• A mass spectrometric system equipped with the multi-collectors and peak selectors is investigated. The principal features of this method are to make a rapid wide mass range scanning by the rapid voltage scanning of shorter range and to make a simultaneous recording of multi-components with fast response through the multi-channel peak selectors. The graphic representation of ion optics is presented for determining the design parameters. Practical applications are given on the respiratory gas analysis. Several technical key points such as determining the accurate collector position, the response of the system, and the characteristics of the gate circuit which is the central part of the peak selector, are discussed with the mind of applying this system to the respiratory gas analysis.
