PURPOSE:To expedite the exchange of liquid and to improve response speed by providing a pumping mechanism which is operated so that the liquid feeding directions are sequentially and repeatedly switched in the forward direction and the reverse direction. CONSTITUTION:The liquid flowing type analyzing meter 1 is constituted by a standard liquid bottle 2, a pump 3, a sample feeding part 4, a detector 5, and a used liquid bottle 6 which are connected by a solution communicating pipe 7. When the sample and the standard liquid pass the detector 5 part, the pump 3 is operated so that the liquid feeding directions are repeatedly switched in the forward direction and reverse direction by the command from a pump control device 12. In the present invention, since the liquid feeding directions are repeatedly switched in the forward and reverse directions, the stirring effect of the solution at the detecting part of the detector is excellent, the exchange of the liquid at the detector part is quick, and the response speed as a whole becomes extremely fast. |
