  • Method for checking the permeability rate of a closed container
    Patent number: 8087286
    Abstract: In a method for checking the permeability rate of a closed container (3) with respect to a medium, in particular for checking the permeability rate of a film-type container for accommodating a film container for accommodating a pharmaceutical active constituent formulation, the container (3) is filled with a medium, charged with a gas, and the increase in the amount of medium in the gas is then analysed.

  • Process for determining the particle size distribution of an aerosol and apparatus for carrying out such a process
    Patent number: 7453556
    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.
