Sprays & Foams

A spray is a dynamic collection of drops dispersed in a gas. The process of forming a spray is known as atomization. A foam is a substance that is formed by trapping pockets of gas in a liquid or solid. A bath sponge and the head on a glass of beer are examples of foams. In most foams, the volume of gas is large, with thin films of liquid or solid separating the regions of gas.

Our instruments can measure the following properties of sprays and foams:

  • Particle size
  • Time resolved particle size (sprays)
  • Texture and rheological properties (foams)
  • Physical stability (foams)
  • Color (foams)
