NGI and NGI Plus

The Next Generation Impactors (NGI) from MSP, a Division of TSI®, are high-performance cascade impactors with seven stages.

The NGI is and has been the industry standard pharmaceutical cascade impactor for the last 20 years, with 1800+ units in use and adopted into the USP guidelines. It was designed and developed by and for the OINDP Industry, and is the most efficient and accurate way to do standard in vitro APSD testing. There are many automated and semi-automated add-ons as well as other accessories designed to further improve efficiency.

The newer NGI+ uses the same industry proven design and substitutes materials to enable a wider range of applications, chemicals, and drugs.
