经由毛细管的参考物质引入
摘要：
本发明公开了一种用于质谱仪的质量校准装置，它包括毛细管、在第一点处耦合到毛细管的被分析物离子源、在第一点下游的第二点耦合到毛细管的参考物质离子源、以及在第一点和第二点下游的第三点处耦合到毛细管的质量分析仪。参考物质离子源可以经由三通连接部耦合到毛细管。参考物质离子源包括室、位于室内部的离子化器件、以及一个或多个参考物质源，所述一个或多个参考物质源位于室内部或者位于室外部并耦合到室。
摘要（英）：

A mass calibration apparatus for a mass spectrometer includes a capillary, an analyte ion source coupled to the capillary at a first point, a reference mass ion source coupled to the capillary at a second point, downstream from the first point, and a mass analyzer coupled to the capillary at a third point downstream from the first and second points. The reference mass ion source may be coupled tothe capillary via a tee junction. The reference mass ion source includes a chamber, an ionization device situated within the chamber and one or more reference mass sources that are situated internally within the chamber or are situated external to and coupled to the chamber.
