摘要：
One aspect of the invention features a method of analyzing dose metered devices by: spraying an aerosol from a metered dose device directly into a spray chamber of a mass spectrometer detector by firing a dose from a metered dose device, for example a pMDI, by depressing the pMDI in its actuator, which spraying step is optionally preceded by a step of priming the drug container of the metered dose device; ionizing the aerosol; and identifying and quantifying the content of the dose using the detector.
