Septa ua lub luag haujlwm tseem ceeb hauv chromatography pectalyzes, ua raws li kev txwv ntawm cov qauv kev paug, evaporation thiab tswj kev ncaj ncees thaum ntsuas kev txheeb xyuas.Ntau hom ntawm septaMuaj - ob feem ntau siv pawg tau sib khi ua qhev thiab kev nkag siab zoo rau cov septica rau kev txheeb xyuas qhov tseeb yog qhov tseem ceeb los xyuas kom meej.

Kev txhais thiab lub hom phiaj ntawm septa

Ib qho septa yog nyias, yoog raws disc, feem ntau yog ua los ntawm cov khoom xws li Silicone lossis roj hmab, uas tau muab tso rau hauv lub hau ntawm lub qab. Lawv lub luag haujlwm tseem ceeb yog los tsim lub cev tsoos airtight uas tiv thaiv kev ua paug, kev paug, thiab kev poob ntawm kev txhaj tshuaj thaum lub sij hawm txhaj thiab cia. Qhov kev sib tw no tso cai rau cov phom rab koob tso rau thaum tswj cov qauv kev ncaj ncees. Xaiv cov septum tsim nyog rau kev ua tau zoo chromatography ua tau raws li nws ncaj ncaj cuam tshuam ncaj qha cuam tshuam cov qauv kev ncaj ncees thiab cov ntaub ntawv raug.

Sibred Septa:

Sib khi lus sertayog txawv los ntawm ib txheej ntawm silicone txuas kealusing rau lawv cov npoo, feem ntau muaj roj hmab hluav taws xob. Tshuaj lom neeg thev naus laus zis sib txuas hom no Silicone Faib ncaj qha rau cov khoom siv Sepicone ntau thaum txo qis kev ua kom ntshav lossis kev sib cav uas tuaj yeem ua rau cov txiaj ntsig chromatographic. Qhov txheej txheem sib raug zoo no txhim kho lub durability thiab kev ruaj khov ntawm lub septum, kom nws muaj kev nyab xeeb thaum lub sijhawm txhaj tshuaj. Cov ntawv muaj kev ruaj ntseg tsim los ntawm kev sib raug zoo saiv sauv sauvta minimizes kev pheej hmoo ntawm kev tsiv teb tsaws, ua kom haum rau cov ntawv thov HIGPRAPS.

Thaum lawv zoo li yuav tau them tus nqi ntau dua, lawv yuav nthuav qhia kev ua tau zoo thiab xwm txheej vim tsis muaj ib txheej sib khi ua los ua kev txhawb nqa. Tsis-sib khi lus septa tau yooj yim rau nruab thiab tshem tawm, tab sis lawv yooj yim yuav ua rau muaj teeb meem xws li kev hloov pauv thaum siv kev ua tiav ntawm cov qauv.

Los ntshav:

A key distinction between bonded and non-bonded septa is silicone bleeding, or release of silicone molecules from septa into samples that interferes with analyses. Chemically sib khi Silicone txheej rausib khi lus sertatuaj yeem txo qhov teeb meem no tau, txiav txim rau sepruaa ntau haum thaum muaj cov qauv uas yuav muaj cov hnoos qeev txawm tias muaj ntau cov hnoos.

Precision thiab qhov tseeb:

Sib koom ua ke sterta muab cov qauv kev ncaj ncees los ntawm kev txwv kev ua tau zoo, ua rau lawv pom zoo tshaj plaws uas yuav tsum tau ntsuas qhov kev txiav txim siab.

Daim ntawv thov tau:

Sib koom ua ke septa yog qhov zoo rau siv nyob rau hauv ntau hom kev ntsuas tshuaj, suav nrog roj chromatography (GC) thiab kua chromatography (LC). Lawv cov versatility ua rau lawv tshwj xeeb haum rau volatile lossis semivolatile sib txuas, pab tswj cov chaw ruaj ntseg, pab saib xyuas kev ruaj ntseg thaum tseem tiv thaiv kev soj ntsuam los ntawm kev ploj.
