  • What is nonionic polyacrylamide (NPAM)?
  • Nonionic Polyacrylamide (NPAM): NPAM is a high-molecular-weight polymer or polyelectrolyte with polar groups that enable it to adsorb suspended solid particles in water, forming larger flocs. It accelerates particle settling in suspensions, resulting in improved solution clarity and enhanced filtration.
  • What is a polyacrylamide gel?
  • Polyacrylamide gels are three-dimensional networks of acrylamide reacted with the bifunctional reagent N,N '-methylene-bis-acrylamide (abbreviated as Bis) via a free-radical initiated vinyl polymerization mechanism. The pore size of the gel is very reproducible and is directly related to the ratio of acrylamide to Bis.
  • What is cationic polyacrylamide (CPAM)?
  • Cationic Polyacrylamide (CPAM): CPAM is a linear high-molecular-weight compound known for its affinity and adsorption capabilities due to its active functional groups. It is primarily used for coagulating colloids with negative charges.
  • Are polyacrylamide gels homogeneous?
  • Polyacrylamide gels have the great advantage of being almost completely homogeneous, and adsorption and electro-osmosis do not play a major role in the electrophoresis (see e.g. Maurer, 1971).
