Device for determining aerosol particle size distributions |
| abstract |
The measurement of the particle size distribution of an aerosol is of crucial importance in pharmaceutical development. A prerequisite for this is a valid method, e.g. the cascade impactor method described in the pharmacopoeias. It requires measurement of the active substance concentration in order to determine the particle size distribution. The invention provides a process which makes it possible to measure the size of aerosol droplets containing pharmaceutical substances which are unstable in the event of changes in the pH. |
