Choose the compatible filter referring the following chart. Polytetrafluorethylene. If the membrane dissolves in the filtration process, that membrane will be totally useless in filtering those solvents. This chart outlines the chemical compatibility of the most common syringe filters. Related. Chemical compatibility is a critical consideration when selecting the proper sample prep syringe filter for your application. Polytetrafluoroethylene (PTFE), polyvinylidene difluoride (PVDF), and regenerated cellulose (RC) membranes are popular choices, because they are highly compatible with common mobile phase solvents such as purified water, acetonitrile, and methanol.
