Next Generation Impactor NGI System
The Inhalation Formulation Fine Particle Aerodynamic Characterization System is specifically designed for testing inhalation formulations. It complies with the instrument requirements of the USP, EP, and ChP (2020 edition) methods for aerodynamic particle size determination of inhalation formulations. This configuration enables testing of inhalation aerosols, including fine particle aerodynamic characterization, delivered dose uniformity, and other pharmacopeial-required tests.
Application
(1) Aerodynamic particle size distribution testing of inhalation aerosols and powders.
(2) Fine particle fraction evaluation for inhalation formulations.
(3) Delivered dose uniformity testing of inhalers.
(4) Research and development of inhalation drug delivery systems.
(5) Quality control testing of metered-dose inhalers (MDI), dry powder inhalers (DPI), and nasal sprays.
