Answer:No. Crosslinked PVPP is insoluble and acts as a particulate adsorbent rather than a soluble viscosity modifier.
Answer:The typical particle size is approximately 110 µm, and the pack contains 500 g.
Answer:It can adsorb selected phenolic compounds and help clarify complex samples before subsequent analysis or processing.
Supelco Poly(vinylpolypyrrolidone) (PVPP) is an insoluble, crosslinked polyvinylpyrrolidone sorbent with a typical particle size near 110 µm. The 500 g pack supports laboratory-scale clarification and adsorption workflows, especially those involving polyphenol-rich food and beverage samples. Unlike soluble linear polyvinylpyrrolidone, PVPP remains as a particulate adsorbent and can be separated from treated liquids by appropriate filtration or settling methods. Its affinity for phenolic compounds supports reduction of polyphenol-related interference in selected sample-preparation procedures. The material is supplied as solid lumps and should be dispersed with consideration for wetting, contact time and particle removal after treatment. Adsorption efficiency depends on sample composition, pH, sorbent loading and agitation. PVPP is not an analytical reference standard or membrane filter; its main role is selective adsorption and clarification within a validated or experimentally optimized workflow.
