Specifications

Certifications/ComplianceThe Andersen 20-800 series design is specifically cited within various world pharmacopeia (e.g., United States Pharmacopeia Chapter 601) to characterize metered-dose (MDI) and dry powder-dose inhalers (DPI), nebulizers, nasal sprays, and other pulmonary drugs. Non-Viable Cascade Impactors are especially relevant during research, quality assurance and equivalency testing. Various introduction kits are available for these specialized applications (see USP Accessory Parts). The testing of inhalation drugs relates well to the cascade impactor. The size ranges collected are considered inhalable (generally <10um). Just as the inhalation drugs should consistently arrive within the respiratory system into their target regions, the various stages represent the cut-off sizes where deposition occurs within the lungs. All new impactor systems undergo an ACIVIS inspection before shipping and are flow calibrated with a factory supplied vacuum pump where applicable. A unique serial number is given to multistage system to further track system history and allow data retrieval. The serial number is imprinted on each stage adjacent to the stage number.
