Mobile phase filtration is performed prior to placing the solvent into the solvent reservoir. Buffered mobile phase solvents require daily filtration with a 0.2 μm filter to eliminate microbial growth that could increase the baseline. The primary concern when choosing a solvent filter is solvent compatibility with the filter material.

Intro. There are so many solvents and syringe filter/membrane materials that it can be tough to remember which combinations are safe and which are corrosive. These tables show five common syringe filter materials -- Cellulose Acetate (CA), Nylon, PES, PTFE, and PVDF -- and their compatibilities with 75 common solvents.
Pall GHP Polypropylene membrane will be discontinued effective October 31st, 2019. This discontinuation affects devices including Centrifugal Devices, Syringe Filters, Filter Plates, and Membrane Filter Discs.
