Abstract

PURPOSE: To ensure a quick and high-accuracy analysis with the simplified method, principle and structure of the device by supplying a small amount of the eluate to the column in a fixed current amount to elute the sulfied ion and then giving the continuous measurement to the ultraviolet absorption near the prescribed value of the solution.
CONSTITUTION: The analysis material is heated and dissolved via the reducing solution to generate the hydrogen sulfide, and hydrogen sulfide generation/absorption part W is provided to absorb the generated hydrogen sulfide. In addition, the following parts are provided: sulfied ion concentration/ultraviolet absorption measurement part X where the absorption concentration is carried out for the sulfide ion in the absorption liquid via the ion exchange resin along with the measurement for the ultraviolet absorption of the eluate; inorganic gas aspiration/sample residual liquid exhaustion part Y where the inorganic gas is blown in at the time of the hydrogen sulfide generation and the sample residual liquid is exhausted when the analysis is over; and automatic control part Z where each operation receives an automatic control based on the prescribed program. Then a small amount of the eluate is supplied to the column in a fixed current amount to elute the sulfide ion, and the continuous measurement is given to the ultraviolet absorption near 232nm of the eluate. In such way, a quick and high-accuracy analysis is ensured with the simplified method, principle and structure of the device each.
