PURPOSE:To control the temp. of a test liquid to a constant temp. with high accuracy and to improve the accuracy of an analysis by providing a thermostatic chamber for a piping just before supply of the test liquid to a detection part in a thermostatic chamber as well. CONSTITUTION:Water 11, standard phosphoric acid soln. 12, electrolyte 13, etc., of a measurement part 25 are supplied through a mixing pipe by metering pumps 17, 18 to the detection part 21 in the thermostatic chamber 22 for the detection part, by which a flow analysis is executed. The thermostatic chamber for the piping including the pipe 19 just before said chamber 22 is also provided. The temp. of the test liquid is controlled to the constant temp. with the higher accuracy than in the case in which said chamber is not provided. The accuracy of the analysis is thus improved.
