徴とする液体クロマトグラフ検出器用コック。The first flow path has a sample side flow path and a control side flow path in the same detector, and the first flow path directly disposes the solution exiting the sample side flow path as waste liquid, and the first flow path disposes the solution exiting the sample side flow path as a direct waste liquid. In the cock that switches between the flow path and the second flow path for discharging liquid, the cock connects the sample side flow path to four ports that are respectively connected to the sample side flow path, both ends of the control side flow path, and the waste liquid side flow path. a stator having a passage groove that communicates a port connected to one end of the opposite side passage with a port connected to one end of the opposite side passage, and a rotor having a passage groove that is longer than between adjacent ports provided in the stator, When switching from the first flow path to the second flow path by rotating the flow path, at least one of the two ports connected to the opposite flow path is connected to the waste liquid side flow path via the flow path groove. A cock for a liquid chromatograph detector, characterized by communicating with a port.
