摘要： PROBLEM TO BE SOLVED: To provide a technology capable of separating ion to be detected in a gas phase of atmospheric pressure or near it with a simple configuration and introducing it efficiently into a mass spectrometer or ion detector on a post stage, for improved detection precision at an apparatus on post stage. SOLUTION: An hour glass type flow channel, whose cross sectional area gradually decreases and then gradually increases, is configured along the flow direction of the gas containing ion. A potential difference is provided between an electrode arranged at the upper part of the hour glass and the inner wall of the hour glass flow channel as well as between the inner wall of the hour glass flow channel and the electrode arranged at the lower part of the hour glass. Accordingly, the ion having the ion mobility of a predetermined range is converged into the central part of a flow channel for transmission, while the ion having the ion mobility beyond the predetermined range is caused to advance toward the flow channel inner wall for discharge to the outside of the system.

摘要： PROBLEM TO BE SOLVED: To provide a monitoring device having high selectivity, being a small-sized analyzer dispensing with a vacuum system. SOLUTION: Two kinds of atmospheric pressure ion sources, namely, an atmospheric pressure ion source (non-dissociative atmospheric pressure ion source) for generating mainly molecular weight-related ions and an atmospheric pressure ion source (dissociative atmospheric pressure ion source) for generating mainly dissociated ions, are provided on an ion mobility spectrometer, to thereby provide a switching mechanism between the non-dissociative ion source and the dissociative ion source. A database is provided, wherein characteristic values (an ion mobility or values related thereto) of the molecular weight-related ions generated from the non-dissociative ion source and the dissociated ions generated from the dissociative ion source are registered relative to each measuring object material. When ions agreeing with the database are detected respectively in both modes of the non-dissociative ion source and the dissociative ion source, it is determined that the measuring object material is detected. In this case, existence of the dissociated ions is checked during operation of the non-dissociative ion source, and existence of the molecular weight-related ions is checked reversely during operation of the dissociative ion source, and the result is allowed to contribute to determination, to thereby improve reliability.

摘要： PROBLEM TO BE SOLVED: To improve heating efficiency and make a device compact by temperature-adjusting a part of a passage, and moving the temperature-adjusted portion in conformity to the speed of a fluid. SOLUTION: A sample from a river, a pond, or the water service and a reagent from a reagent container 5 are fed to a sample passage 1 and a reagent passage 2 by pumps 4, 14 respectively, and they are merged at the confluence X and fed to a waste liquid container 13 through a reaction detection passage 3. When the pumps 4, 14 are operated at the constant flow, the mixed liquid flows at the constant speed, and a temperature adjuster 12 is moved at this speed. Reaction proceeds only at the portion of the temperature adjuster 12 and hardly proceeds at the other portion. An absorption photometer 7 shows a peak response, and the chemical oxygen required quantity can be determined from the height of this peak. The heating region is minimized by this method, heating efficiency is improved, and the device can be made compact.
