Syringe Filters for HPLC and sample preparation

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

HPLC Troubleshooting Filtration - Crawford Scientific

As an example, a typical HPLC column may have particle sizes of 5 µm and, therefore, a frit of 2 µm, which will become blocked very quickly. Table 1 gives an overview of some of the techniques to consider when selecting a suitable filtration method. Syringe filters are the most common and cost-effective method of filtering samples for HPLC.

Syringe Filter Efficiency on HPLC Column Life - Merane

It is the intent of this work to demonstrate that filter efficiency must be considered when choosing an HPLC sample-prep filter and that filtration will lengthen the life of a column. In this paper, retention efficiency of three effectively equivalent 0.45 µm rated syringe filters was examined using 0.45 µm average diameter latex spheres.

How to Select a Syringe Filter and How to Use it? (2020 Guide)

A syringe filter (sometimes called a wheel filter for its wheel-like shape) is a single-use merane based filter cartridge, to be attached with a syringe to remove impurities in liquid solutions. This pre-filtration step is vital in preventing damage to instruments (e.g. liquid chromatography, ICP, etc.).
