Abstract
A sample solution contained in a sample vessel is analyzed using a positive ion detector and a negative ion detector. The positive ion detector and the negative ion detector are supplied with the sample solution from the sample vessel, while isolating the positive ion detector and the negative ion detector from one another. Accordingly, the sample solution is not supplied from the positive ion detector to the negative ion detector, and the sample solution is not supplied from the negative ion detector to the positive ion detector. The positive ion detector and negative ion detector are preferably supplied with sample solution from the sample vessel using a bidirectional valve having an input port and first and second output ports. The input port is connected to the sample vessel, the first output port is connected to the first detector, and the second output port is connected to the second detector.
