Abstract
An analysis device having a liquid chromatograph prevents a plurality of streams from being unusable at the same time Whether a usable stream is 0 or not among streams 1, 2, and 3 is determined. In a case where none of the streams is usable, the control unit skips a sample introduction in the cycle; and where there is one usable stream in the cycle, the stream is used. In a case where there are multiple streams that are usable in the cycle, and there are multiple streams of which the remaining number of uses of a separation column is the minimum, the stream having the smallest stream number is used; and where there is one stream of which the remaining number of uses of a separation column is the minimum, the stream to which the separation column having the minimum remaining number of uses is connected and used.
