APSD of Dry Powder Inhalers (DPIs)

NGI Preseparator

For the collection of large mass, non-inhalable powder blouses typically emitted from a DPI prior to entry into the impactor, to prevent impactor over-loading.

• High capacity
• High efficiency
• Two-stage separation
• Sharp and reproducible cut-point between 10-15 microns (depending on flow rate)

Induction Port P1 Measurement Adapter

Used together with the Critical Flow Controller, the Induction Port P1 Measurement Adapter can be placed between the inhaler and the induction port to measure the pressure drop (P1) over the inhaler under test in the absence of a DUSA for DPIs.
