具有单个或多个细长孔径和质谱仪系统的离子转移管

Ion Transfer Tube Having Single or Multiple Elongate Bore Segments and Mass Spectrometer System
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（中）：

用于质谱仪的离子转移管包括具有入口端和出口端的管构件; 以及至少一个孔，其从所述入口端延伸到所述管构件到所述出口端，所述至少一个孔具有非圆形横截面。 形成离子转移管的方法包括以下步骤：提供具有长度和内孔的管构件，所述内孔具有圆形横截面的壁; 并且蚀刻或侵蚀与壁相邻的管构件的部分，以便形成具有非圆形横截面的扩大孔。
