USP Monographs (Generic Drug Development)

USP Monographs are most commonly used for product release testing, but may also be considered during product development. These product-specific monographs call for the use of test equipment not hitherto specified in the general USP/ Ph.Eur. chapters on OIPs and are based on equipment and methods used in the original development of these products.

The monograph specified measurement to be conducted using a standard Andersen Cascade Impactor (ACI) equipped with a specially modified induction port. An additional inlet sleeve is provided, effortlessly attachable to the induction port inlet, enabling seamless use with regular mouthpiece adapters found on USP/Next Generation Impactor (NGI) induction ports.

Contrary to the powder method specifying testing at 60 L/min, the monographs recommend using the 28.3L/min version of the ACI (Stages 0 – 7 plus filter stage) for measuring Aerosol Particle Size Distribution (ASPD) for both aerosols and powders.

Products featured here:

  • Anderson Cascade Impactor (ACI)
  • ACI Preseparator for FP/Salmeterol Powders,
  • ACI Inlet Cone for FP/Salmeterol Aerosols.
