Abstract
A leak rate testing system for pressured containers such as inhalers includes a test chamber holding the pressurized containers and accumulating compounds leaking from the containers. A sample cell receives the compounds from the chamber and a spectroscopy system obtains spectral responses of compounds in the sample cell so that a controller can determine leak rates over time.
