Thermo Two Stage Viable Andersen Cascade Impactor. smaller particles are inertial impacted on the agar plate. e. viable particles are retained on the agar plate and the exhaust air is carried andersen cascade impactor (aci) is a multiorifice impactor for use when sampling stages and a base plate that is based on the inertial impaction.
Impactors were first developed in the 1860s for collecting dust and airborne particulates since then there has been numerous advances in the field with the first cascade impactor (May Cascade Impactor) being developed in 1945 for military applications. In the 1950s the Andersen Cascade Impactor also known as an ACI was first developed.
