    摘要: A mass spectrometry system arrangement includes a curved ion guide, where the curve of the ion guide is positioned such that a portion of the ion optics are visible from at the ion guide entrance, e.g. line of sight or z-axis. There are four electrodes parallel with each other and the central curved axis. Each electrode is equally radially spaced from the curved central axis. For each cross section of the ion guide, the central curved axis being positioned at the origin, the curved electrodes being radially positioned at 45°, 135°, 225°, and 315°. Depending upon the system, a blocking device is positioned external to the ion guide but within the “line of sight” or positioned tangential to the rising section of the bent ion guide.

    摘要: A system for preventing backflow as part of an ion source arrangement is introduced. Such a system incorporates a novel continuous flow guide within a source, such as an API ion source. In the spray direction, the cross-sectional area that defines the first portion of the internal volume initially decreases in a convergent-like manner and thereafter increases in a divergent-like manner towards the exit opening of the source housing. Such a flow guide has been designed as an integral part of an ion source housing to provide for an optimal unidirectional flow past a sampling orifice of a mass spectrometer inlet. Accordingly, the novel design of the present invention prevents recirculation and thus minimizes carryover, chemical noise, and source turbulence and as an added benefit, enables a user to easily clean such a system during maintenance.
