Multi-stage Cascade Impactor (NGI)

Specially designed for aerodynamic characteristics determination of inhaled fine particles, model HRH-ZJQ160 multi-stage cascade impactor consists of a smart pump, a pressure detector, cascade impactors, pre-separator (DPIs), an induction port and accessories. It complies with instrument qualifications of aerodynamic characteristics determination of inhaled fine particles in USP, Ph. Eur. and ChP 2020.

Features: 

• Contain 7-stage impactors and micro-orifice collector (MOC), easy to open, collect samples from collection cups and prepare for analysis.
• With 8 removable collection cups, for easy cleaning and replacement.
• Used for APSD tests for MDIs/DPIs/Nebulizers/Nasal Sprays. DPIs can be tested with a pre-separator, effectively removing coarse particles of 10-15 microns.
• The collection cups have the impact surface placed on a tray which could facilitate sampling and directly under nozzles. The tray facilitates efficient sample collection.
