As a single-use filter cartridge, syringe filters are utilized to remove particles from the sample prior to high-performance liquid chromatography (HPLC). The scientists like to attach them to the end of the syringes for general filtration, as syringe filters are affordable and convenient in any lab.
Syringe filter is an important tool to get accurate and reliable results where we have a few particular laboratory procedures. Due to the high pressures and narrow bore that particles contain, syringe filter are a most popular tool to use prior to HPLC analysis, because it is proved that using syringe filter to remove particles will prevent it from causing damage to an HPLC.
The only way that you get the best results is to select a proper syringe filter for your application. When you are going to work with aqueous samples, you’d better choose a syringe with a hydrophilic membrane, such as Nylon, PES, GHP or PVDF membranes which work best. If you are working with gases and organic solvents, hydrophobic membranes, such as PTFE membranes are always the best choices, which can repel water and prevent reacting with aggressive organic solvents.
