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.

Hydrophobic PTFE membrane filter is made of polytetrafluoroethylene ultrafine fibers by hot-melt bonding together. Difference from glass fiber membrane, PTFE filter is a kind of membrane material for deep filtration. Membrane filter disc has the following characteristics: membrane filter 0.22 μm is produced from food-grade isotactic polypropylene.

Hydrophilic nylon membrane has excellent chemical compatibility with esters, bases, and alcohols and does not require prewetting. GHP (hydrophilic polypropylene) membrane is low protein binding. Both nylon and GHP membrane filters include a glass fiber prefilter layer, as well as being HPLC certified for low UV-absorbing extractables.
In rare cases, a solvent might partly or fully dissolve the membrane, resulting in breakthrough and potential contamination of the sample. Aqueous samples are unlikely to damage most membrane materials, particularly hydrophilic. However, pH is a significant factor in determining membrane compatibility.
