Condensation Particle Counters (CPCs) are in situ sensors that measure aerosol particle concentrations. CPCs determine aerosol levels by condensing fluid onto particles, causing them to grow to sizes detectable by optical scattering. Typically, CPCs can detect particles ranging from 7 nm to 3 μm, measure concentrations up to 100,000 particles per cubic centimeter, and provide readings every second. CPCs are manufactured by TSI Incorporated and can be used on airborne, shipborne, and ground-based platforms.

The Two Stage Viable Andersen Cascade Impactor (ACI) is an in situ impactor for aerosol sampling. It is used when the size distribution is not required and only the total particle counts are needed for analysis. The sampled air flows through the instrument, and the aerosol particles are collected on the corresponding plates within 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 has an exact flow rate of 28.3 liters per minute.
