    AMMONIUM SULFATE CRYSTALLIZATION IN ANDERSEN

    The Andersen sampler (Model 0203) modified by the addition of a seventh impaction stage was used to coilect and separate airborne particles according to their sizes. During sampling, the sampler was covered with an inverted petri dish to prevent rain water or snow from entering into the sampler.

    Performance Evaluation of an Andersen Cascade Impactor

    Andersen cascade impactor using inertial filter technology (ANIF). The sampler consists of an 8-stage impactor from the Andersen cascade impactor (Tokyo dyrec AN-200), and a nozzle section that will smoothly correct the flow from the final impactor stage with a 0.43 μm cutoff size and then introduce the flow to the inertial filter stage.

    Abstract. Meteorologists are accustomed to the atmospheric phase changes of water. It is observed that phase changes ending with crystallization and crystal growth of (NH 4) 2 SO 4 take place in Andersen Samplers used to collect size-stratified samples of airborne particles.
