Equipment

A known volume of an emulsion containing particles, whose size distribution is to be determined, is placed in a glass chamber pressurized by air. The emulsion is then directed through a sip pipe, where it flows through a sensor that counts the particles. The sensor sends an analog signal to the electronics box, which converts it to a digital signal and provides the particle distribution curves. There are two sensors available, depending on the particle size.

A slurry of particles in deionized (DI) water is first prepared. The device uses a sensor to count the particles as the emulsion flows through it to produce particle distribution curves.
