New flow controller firmware from Copley Scientific streamlines DPI testing

10 March 2015; Nottingham, UK: Copley Scientific has released new firmware for its Critical Flow Controller Model TPK 2000 that streamlines dry powder inhaler (DPI) testing, delivering time and cost savings while safeguarding data quality. The new firmware allows the TPK 2000, a standard accessory for DPI testing, to be configured to leak test a cascade impactor, without the need for any additional equipment. By eliminating the need for repeated connection/disconnection to/from leak testing equipment the TPK 2000 firmware speeds up testing while at the same time encouraging good operating practice that ensures data integrity.

Cascade impactors are used to measure aerodynamic particle size distribution (APSD), a critical quality attribute for all DPIs. To achieve calibrated performance, the airflow rate through an impactor must be tightly controlled. Leak testing provides an essential check of system suitability, ensuring there are no leaks of air into the impactor that could compromise aerodynamic performance of stages downstream of the leak itself.

The new TPK 2000 firmware delivers cost savings by eliminating the need for any additional leak testing equipment. It also saves time during cascade impactor testing, since the TPK 2000 and cascade impactor can remain in-situ (as during routine testing) without disconnection for the purposes of introducing a separate leak tester in between. By enabling seamless leak testing within the cascade impaction testing workflow the new TPK 2000 firmware encourages leak testing ahead of every analysis, as recommended by the manufacturer, thereby safeguarding data quality.
