NEXT GENERATION IMPACTOR (NGI ) 

The Next Generation Impactor (NGI), was launched in 2000 and was subsequently accepted into the European Pharmacopoeia as Apparatus E and into the United States Pharmacopeia
as Apparatus 5 and 6 in 2005.

Drawing on their extensive experience, the consortium developed a list of “musts” and “wants” for the new impactor. The result was an impactor having the following features:

• Designed by the pharmaceutical industry for inhaler testing

• Meets and exceeds all Ph.Eur. and USP specifications

• Particle size range: 0.24 – 11.7 microns (dependent on flow rate)

• Seven stages; five with cut-offs between 0.54 and 6.12 microns at flow rates from 30 to 100 L/min

• Excellent stage efficiency, accuracy and reproducibility

• Archivally calibrated flow rate range: 30 – 100 L/min

• Additional calibration at 15 L/min for nebuliser applications

• Supplied with full stage mensuration report (system suitability)

• Low inter-stage wall losses ensure good drug recovery (mass balance)

• User friendly design for maximum throughput and easy automation

• Electrically conductive; unaffected by static

• Design and archival calibration formally documented and published
