Abstract (en)

[origin: CA2460767A1] The invention relates to a device for determining physical and chemical parameters such as pH value, moisture content or electrical conductivity of aerosol formulations discharged from metered dosed inhalers. The device is essentially comprised of a housing with a measuring chamber, of a measuring electrode and of a device for fixing and opening an aerosol cartridge. In order to carry out a determination, the aerosol to be analyzed is directly transferred out of the cartridge, such as one used in aerosol inhalers, and into a measuring chamber inside of which the measuring electrode carries out the desired measurement.
