Processing Impactor Data using CITDAS V3.10

CITDAS allows standardized data processing for the operating conditions of four alternative impactors; Andersen Cascade Impactor (ACI), Multi-Stage Liquid Impinger (MSLI), Marple-Miller Impactor (MMI) and the Next Generation Impactor (NGI). The latest release, CITDAS V3.10, accurately reports the MMAD, GSD and up to five FPD groups defined by either Impactor stage or aerodynamic particle diameter. This paper presents the performance of the software for a variety of challenging input distributions and highlights the ability of CITDAS to appropriately report results or identify limits of detection accordingly.
