Yuav ua li cas xaiv HPLC Vial senta rau koj cov kuab tshuaj
Yam los txiav txim siab thaum xaiv HPLC Vial sentera
1. Tshuaj Zoo
Thawj qhov uas yuav tsum xav txog yog cov tshuaj sib xyaw ua ke ntawm cov khoom siv septum nrog cov kuab tshuaj koj npaj siv. Cov ntaub ntawv sib txawv muaj cov tshuaj tiv thaiv txawv rau cov tshuaj:
PTFE (Polytetrafluoroethylene): PTFE paub txog nws cov tshuaj lom neeg ua tau zoo thiab yog qhov haum rau ntau hom kuab tshuaj, suav nrog cov tshuaj corrosive. Nws feem ntau yog siv hauv kev sib xyaw nrog lwm cov ntaub ntawv.
Silicone: Silicone Sepico yog hloov tau thiab tuaj yeem rov qab tau tom qab rab koob nkag mus, ua rau lawv haum rau kev txo cov tshuaj. Txawm li cas los xij, lawv yuav tsis sib haum nrog txhua cov kuab tshuaj.
Butyl Roj Hmab: Cov khoom no muaj kev sib khi zoo, tab sis muaj cov tshuaj tiv thaiv kev tiv thaiv rau PTFE.
PTFE \ / Silicone Composite: ua ke cov txiaj ntsig ntawm ob cov ntaub ntawv, nrog tshuaj lom neeg zoo thiab rov ua dua.
2. Cov Hom Hom
Hom tshuaj siv yuav cuam tshuam rau kev xaiv Septum:
Cov tshuaj aqueous: rau cov kuab tshuaj-silicone, silicone lossis ptfe \ / Silicone sitta feem ntau pom zoo vim lawv zoo heev.
Organic cov kuab tshuaj: rau cov kuab tshuaj organic xws li Methanol lossis Acetoniturile, PTFE lossis PTFE lossis PTFE COMPOSites yog nyiam vim lawv cov tshuaj tiv thaiv zoo heev.
Corrosive tshuaj: rau cov kuab tshuaj muaj zog xws li muaj zog acids lossis hauv paus, PTFE feem ntau yog qhov kev xaiv zoo tshaj plaws.
3. Kev Ua Lag Luam
Lub peev xwm ntawm septum los pib tom qab rab koob puncture yog qhov tseem ceeb kom ua qauv ncaj qha:
Slit vs. Cov qauv kev tsis sib tw: qee qhov septa muaj kev sib tsoo kom pab txhawb koob ntxig, tab sis qhov no yuav cuam tshuam rau lub foob nyob rau lub sijhawm. Cov qauv tsis-hlais muab cov foob tig rov qab tab sis tej zaum yuav tsum tau quab yuam ntau dua thaum txhaj tshuaj.
Rov qab pib: Saib rau septa uas tuaj yeem rov qab zoo dua tom qab ntau rab koob kom tiv thaiv kev sib kis thiab evaporation.
Xav paub seb puas yuav xaiv septa nyob rau hauv pre-slit lossis tsis? Thov kos kab lus no: Yuav ua li cas xaiv Septa Pre-Slit lossis tsis?
4. Extractables thiab ntshagables
Thaum ua haujlwm nrog cov qauv rhiab, nws yog qhov tseem ceeb rau kev txiav txim siab cov extractables thiab leachables hauv cov khoom siv septum:
Tsawg Extractables: Xaiv Septa nrog cov khoom siv qis qis los txo qhov kev pheej hmoo ntawm kev paug. PTFE muaj cov khoom siv tsawg dua piv rau cov khoom siv roj hmab-burter.
Cov qauv xeem: Qee cov tuam ntxhab muab cov ntaub ntawv ntawm cov extractables; Txheeb xyuas cov specifications no thaum xaiv septum.
5. Kev kub siab kuj tsis kam
Xav txog qhov ntsuas kub uas koj lub zog HPLC yuav ua haujlwm:
Kev kub siab: Yog tias koj daim ntawv thov cuam tshuam nrog kev kub siab, nco ntsoov cov khoom siv septum tuaj yeem tiv thaiv cov mob no yam tsis muaj kev ua tsis txaus ntshai.
Cryogenic daim ntawv thov: rau cov ntawv thov cryogenic, xaiv cov khoom uas tswj hwm kev ncaj ncees ntawm qhov kub tsawg.
6. Lub cev muaj zog
Cov yam ntxwv ntawm lub cev kuj tseem yuav cuam tshuam kev ua tau zoo:
Thickness: Thicker septa yuav muab lub foob zoo dua tab sis yuav xav tau ntau zog rau lub zog kev nkag mus.
Cov khoom siv tawv tawv: Cov ntaub ntawv softer yuav muab cov khoom rov qab zoo dua tab sis yuav raug rau kev raug mob ntau dua thaum siv tas.
