  • What is nonionic polyacrylamide (NPAM) gel?
  • Nonionic polyacrylamide (NPAM) gel was prepared for in-depth profile control. A compact three dimensional network structure was formed in the bulk gel system. Retention, adsorption and bridging across the pore throats occur in high permeability zones. The NPAM gel shows superior high temperature resistant. °C.
  • How are polyacrylamide gels prepared?
  • Polyacrylamide gels are prepared by free radical polymerization of acrylamide and a comonomer crosslinker such as bis-acrylamide. Polymerization is initiated by ammonium persulfate (APS) with tetramethylethylenediamine (TEMED) as the catalyst (see figure below).
  • What is immobilization in polyacrylamide gel?
  • Immobilization in polyacrylamide gel is a technique based on the polymerization of acrylamide with N,N′-methylene-bis-acrylamide (Bis) as the cross-linking agent. The degree of cross-linking is controlled by adjusting the ratio of acrylamide to Bis used. Being nonionic in nature, polyacrylamide is the most widely used matrix for entrapping enzymes.
  • What does %t mean in polyacrylamide gel?
  • %T indicates the relative pore size of the resulting polyacrylamide gel: higher %T refers to a larger polymer-to-water ratio and on average smaller pores. The practical ranges for monomer concentration are stock solutions of 30-40%, with different ratios of acrylamide monomer to crosslinker.
