摘要 |
An ultrapure water trap (22) is provided for retaining condensed water of water vapor which is formed in a TC oxidative reaction part (2), and a passage is so connected that an automatic sample injector (15) can collect ultrapure water from the ultrapure water trap (22) for injecting the same into the TC oxidative reaction part (2). The automatic sample injector (15) dilutes ordinary pure water which is outside this apparatus with the ultrapure water which is retained in the ultrapure water trap (22), thereby preparing a test solution having ultralow carbon concentration of not more than 50 ppbC in the interior of a TOC meter. |
