Water and acetonitrile were passed through polypropylene or PTFE syringe filters (as indicated in legend), then used 1:1 (v/v) to prepare the mobile phase for UHPLC. The system was run at 0.25 mL/min for 600 min with backpressure recorded every 50 min. DP represents total change in backpressure after 600 min.

Description. Millex™-LG, LCR filters contain hydrophilic PTFE membranes and are HPLC-certified. for low levels of UV-absorbing extractables. Hydrophilic PTFE membranes have broad chemical compatibility, enabling filtration of aqueous and organic solvents. 33 mm hydrophilic PTFE Millex™ filters have faster flow rates than 25 mm filters.

Hydrophilic PTFE membranes are ideal for preparing samples and mobile phases prior to liquid chromatography (LC) or mass spectrometry (MS) analysis and can be used to filter aqueous solutions without prior wetting. Syringe filters are available in two pore sizes and three diameters to optimize results.
