How to Choose Right Syringe Filter -- Filter Membrane Materials
PTFE membranes are chemically resistant to nearly all solvents, acids and bases. The membrane has low extractable and good thermal stability. PTFE is hydrophobic and requires pre-wetting prior to use with aqueous solvents. Membrane: HPLC certified PTFE, with polypropylene support; Use with: Aggressive solvents, strong acids, alcohols, bases
Syringe Filter(PTFE) - Quzhou Lab Technology Co.,Ltd,hplc
Syringe Filter(PTFE) A syringe filter (sometimes called a wheel filter if it has a wheel-like shape) is a single-use filter cartridge. It is attached to the end of a syringe for use. Syringe filters may have Luer lock fittings, though not universally so. The use of a needle is optional; where desired it may be fitted to the end of the syringe

Filters are packaged into separate tubes to protect them from external sources of extractables. While one tube is in use, the others are kept sealed. Excellent chemical resistance. Use this universal filter for all your LC-MS samples. The WWPTFE (water wettable polytetrafluoroethylene) membrane can be used with both organic and aqueous solvents.

Syringe Filters for HPLC and sample preparation | analytics
Pore Sizes and Pore Volumes. The filter size depends highly on the filtration volume. For small volumes (< 1 ml), syringe filters with a diameter of 3 mm are usually for medium volumes (1-10 ml), 15 mm and for large volumes (> 10 ml) 25 mm. Common pore sizes for UHPLC and HPLC columns with small particle sizes (< 3 µm) are 0.2 and for columns with larger particle sizes (> 3.5 µm) 0.45 µm
Importance of Sample Filtration in Liquid Chromatographic
Nov 13, 2013 · Teflon filters are useful for organic solvents. Nylon filters can be used for both aqueous as well as organic samples but acidic samples should be filtered using PTFE-based membrane filters. It goes without saying that the objective of sample filtration would get defeated if the mobile phase itself is not filtered.

HPLC Troubleshooting Filtration - Crawford Scientific
Not choosing the correct filter membrane is a common problem that creates issues in HPLC; such as the introduction of extraneous extractables and reducing the detection of analytes. Furthermore, solvents that are incompatible can cause swelling of the filter polymeric material which will affect performance and filtration efficiency.
