These syringe filters, with pigment-free PP housing, are ideal for use with samples that require inorganic ion analysis, as levels of ion extractables are minimised.

• Extremely low protein binding
• Contain a two-layer pre-filter stack comprising of 20 and 5 µm PP filters, with a choice of membranes
• High loading volume for filtration of challenging samples
• Flow should enter from the inlet

Because of their high purity and minimal ion extractables, GD/XP syringe filters are recommended for analysing ion content that would otherwise experience interference from glass-based extractables. For example, GD/XP is used for trace metal analysis, particularly ion analysis using inductively-coupled plasma-mass spectrometry (ICP-MS).
