摘要： Disclosed is an improved 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.

摘要： A system and method are provided for minimizing the effects of background signals in masking signals indicating the presence of substances to be detected such as contaminants in materials moving rapidly along a conveyor. The contaminants detected may include nitrogen containing compounds and hydrocarbons. The system and method of the present invention minimize during detection of the presence or absence of such substances, the number of falsely positive indications of the presence of such substances due to background signals and changes in background signals. The substances detected are divided into first and second sample portions and the respective portions are heated. The first heated portion is mixed with ozone to cause a chemical reaction therewith in order to generate radiation by chemiluminescence having characteristic wavelengths related to substances in the first portion. The second portion heated is also mixed with ozone to cause a chemical reaction therewith in order to generate radiation by chemiluminescence having characteristic wavelengths related to substances in the second portion. The radiation of the respective first and second portions is selectively detected. The heating and detecting steps are performed in a manner so as to yield a higher level of detected radiation from one of the portions of the sample then the other for at least some of the selected compounds being detected. Electrical signals from the respective first and second portions are generated and compared in order to determine the presence or absence of selected compounds in the sample. Appropriate reject signals for a bottle sorting system are generated accordingly.

摘要： A system for injecting liquid into containers moving through an inspection station at variable speeds without spilling liquid over the outside of, or between, the containers for inspecting the containers for the presence of certain substances such as potential contaminants, such as ammonium salts or amine salts in glass or plastic bottles. The movements of each container is tracked with sensors upstream of a high speed injector, and one or more nozzles is timed to inject liquid in a narrow, high velocity stream only while the top opening of a container is under the nozzle(s). The liquid is employed to enhance liberation of vapors from within the containers for detection of the contaminants in the containers.

摘要： A highly selective, sensitive, fast detection system and method are disclosed for detecting vapors of specific compounds in air. Vapors emanating from compounds such as explosives, or stripped from surfaces using heat and suction from a hand-held sample gun, are collected on surfaces coated with gas chromatograph (GC) material which trap explosives vapors but repel nitric oxide, then are desorbed and concentrated in one or more cold spot concentrators, A high speed gas chromatograph (GC) separates the vapors, after which specific vapors are decomposed in two pyrolyzers arranged in parallel and the resulting nitric oxide is detected, A low temperature pyrolyzer with silver produces NO from nitramines or nitrite esters; a high temperature pyrolyzer decomposes all explosives vapors to permit detection of the remaining explosives, Also disclosed is a series arrangement of pyrolyzers and gas chromatographs and an NO detector to time-shift detection of certain vapors and facilitate very fast GC analyses, The use of hydrogen as a carrier gas, plus unique collectors and concentrators, high speed heaters, NO detectors, and very fast, temperature-programmable GC's enhance selectivity, sensitivity and speed of detection,
