Syringe Filters for Ion Chromatography - Support

With ion chromatography, the type or chemistry of the solution being filtered through the syringe filter will impact its merane material. This should be taken into consideration when deciding which syringe filter material to use. For example, some syringe filter merane

Merane Filter - an overview | ScienceDirect Topics

The MF test is easier to perform than the MPN test because it requires fewer test tubes and less handling. Usually about 100 ml of water is passed through a merane filter (pore size 0.45 µm). This merane is then placed on a thin, absorbent pad saturated with differential or selective medium (Figure 17.2).For example, if total coliform organisms are sought, a modified Endo medium is used.

Merane Type (PTFE, wwPTFE, PVDF, Nylon) — Typically, the first step in selecting a suitable filter is to choose a merane that is chemically compatible with the sample (see chart). For aqueous samples, it is preferable to use a hydrophilic merane (wwPTFE, PVDF, or Nylon) versus a hydrophobic merane (PTFE).
