syringe filter membrane

[jiangds06]

how do I choose syringe filter in order to minimize adsorption of hydrophobic analytes in aqueous phase? nylon? PTFE? GSH? cellulose?

[unmgvar]

the way we do it is to try them all.
and compare it to a sample solution that has been centrifuged at high RPMs from which you have injected the supernatant solution
any column can take a few injections of this, even UHPLC. and in most cases 1 is sufficient

Essentially, I follow the same technique. However, if I am unfamiliar with the class of analytes / matrix, then I will also refer to different vendor websites for syringe filter selection and technical support.
