    摘要: An apparatus for directly connecting an analytical column and a mass spectrometer comprising a fixed member having at least four holes which respectively introduce washing solution, eluate containing a component eluted from the analytical column, desalting solution and eluent for eluting the component, and a movable member rotated with respect to an axis having at least four tubes around the axis and mounting the four trapping columns, whereby the trapping columns are respectively washed, trapped, desalted and eluted in parallel. Furthermore, a common trapping column may be used instead of the four trapping columns by controlling the apparatus with four analytical modes.
