Los ntawm muaj zog acidic dej rau lipophilic tshuaj, xaiv cov qauv tsis ncaj ncees lawm tuaj yeem sib tsoo rov qab lossis ua rau phantom peaks. Cov lus qhia no tsis sib thooj ntawm cov khoom siv dej qab zib ntawm cov dej qab zib-txiv qaub vs. borosilicies carning kev tso cai rau cov khoom siv-tshem tawm cov khoom siv tau tshwm sim los ntawm cov khoom tsis zoo.

Vial & Septa cov lus pom zoo los ntawm cov qauv

Qauv Hom	Pom zoo vial	Septum Xaiv	Qhov chaw kom tsis txhob
WASTEWATER (PH 1.5)	High-borosilicate ntshiab ntshiab	Dawb PTFE \ / Silicone Composite	Tsis Txhob Siv Dej-Txiv Qaub (Dissolves hauv 24 H)
Tshuaj impurities hauv acetonitrile	Nruab nrab-borosilate vial	Xiav ntshiab PTFE	Tsawg-borosilate ua rau peak tninging
Cov zaub roj yuav khoom	Amber High-borosilicate	Ua ntej-qhab nia silicone	Ntshiab iav yuav tsum muaj kev tiv thaiv lub teeb
Qhia cov buffers (nruab nrab)	Dej qab zib-kua quav iav vial	TXAWV Silicone	Tsuas yog rau lub sijhawm luv luv, nruab nrab ntawm cov qauv

Kev Kawm Kev Kawm: Txoj Kev Hloov Hloov Ua Haujlwm hauv Pharma

Thawj teeb tsa:
- Qauv: API hauv 0.1% formic acid \ / acetonitrile (1: 1)
- Thawv: Tsawg-borosilissate vial + txheem Silicone Septum
Teeb Meem:
- Tsis paub txog peaks tau tshwm sim ntawm kev txhaj tshuaj # 3 (silicone leacreas)
- API cov ntsiab lus poob los ntawm 12% tom qab 72 h (iav adsorption)
Kev daws:
- Txhim kho rau nruab nrab-borosilicate hydrolytic iav vials
- Hloov mus rau tuab PTFE \ / Silicone composite septa (ua ntej patced 5 ×)
Qhov tshwm sim:
- Phantom peaks tshem tawm
- Kev ntsuas kev ruaj khov txawv <5%
