Understanding cascade impaction and its importance for inhaler testing Page 3 of 6 Figure 2: Collection efficiency curve for a cascade impactor stage As nozzle size decreases, velocity increases, allowing the collection of increasingly small The Andersen Cascade Impactor (ACI) is arguably the most commonly used impactor within the pharmaceutical industry for the testing of inhaled products. The ACI is an 8stage cascade impactor suitable for measuring the aerodynamic particle size distribution (APSD) of both MDIs and DPIs.
Sample wet or dry particulates with the Thermo Scientific EightStage NonViable Andersen Cascade Impactor. First in its class, the impactor is the original design cited as the world's reference for aerosol particle sizing.
The impactors are uniquely defined as a primary standard classification Impactor Vision Inspection System (IVIS) Overview. The Impactor Vision Inspection System (IVIS) has been specifically designed by Westech in conjunction with Specac Ltd, Uk, to measure with a high degree of certainty the significant parameters relating to the size and shape of the jets on each of the stages of Westech Andersen cascade impactor manual lawn NonViable Impactors or AndersenAndersentype impactors.
