  "term": "Cascade impactor",
  "field": "Meteorology and atmospheric science",
  "definition": "An instrument that samples and separates airborne particles into different size fractions based on their inertia. The air sample is drawn through a series of stages, each containing nozzles and a collection plate; progressively smaller and lighter particles are impacted onto plates at successive stages with higher air velocities. This device provides a size-segregated distribution of aerosols for mass or chemical analysis.",
