Abstract
PURPOSE:To largely decrease the substituting time required for returning the effluent after the completion of analysis of the effluent at the time of starting in a piping system, by providing an effluent draining path between a mixed and separating columns, substituting the concentration of the effluent quickly, and equalizing the columns. CONSTITUTION:The gas from a pressurized gas source 20 is sent to a hermetically sealed container provided with a plurality of effluent tanks through a reducing valve 7, a pressure gage 6, and a gas piping system 8. The pressurized effluents 9, 10, and 11 are stored in the hermetically sealed container 12. The container is connected to a valve 4 through a multiple directional valve 1, a mixer 2, and a three way joint 3 in one way and to a pump 5 on the other way. When the analysis is started, the column 22 is equalized by the effluent 9. After a sampple has been introduced, the multiple directional valve 1 is sequentially changed to the effluents 10 and 11 in accordance with the an analyzing time, and the sample component is eluted and analyzed. In this constitution, the substituting time for returning the effluent after the completion of analysis of the effluentat the time of starting in the piping system is reduced to a large extent.
