Hauv cov tshuaj chromatographic, xaiv cov qauv coj ncaj qha cuam tshuam qhov tseeb thiab rov ua dua tshiab ntawm koj cov txiaj ntsig. Kab lus no muab cov qauv sib txawv ntawm qhov sib txawv ntawm HPLC thiab GC coj mus thov cov xwm txheej, thiab kev ua yuam kev yuav tsum tau xaiv thiab ua kom muaj kev tshawb fawb txog kev tshawb fawb.

I. Qhov sib txawv ntawm HPLC thiab GC vials

1. Daim Ntawv Thov Kev Sau Npe

HPLC Vials: Feem ntau yog siv hauv kev ua kom zoo kua chromatography (HPLC) thiab LC-MS Kev Tshawb Xyuas, tsim nyog rau tsis muaj qhov tsis ruaj khov, lossis cov qauv ntsuas teeb pom kev zoo.

Ntsia thawv saum vials

GC Vials: Siv rau hauv cov roj chromatography (GC) thiab GC-MS, xav tau kev tiv thaiv kub ntau (feem ntau yog siv 300 ° C) thiab sib xyaw nrog cov kuab tshuaj uas tsis muaj kuab lom.

2. Cov khoom siv thiab tsim cov yam ntxwv

Vial caj dab hom:

HPLC:Feem ntau siv ntsia hlau saum lossis snap saum, zoo tagnrho rau kev rov nkag mus ntxiv thiab cov qauv pib.

GC:Feem ntau crimp sab saum toj vials nrog txhuas lub hau thiab ptfe \ / silicone sawbera rau kev sib khi ntsuas kub.

Cov khoom siv xaiv:

HPLC:Feem ntau ua los ntawm high-purity borosilicate iav, nrog Amber version rau lub teeb-rhiab kuaj.
GC:Yuav tsum muaj qhov kub-borcase-borosilicate iav yog ib txwm muaj, nrog PFA yas siv nyob rau hauv cov ntawv thov tshwj xeeb.

Ii. Cov kev txiav txim siab tseem ceeb rau cov khoom siv chromatography Vial

1. Cov Khoom Siv Cov Khaub Ncaws

Borosilicate iav: Cov inert thiab cua sov resistant; Haum rau ob qho tib si HPLC thiab GC Kev Ntsuam Xyuas.
Lub pob zeb iav: Muab kev tiv thaiv lub teeb rau lub teeb pom kev zoo.

2. Cov Khoom Siv Yas

Polypropylene (pp): Raug nqi thiab haum rau kev siv tsawg; Tsawg cov kuab tshuaj thiab kub tiv taus.
Perfluoroalkoxy (pfa): Siab thermal kuj thiab cov tshuaj inertness; Qhov zoo tagnrho rau kab thiab kev ntsuas kub gc kev tsom xam.

3. Cap thiab Septa cov ntaub ntawv

PTFE \ / Silicone Septa: Tiv thaiv cov kuab nkag rau hauv HPLC; ceev cov duab nyob rau hauv gc.
Cov hau kev sib khi: GC lub kaus mom Crimp yuav tsum muaj cov cuab yeej tshwj xeeb, thaum HPLC ntsia hlau lub kaus mom yog yooj yim dua.

III. Kev sib raug zoo thiab yuav ua li cas kom zam lawv

1. Ntsuas hloov tau

Autosampler Compatibility: Xyuas kom cov vial lub qhov siab thiab txoj kab uas hla kev txiav (piv txwv li, 2 ml cov qauv vials).
Sauda puncture tiv taus: Rau kev txhaj tshuaj nquag hauv HPLC, xaiv SEPCC, xaiv sepla nrog siab elasticity (piv txwv li, ptfe \ / silicone puas).

Tig lub vial kaus mom thiab septa, koj yuav tsum paub CLEAK NO

2. Kev tswj kev pheej hmoo pheej hmoo

Zam kev rho tawm: Rau cov gc high-kub gc, xaiv inert iav lossis pfa vials.
Tiv thaiv kev hla kev sib kis: Siv ntawv pov thawj ua ntej lub vials ua ntej (E.g., USP chav kawm a).

IV. Kev yuav Lus Qhia: Xaiv txoj cai vial rau HPLC thiab GC

Txhais cov kev xav tau kev sim: Xav txog qhov ntsuas kub, qauv hloov kho yog muaj kev sib xyaw ua ke, thiab ua haujlwm txhaj tshuaj.
Phim cov khoom sib tw: Ua kom cov hom caj dab zoo, ntim, thiab autosampler sib xyaw.

Xa mus rau cov qauv kev lag luam: Siv vials nrog USP lossis ISO cov ntawv pov thawj rau qhov ua tau zoo sib xws.
Kev Ntsuas Cov Nqi Them Nqi: Rau cov kev sim nquag, xaiv cov iav vials; rau kev txiav nyiaj tawm, xaiv rau cov khoom siv inert.

V. FAQ - Cov lus nug ib txwm tau teb

Q: HPLC vials yuav siv rau GC kev tsom xam?
A: Yog tias ua los ntawm borosilicate iav thiab cua sov resistant (E.g., txog li 400 ° C), tej zaum lawv yuav raug siv ib ntus. Txawm li cas los xij, kev siv sijhawm ntev nyob rau hauv kev kub siab tsis pom zoo.

Q: Yuav ua li cas kom tsis txhob kis phem?
A: Xaiv cov vials ua ntej ntxuav lossis huv lawv chaw nres tsheb hluav taws xob siv chromatographic-cov kuab tshuaj.

Q: yog crimp-sab saum toj vials tsim nyog rau gc?
A: Crimp vials muab cov kev sib khi zoo dua thaum muaj kev txhawb nqa ntsia hlau kub, txawm hais tias qee cov seev txhawb ntsia hlau hau nrog cov khoom siv.
