Septa xaiv rau autosampler vials

Lub septum koj xaiv rau kojAutosampler VialYuav cuam tshuam cov qauv evaporation, piv cov qauv kev ruaj ntseg, koob khoov thiab thaiv, thiab cov ntsuas downtime. Tsis txhob cia qhov nyuaj ntawm senta xaiv qeeb koj qis.

Septa xaiv cov cuab tam

Lub supta xaiv cov cuab yeej pom zoo septa zoo tshaj plaws los ntawm teb ob peb cov lus nug yooj yim, xws li:

1. HPLC, UPPC, lossis GC?

2. Ntsia thawv cov kaus mom, Crimp lub kaus mom saum, thiab Snap-nws kaus mom?

3. Autosamper koob hom & lub taub taub?

4. Kev Txiav Txim lossis Tsis-Txiav Txim?

5. Kev rov qab muaj peev xwm?

6. Cov kuab tshuaj thiab qhov kub uas lub septa yuav raug rau?

7. Ntau cov kev txhaj tshuaj?

SEARA TRENEAR LOJ

SEPTA xaiv cov cuab yeej ua rau siv daim duab hauv qab no los xaiv ib qho septum uas yuav pab tiv thaiv kev ua paug thiab zam kev puas tsuaj.

Ob lub ntsiab lus tseem ceeb koj yuav tsum xav txog thaum xaiv lubTsim nyog Septa:

1. Ntsuas

Txhua lub twj paj nruag siv cov khoom sib txawv ntawm cov khoom sib txawv thiab rau qee yam khoom siv nrog tus nqi qis dua (Hardness) tus nqi yuav pab txo cov teeb meem ntawm rab koob, xws li txoj kev siv sia.

2. Cov lus sib txuas ntawm kev txaus siab

Yog tias koj cov lus teb yog qhov tsis sib xws ces xaiv septa uas yuav muab lub foob kaw ntom khwm yog qhov tseem ceeb rau kev tiv thaiv kev ploj. Peb lub zog kaw ntom nti (Avcs) tshem tawm cov lus hauv kev ua tiav ntawm kev ua kom zoo tshaj plaws thaum kaw lub vial.

3. Cov kuab tshuaj

Qee cov kuab tshuaj uas feem ntau siv rau HPLC, UPPC, thiab GC cov kev sim tuaj yeem cuam tshuam senma kev ntseeg ncaj ncees.

4. Kub

Yog tias koj xav tso cov qauv vial nyob rau hauv kev kub siab ib puag ncig, koj yuav tsum xav txiav txim siab savta cov khoom uas tuaj yeem tiv thaiv cov soons uas tuaj yeem tiv taus cov khoom kub siab.

Septa cov ntaub ntawvCov Khoom Siv

Septa yog tsim los ntawm cov khoom sib txawv. Saib hauv qab no rau cov ntsiab lus txhais thiab siv ntau hom ntawm septa cov ntaub ntawv.

Silicone Roj Hmab Septa

Zoo siab, silicone yas roj hmab laminated rau PTFE. Siv thaum zoo tshaj plaws kev rov qab zoo tshaj plaws yog qhov yuav tsum tau ua. Septum tiv thaiv kev sib nraus thiab raug pom zoo thaum muaj kev txhaj tshuaj ntau. Xav txog sterra rau kev siv hauv cov kua chromatography daim ntawv thov.

PTFE \ / silicone: ib qho muag muag muag muag heev li ptfe. Septum tiv thaiv kev coring thiab yog pom zoo rau cov twj nrog cov koob txhaj tshuaj haum zoo. Kuj pom zoo rau LC-MS thiab GC-MS vim muaj siab huv.

PTFE \ / ptfone \ / ptfe: ib txheej ntawm PTFE ntawm txhua sab ntawm cov nruab nrab nyuaj silicone. Feem ntau tiv taus coring nrog saum-nruab nrab rov qab cov yam ntxwv. Pom zoo rau feem ntau xav tau cov ntawv thov xws li kev saib xyuas kev ntsuas, lub sijhawm ntev dua ntawm kev txhaj tshuaj, lossis cov qauv hauv sab hauv. Siv ib qho autosampler siv cov kab uas loj loj, blunt-ntsis koob txhaj tshuaj.

Pre-sluit PTFE \ / Silicone: Pre-sluit, zoo-zoo ntshiab ntshiab silicone faced nrog PTFE. Rau cov ntawv thov siv lub ntsej muag zoo heev
