PURPOSE:To analyze both anion and cation species simply injecting a solution to be measured once, by a method wherein a solution to be measured in introduced into a cation measuring system to analyze the caion and then, a specified portion of the fluid introduced into an anion measuring system to analyze the anion species. CONSTITUTION:An elution liquid in a tank 1a is fed to a waste liquor tank 1d with a feed pump 2a via a passage of an injector 5, a column 7a and an injector 5'. An elution liquid in a tank 1b is fed to a waste liquor tank 1f with a pump 2b via a path of the injector 5' and an internal chamber 92 of a suppressor 9. A removing liquid in a tank 1c is fed to a waste liquor tank 1e with a pump 2c via an external chamber 93 of the suppressor 9. A liquid to be inspected is injected into a connection port 54 and the injector 5 is turned ON to change the passage to the broken line from the solid line. The liquid being inspected reaches column 7a to separate the cation and the conductivity is detected with a detector 8a. The anion is separated with a column 7b via the injector 5' turned ON and the conductivity is detected with a detector 8b. |
