Abstract

PURPOSE: To more speedily and exactly measure object liquid with small filtering quantity as much as possible by collecting a component to be measured, which is filtered and sucked by temporally stopping a flow route, opening a valve again when the measurement of a sensor is started and carrying the component to be measured to a measuring part so as to be pushed-out with carrier liquid.
CONSTITUTION: When the operation to suck the component of a measuring object is executed through a filter 3, a flow route 4 is temporally opened in the downstream side of a filter part by an opening/closing valve 6 and the flow of the carrier liquid is stopped. Then, only filtering operation is executed by the sucking operation of a pump 9 and the component of the measuring object is collected in the measuring part side of a sensor 8 in the downstream side of the filter part in the flow roue. In a state that the fixed quantity of the component is integrated, the opening/closing valve is opened and the collected component of the measuring object is carried to the measuring part of the sensor in a concentrated state so as to be pushed-out by the carrier liquid. Then, the measuring part is measured. Accordingly, the time delay of the measurement by the sensor is practically canceled and the concentration of the measuring object component brought into contact with the sensor can be enough secured. Then, speedy and exact measurement can be executed. Further, the loss of the filtering quantity is small and the efficient measurement can be executed by sampling the small quantity of the object liquid.
