NGI and NGI Plus

The Next Generation Impactor (NGI) from MSP, a Division of TSI®, is a high-performance cascade impactor with seven stages.

It 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.

Related Accessory

The NGI Cooler™ is an important accessory for the NGI/NGI+, designed to counteract the the evaporation problems caused by retained heat due to the thermal mass of the NGI. The cooler is required for nebulizers per USP testing and also recommended for particular mist inhalers as it prevents the droplet size from changing due to evaporation, maintaining the integrity of the Aerodynamic Particle Size Distribution (APSD) data for accurate measurements.

Service & Calibration

Mensuration and calibration are imperative in pharmaceutical testing, and is recommended by the FDA (Food and Drug Administration), USP (United States Pharmacopeia), and GMP (Good Manufacturing Practices).

MSP provides calibration and mensuration services, as well as calibration contracts and extended warranties as part of our QualityGuard™ program.
