自動試料注入装置。 A six-way valve equipped with a sample loop is connected between a sample supply pipe equipped with a sample liquid feeding means and a sample discharge pipe, and between a mobile phase supply pipe and a column flow path. Therefore, in an automatic sample injection device configured to pump a sample in a sample loop to a column, air bubbles flowing through the sample supply pipe can be detected when the sample is flowed into the sample supply pipe before switching the flow path of the six-way valve. a first air bubble detector installed near the six-way valve of the sample supply pipe to detect air bubbles flowing through the sample discharge pipe, and a second air bubble detector installed near the six-way valve of the sample discharge pipe to detect air bubbles flowing through the sample discharge pipe; a counting means for adding the number of bubbles detected by the first bubble detector and subtracting the number of bubbles detected by the second bubble detector; and a counting means for adding the number of bubbles detected by the first bubble detector and subtracting the number of bubbles detected by the second bubble detector; An automatic sample injection device comprising output means for sending a signal to stop the means and then outputting a flow path switching signal to the six-way valve.
