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
