摘要： An ion transfer tube for a mass spectrometer comprises a tube member having an inlet end and an outlet end; and at least one bore extending through the tube member from the inlet end to the outlet end, the at least one bore having a non-circular cross section. A method of forming an ion transfer tube comprises the steps of providing a tube member having a length and an internal bore, the internal bore having a wall of circular cross section; and etching or eroding portions of the tube member adjacent to the wall so as to form an enlarged bore having a non-circular cross section.

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.
摘要翻译：引入了用于防止作为离子源装置的一部分的回流的系统。这样的系统在源内包含新颖的连续流动引导件，例如API离子源。在喷射方向上，限定内部容积的第一部分的横截面面积首先以收敛方式减小，然后以发散方式朝向源壳体的出口开口增加。这种流动引导件已被设计为离子源壳体的组成部分，以提供通过质谱仪入口的采样孔的最佳单向流动。因此，本发明的新颖设计防止再循环，从而使携带，化学噪声和源湍流最小化，并且作为附加的益处，使得用户能够在维护期间容易地清洁这样的系统。
