Abstract

PURPOSE:To contrive toward higher sensitivity of analysis by removing a high density of hydroxide or carbon ion as water or carbon dioxide respectively before the introduction of a sample solution into a separation column. CONSTITUTION:A regenerative liquid flows to a pretreatment column 11 from a regenerative liquid tank 1 to regenerate the column and then, pure water flows to said column from a pure water tank 2 to clean up the column 11. Thereafter, a sample solution flows to said column 11 from a sample solution tank 3 to exchange cation for hydrogen ion in the sample solution. Hydroxide ion reacting with the hydrogen ion formed changes to water and carbonate ion to carbon dioxide to turn the sample solution to a diluted solution. The sample solution flows into a concentration column 12 to trap analysis components. Then, an eluate flows to the concentration column 12 and the resulting effluent is passed through a precolumn 13 and a separation column 14 to separate the analysis components. After passed through a removing column 15, the effluent from the separation column 14 flows through a conductivity detector 51 to measure conductivity.

器５１により測定を行っている。In the figure, 4 is an eluent tank, and when performing concentration analysis, a sample solution is put into the sample solution tank 3. If the concentration of the analytical component is relatively high, it is injected into the sample loop 71 from the sample injection port 61, the sample solution in the sample loop 71 is introduced into the pre-column 13, and the component is transferred to the pre-column 13 and a separation column provided downstream thereof. 14 and conductivity measurement is performed using a conductivity detector 51. If the concentration of the analytical component is low, the sample solution is injected into the concentration column 12, the analytical components in the sample solution are concentrated in the concentration column 12, and then the components are separated using the pre-column 13 and the separation column 14 connected afterwards. , a conductivity detector 51 performs the measurement.

れる。On the other hand, alkaline solutions such as alkali carbonate or caustic alkaline solutions are generally used as absorbents for acidic gases such as hydrogen chloride, nitrogen oxides, and sulfur oxides. The method is to absorb the liquid and then analyze the target component in the absorbed liquid.

に短くなり、分離が不完全になることがあった。[Problems to be Solved by the Invention] However, when analyzing a highly concentrated alkaline solution such as the absorption liquid as a sample, the analyte components may be lost due to the elution effect of a large amount of hydroxide ions or carbonate ions in the sample solution. The retention time was extremely short compared to when a dilute solution was used as a sample, and separation was sometimes incomplete.

的な分析を行うことができなかった。In addition, when analyzing very small amounts of impurities, the method is to concentrate them in a concentration column and then separate them in a separation column. However, if a large amount of a highly concentrated alkaline solution is used as a sample and concentrated in the concentration column, the analytical components will elute from the concentration column. There is also the problem that recovery is incomplete, and conventional analysis systems cannot perform quantitative analysis.
