A new cascade impactor has been designed for the OINDP Industry, specifically for pharmaceutical inhaler testing, and is the most efficient and accurate way to do standard in vitro APSD testing.

The Impactor, called the Next Generation Impactor (NGI), has seven stages and is intended to operate at any inlet flow rate between 15 and 100 L/min.

It offers a cut size (D50) spectrum spanning from 0.98 µm to 14.1 µm aerodynamic diameter at 15 L/min, 0.54 µm to 11.7 µm aerodynamic diameter at 30 L/min, 0.34 µm to 8.06 µm at 60 L/min, and 0.24 µm to 6.12 µm at 100 L/min.

The impactor’s aerodynamics adhere to well-established scientific principles, ensuring reliable particle size fractionation behavior across the designated flow range.
