ABSTRACT:
An analytical system for a trace element, which includes a pressure pump for continuously feeding a carrier solution, a first sample introduction unit for introducing a sample and a reagent using sample loops and switching valves, a first flow passage including a pre-treatment unit for pre-treating the sample by heating, and a second flow passage separated from in pressure from the first flow passage, wherein the sample pre-treated in the first flow passage is sampled into the second flow passage through a second sample introduction unit, and the sample thus sampled in the second flow passage is allowed to coloredly react with a coloring agent and measured in absorbance.
