Colloids & Gels

A colloid is a mixture in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance. The words suspension and emulsions indicates colloids with larger particle size. A gel is a solid jelly-like material that can have properties ranging from soft and weak to hard and tough. Gels are defined as a substantially dilute cross-linked system, which exhibits no flow when in the steady-state.

Our instruments can measure the following properties of colloids and gels:

  • Paticle size
  • Particle structure and morphology
  • Flow properties – rheology
  • Texture
  • Physical stability
  • Particle charge – zetapotential
  • Color
