial vial

I-1. Screw cap vials

Isikhafu se-capyenye yezona vils ezisetyenziswa kakhulu kwizicelo ze-HPLC. Banentamo enentambo enokutywinwa ngokulula ngesikrelemnqa. Banokuvulwa ngokulula kwaye bavale, nto leyo efanelekileyo kwilungiselelo lesampulu. Ihambelana ne-amosamplers, yonyusa inqanaba le-automation elebhu. Ilungele kakhulu uhlalutyo olukhawulezileyo olufuna ukufikelela ngokukhawuleza kwiisampuli. Amaqondo obushushu okusebenza kwibhotile engezantsi kwe-100 ℃ kunye ne-cap ingaphantsi kwe-90 ℃.

I-2. I-crimpp ephezulu ye-vial

I-crimpp ephezulu ye-vialszitywinwe nge-crmp cap yokuqinisekisa ukuvalwa okukhuselekileyo. Isikhundla seSeptum ihlala ingaguqukanga xa inaliti ye-autosampler ye-awnasler ibhobhoza isampulu. Inkqubo yokuqhekeza ye-CRIMP ivelisa itywina elinzima, elibaluleke kakhulu kwiisampulu eziguqukayo ezinokuthi iphume. I-crimpp i-vials ephezulu ilungele ukusetyenziswa kwezicelo zoxinzelelo oluphezulu kuba zinciphisa umngcipheko wokuvuza phantsi koxinzelelo. Ihlala isetyenziswa kwizicelo ezifuna ubuntununtunu obuphezulu okanye xa uphatha imilinganiselo ye-quiyile.

I-3. Snap ephezulu vial

I-Snap-kwi-vialszixhotywe nge-snap-kwi-cap yokuvalwa ngokukhawuleza kunye nokukhuselekileyo ngaphandle kokuqhekeza okanye ukuqinisa. I-Snap-kwi-vials kulula ukuyivula kwaye ivale, ibenze lula ukuba ibe nomsebenzisi. Ihlala inexabiso eliphantsi kune-crmps ephezulu ye-vials.

I-snap vils ephezulu ilungele ukusetyenziswa kwelebhu ngokubanzi apho isampulu yokuguquliswa ayisiyonto iphambili.

4. I-vial vil

I-vials ezincincizii-vials ezincinci zesampulu ezenzelwe iisampulu zevolumu eziphantsi kakhulu (zihlala zingaphantsi kwe-1 ml). Ukufaka i-Micro faka kunokusetyenziswa ngesikhafu se-screw cap, i-crmp cap, okanye i-snap cap. Iimilo ezahlukileyo ezisezantsi ziyafumaneka, kubandakanya ezantsi, kumyohla, kwaye ezantsi kwe-poly yentwasahlobo.

Ukufaka i-Micro faka ukwandisa isampula yokufumana isampula kwaye wenze isampulu kulula xa isetyenziswe nge-autosammar vials kuba imilo ye-comcise inciphisa indawo engaphakathi kuyo.

FOkanye ulwazi oluthe kratya kwi-vials ye-autosampler ye-chromatography, ibhekisa kweli nqaku: I-2 ml automampler vials ye-chromatography yegesi

Izixhobo ezisetyenziselwa i-HLLC kunye ne-GC Vials

I-1. I-Borossililicicate yeglasi

Iglasi ye-borossilicate isetyenziswe ngokubanzi ngenxa yokungaxhathisi kunye nokuhlala okuphantsi. I-Intertty inciphisa isampulu yongcoliseko. Ipropathi ebonakalayo ivumela uvavanyo olubonakalayo lwesiqulatho. Iglasi ye-Amber ikakhulu isetyenziselwa iisampulu ezibuthathaka zokukhusela ukhuselo kwi-UV Degradiyation.

I-2. I-vial yeplastiki

I-Polypropylene okanye i-vialthylene i-polyethylene yenye yeglasi. I-Polypropylene, i-PP yiplastiki engasebenziyo enokusetyenziswa apho iglasi ayisiyo inketho. I-vials i-polypropylene inokugcina itywina elihle xa litshiswe ngomlilo, ngaloo ndlela kuncitshiswa ukubonakaliswa kwezinto ezinokubakho. Elona qondo lobushushu liphezulu yi-135 ° C. I-Polypropylene Vials iphosakele kwaye i-sutterproof, ibenza bakhuseleke ukuze basebenzise.

Ukukhetha uhlobo lweSepta

Ptfe \ / isilicone Septazilungele inaliti ezininzi kunye nokugcinwa kwesampulu. Isetyenziswe ngokubanzi ngenxa yokungaxhathisi bayo kunye nokukwazi ukumelana noxinzelelo oluninzi. Phambi kokutyela, ikwaxhathisa i-PTFI yekhemikhali ye-ptfe, kwaye emva kokuphuculwa, iSeptum iya kuba nekhemicokheli ye-silicone. Ezona zinto zininzi ze-septum ze-septum ze-septum, ezinokwenziwa ngokwezixhobo zobunzima bokufezekisa iimfuno zenaliti ezahlukeneyo, lukhetho lokuqala kwizicelo ezininzi ze-GC / pllictions.

I-PAR-CICFF PTFA \ / SiliconeInika umoya ofanelekileyo wokuthintela ukwenziwa kwe-vacuum kwibhotile yesampula, emva koko ukufezekiswa ngokuzala kwesampulu. Kunqande ingxaki yokuhlaselwa nzima, kwaye emva kwenaliti eqhubekayo, ingcinezelo ngaphakathi nangaphandle kwe i-vial inokulungelelaniswa ngaphandle koxinzelelo olubi.

Ukuqwalaselwa kokukhetha i-awsammar yesampulu ye-awsampler kunye ne-caps

Xa ukhetha i-HLLC & GC I-Autialr Vials kunye neCAPS, ezi zinto zilandelayo kufuneka ziqwalaselwe:

I-1. Uhlobo lwesampulu (i-villaile vs. Ngeenkcukacha eziguqukayo, kuyacetyiswa ukuba isebenzise ibhotile ye-crmimp yetywina elikhuselekileyo ukuthintela ukuvela.

2. Khetha isampulu yesampulu ngokwesixa sesampulu ohlala uhlalutya. Ukukhululeka komthamo wesampula, kuya kufuna isampulu yevolumu.

3. Qiniseka ukuba i-vial ekhethiweyo iyahambelana nemodeli yakho ye-autosampler ye-autosampler yokuphepha iingxaki ngexesha lokuphathwa kwesampula.

4. Xa ukhetha i-Vial Tools kunye nohlobo lweSeptum, qwalasela iipropathi zeekhemikhali zesampulu ukunqanda ukuphendula okunokuchaphazela iziphumo.

I-Wan Ukufumana ulwazi olupheleleyo malunga nendlela yokucoca i-vialsgraphy yesampulu ye-chromatography, nceda ujonge eli nqaku: Iyasebenza kakuhle! Iindlela ezi-5 zokucoca iimodeli ze-chromatographys

Ungayikhetha njani ivolumu yenaliti ye-2ml autoMampler vial?

Isiphelo esisezantsi senaliti yenaliti kufuneka ibe yi-2 ~ 3mm ukusuka ezantsi kweI-autosampler vial; Ukuba isampulu incinci kakhulu, kuyacetyiswa ukuba isebenzise i-Micro vial vial vial vial.

Ukuba zininzi iisampulu, i-1ml yanele. Kakhulu inokubangela ezinye iingxaki ezingeyomfuneko. Ivolumu yesampulu incinci, ngokubanzi ijikeleze i-0.3ml. Ukuba ivolumu yesampulu ingaphantsi kwe-0.3ml, kuyacetyiswa ukongeza i-Microbar. Kucetyiswa ukugcina ukuphakama kwenaliti yenaliti njengoko kunjalo. Akucetyiswa ukuba uhlengahlengise ukuphakama kwenaliti. Ukuba ukuphakama kwezinye iimpawu zenaliti zilungiswa ngokungachanekanga, inaliti inokutsiba kwaye isilele ukuyifaka isampulu.

Ngesishwankathelo, ukukhetha ilungeloI-HPLC GC Vialskwaye ukuvalwa kubalulekile ekufezekiseni iziphumo ezinokuthenjwa. Ukukhetha phakathi kweCAPS yeCarw, i-CRIMP CAPS, i-SNAP CAPS, okanye i-vials ezincinci kuxhomekeke kwiimfuno ezithile zelebhu, kubandakanya ne-autosamplers. Ukongeza, ukuthathelwa ingqalelo ngononophelo kwento (nokuba iglasi okanye iplastiki) kunye nohlobo lokuvalwa kuya kuphucula ukuqiniseka kwesampulu ngexesha lohlalutyo. Ngokuqonda ezi zinto, iilebhu ziyakwazi ukwenza i-chromatography yazo yokusebenza kunye nokuphucula ukusebenza kwenkqubo yohlalutyo.
