Plume & Sound Analysis

ASTECH can supply full / semi automated workstations for carrying out the automatic analysis of pMDI inhaler plumes and sounds. These automated solutions utilize modular automation from our library of respiratory products such as the DHWF for device waste/dose firing and our custom storage facilities for holding up to 150 devices prior to processing.

Plume Analysis

A plethora of recorded data can be gathered very quickly using this type of technology. ASTECH provide a solution where the shake profile is fully configurable for various shake simulations including linear, arc inversion, rotational etc. When the pMDI is fired ASTECH use state of art image capturing technology to record the plume profile. Profiles are stored in a secure database environment for easy retrieval and analysis.

Generated data can be used for R&D of next generation devices prior to launch or for the further development of an existing device. The technology can also be used for batch release testing using a simple “Pass / Fail” of the plume against a previously stored “good plume”. This type of system is often employed near the production line to give immediate feedback for production batches.

Sound Analysis

ASTECH can also record the sound each pMDI makes as it is fired. A “bad fire” will give a different sound signature to “good fire”. This can be characterized using in-built analysis software. Again, this data can be securely stored, retrieved and analysed. Alternatively, it can be used to provide simple “Pass / Fail” decisions for Analysts testing production batches.
