Abstract

PURPOSE: To continuously prepare standard solution by injecting high-concentration standard solution at a fixed flow into a fixed flow of sample water.
CONSTITUTION: The detector A of a measuring device, such as ion densitometer, the results of measurement are indicated in a logarithmic scale, and an overflow tank 1a are connected by means of a sample water feed pipe 1 with a throttle valve 1b. The standard solution preparing piping system 2 having a high-concentration standard solution storage tank 2a, metering pump 2b and on-off valve 2c is connected to the sample water feed pipe 1. As a result of this, at the time of measuring the sample water, the sample water is regulated to a constant head by the overflow tank 1a and is led into the detector A. On the other hand, at the time of calibration, the on-off valve 2c opens in the state that the flow of the sample water is made contant. This causes the metering pump 2b to operate to inject every fixed amount of the high-concentration standard solution into the sample water. These are then mixed in the feed pipe 1 and the mixed solution is supplied continuously as the standard solution of the specified concentration to the detector A.
