Abstract

To eliminate the time and effort for measuring and managing the volume of a solution to be analyzed to be introduced to an analyzer in performing quantitative analysis of a component with an unknown concentration in a sample by using a calibration curve, thereby performing accurate analysis.SOLUTION: In performing quantitative analysis of an unknown component included in a sample by using a calibration curve, a preparation device performs, by using the same absorption tube, introducing an absorbent absorbing gas into the absorption tube and causing the absorbent to absorb sample gas generated by decomposing the sample including the unknown component by heat to prepare a solution to be analyzed for the sample, and preparing a calibration curve solution, injects a diluted solution to the solution to be analyzed in the absorption tube and the calibration curve solution in the absorption tube to obtain constant-volume solutions, and introduces the solutions to an analyzer to perform analysis.SELECTED DRAWING: Figure 1
