A modular tool for analyzing cascade impactors data to improve exposure assessment to airborne nanomaterials

This work aim was to develop a modular programme allowing the inversion of data stemming from cascade impactors based on the mass (or any quantity) collected on each impaction stage. Through a precise description of the collection efficiency curves of the different stages, the software provides a continuous curve (from 100 to 1000 points) using the Markowski method, and An additional option consists in determining the experimental error at each point of the inverse curve, performed by realizing several consecutive inversions.
The inversion procedure was first tested and optimized for the case of the Sioutas personal sampler. Validation of the calculation was performed considering theoretical aerosols.
