Abstract
A method and system for injecting liquid into containers and for inspecting containers for the presence of certain substances such as potential contaminants such as ammonium salts or amine salts in glass or plastic bottles. A high speed system and method are provided for detecting these contaminants in these bottles. Ammonia and amines can be detected by chemiluminescence of samples of volatiles emitted from the bottles during the high speed inspection process. A solution of Na.sub.2 CO.sub.3 is injected into the bottles in order to enhance the conversion of ammonium or amine salts to free ammonia or amines which are then released as vapors. This enhances the likelihood that a gas-phase detection system such as one using chemiluminescence detection techniques will detect the presence of contaminants containing ammonium salts or amine salts.
