Incorporates a twolayer polypropylene prefilter stack rather than a multilayer glass fiber stack to minimize levels of ion extractables Extremely low protein binding syringe filter High loading volume for filtration of challenging samples 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. 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 glassbased extractables. For example, GD/XP is used for trace metal analysis, particularly ion analysis using inductively coupled plasmamass spectrometry (ICPMS). 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)
