The Two-Stage Viable Andersen Cascade Impactor (ACI) is an in situ aerosol sampler. It is used when only the total particle count is needed for analysis and the size distribution is not required. The sampled air flows through the instrument, and aerosol particles are collected on the corresponding plates in the two sampling stages. Larger particles (> 8 μm) are collected in the first stage, while smaller particles (0.8-8 μm) are collected in the second stage. It maintains a precise flow rate of 28.3 liters per minute.
