When using electrochemical detection, spurious peaks in your chromatogram may be observed if a nylon syringe filter is used with a DI water solvent. The anionic peaks are most likely nitrate extractable and therefore we recommend using polyester sulfone PES syringe filters instead. This membrane type is suited to situations when you want to avoid nitrate extractables. Click HERE for PES syringe filter ordering information and pictures.
If anions are not a concern, nylon filters are adequate for aqueous solvents with electrochemical detection.
