概要（Overview）

A COULTER LS Series instrument, Figure 1.1, measures the size distributions of particles. An instrument with a Fluid Module, Hazardous Fluids Module, or Micro Volume Module can measure sample particles suspended in a liquid. An instrument with a Dry Powder Module can measure sample particles suspended in air. The LS230 measures particles from 0.04 μm to 2000 μm.
