I-chromatography, njengendlela yohlalutyo, ifuna izixhobo ezichanekileyo nezixhobo zeziphumo ezichanekileyo. Inxalenye enye ihlala ijongeka ngaphandle kwentsingiselo ebalulekileyo kwi-vialsgraphy ye-chromatographyI-Septa itywina-Iitywina ezincinci kodwa ezibalulekileyo kodwa ezibalulekileyo ezibaluleke kakhulu ekugcineni ingqibelelo kunye nokuqinisekisa uhlalutyo oluphumeleleyo. Siza kuphonononga zonke izinto ezikhoyo zeSepta kunye nepropathi yazo eyahlukileyo ukuze ukhethe umntu ofanelekileyo kwiimfuno zakho zohlalutyo lweChromatographic. Esi sikhokelo sibanzi, siza kuphonononga olu kukhetho olukhulu lweSepta esinalo ngokunikezela namhlanje kwaye kufanelekile ukuyikhetha impumelelo yokuphononongwa kwempumelelo ye-chromatographic.

Ukubaluleka kweSepta kwiChromatography

I-Septa yindawo engenakuphikwa kwi-vialsgraphy ye-chromatography, idlala uluhlu lweendima ezibalulekileyo:

Ingxibenga yesampulu: I-Septa isebenza njengabakhuseli wentembeko yesampulu, ebonelela ngokhuseleko kungcoliseko kunye nokuphuma.

Itywina eliqinileyo le-gesi

Ukukhetha

I-Interges yekhemikhali: Kwisampulu ephezulu okanye uhlalutyo, i-Septa kufuneka ibonise i-dictuls diserty.

Ndinomdla wokukhetha phakathi kwe-pre-slit okanye i-septa engeyiyo i-sepga? Fumana iimpendulo zakho kweli nqaku:Yintoni i-vial vial sepga?

Iindidi ezi-5 eziqhelekileyo ze-Septa

1. Silicone
YayoI-Silicone SeptaNgaba ukhetho oluqokelelweyo kakhulu, lulungele ngokufanelekileyo izicelo ezininzi ezahlukeneyo. Bancothulwe ngokubanzi kwiPropathi yabo ebalaseleyo-ilungele ukuphindaphinda intsholongwane - ukubenza bakhulule kwi-chromatography yegesi njengoko bekwazi ukumelana nobunzima; Nangona kunjalo basenokungalungeli kuhlalutyo olubuthathaka kakhulu ngenxa yemicimbi yokungcola enokubakho.

2. Polytetraflum)

I-Ptfe Septa yaziwa ngokubanzi kwi-Intertureji yazo yekhemikhali kwaye inamanqanaba asezantsi, ibenza bagqibelele kwizicelo eziphezulu zobuntu obunengxaki yokusebenza kwi-chromatography (i-HPPC). Babonisa ukunganyangeki kuluhlu lweekhemikhali kunye nezinyibilikisi kodwa abanakuphatha ngokufezekileyo njenge-silicone septa.

I-3. I-Butyl Ruber

I-Butyl Rubber Septa isetyenziswe ngokubanzi kwipropathi yabo yokuqhelanisa, ibenze ukuba zikhethe izinto ezithandwayo kwihlalutyo le-6. Banokujamelana nobushushu obubanzi buye bahlukane nokunganyangeki ekulahleni - umba oqhelekileyo xa ujongile ulwelo oluphezulu-ngaphandle kokufumana intsholongwane yeekhemikhali kwiI-Ptfe Septa.

5. Izinto ezikhethekileyo

Ukongeza kwizinto zeSepta zeSintu, iSepta eyodwa inokuthi ilungiswe ngokuthe ngqo kwiimfuno ezithile, kubandakanya i-polyethylene, i-polyproplene kunye ne-vitmon (R). Ukhetho lwabo luxhomekeke kwiimfuno zomntu ngamnye.

Ukuqwalaselwa xa ukhetha izixhobo zeSepta

Xa ukhetha izixhobo zeSepta ukuze zisetyenziswe kwi-vialsgraphy ye-chiatosgraphy, thabatha le micimbi iphambili:

Isampulu yokuhambelana: Khetha izinto zeSepta ezihambelana neempawu zesampulu.

Isicelo: Iindlela ezahlukeneyo ze-chromatographic zinokunyanzelisa izixhobo zeSepta ezithile. I-PAALDE: Kwinaliti ezininzi, khetha i-septa kunye ne-septages ebalaseleyo.

Ukuxhathisa ubushushu: Kubalulekile ukuba iSepta ingakwazi ukumelana namaqondo obushushu asetyenziselwa uhlalutyo lwakho.

Ukukhetha izinto ezifanelekileyo zeSeptaI-chialsgraphy ye-chromatographysisigqibo esibalulekileyo esinefuthe elikhulu ekuthembekeni nasekuchazeni iziphumo zohlalutyo. Ngokuqhelana neepropathi zabo, izicelo, kunye nokuqwalaselwa Unokuphucula ukhetho lokuphucula ii-chromatographics zokuphucula amanqanaba aphezulu kunye nokuxhasa amanqanaba aphezulu kunye nokuxhasa amanqanaba e-bietechnology kumda oqhelekileyo; Ukukhetha izinto ezisebenzayo ze-Septa lilitye lesiseko se-chromatography!
