Cytiva's Whatman GD/XP disposable syringe filter, a modification of the GD/X line, uses a polypropylene prefilter stack, making GD/XP suitable for samples that require inorganic ion analysis. Incorporates a two-layer polypropylene prefilter stack rather than a multi-layer glass fiber stack to minimize levels of ion extractables Extremely low protein binding syringe filter High loading volume for filtration of challenging samples Recyclable after use. Learn how you can recycle it. Disposable syringe filter for trace metal analysis Because of their high purity and minimal ion extractables, GD/XP syringe filters are recommended for analyzing 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). GD/XP syringe filter with integrated prefilter The Whatman GD/XP disposable syringe filter from Cytiva's business has several different membrane material options. These include: Nylon Polyvinylidene difluoride (PVDF) Polytetrafluoroethylene (PTFE) Polypropylene – membrane or depth filter media Polyethersulfone (PES)
