Cascade Impactors Mensuration

Introduction To Mensuration
The Cascade Impactors performance depends on the jet dimensions, the spatial arrangement of the jet , its collection surface and the rate of airflow passing through it. These factors may affect the performance of the Impactors hence proper measurement is necessary as per the compliance with USP and EP.
The process of measuring the nozzle diameters and other critical dimensions of Cascade Impactors is called as Mensuration.
Both European and US Pharmacopoeia recommends stage mensuration of Impactors prior to use and periodically thereafter.
