摘要
The present invention relates to a total phosphorus or total nitrogen measuring device and a total phosphorus or total nitrogen measuring method using the same. More particularly, the present invention relates to an apparatus for measuring total phosphorus or total nitrogen contained in a sample, The present invention relates to a total nitrogen or total nitrogen measuring device and a total nitrogen or total nitrogen measuring method using the same. To this end, the total phosphorus or total nitrogen measuring device includes a sample and reagent supply unit for supplying the sample and the reagent to be measured; A sample and reagent supply pump for transferring a sample and reagent supplied from the sample and reagent supply unit in a fixed amount; An oxidation reaction tank for preheating the transferred sample by pressurization heating; A mixing tank transfer pump for transferring the pretreated sample in the oxidation tank; A mixing tank for diluting and mixing the pretreated sample, the diluted water and the pretreated sample supplied with the reaction reagent; A detector transfer pump for transferring diluted and mixed samples to a detector in a mixing chamber; A detector for measuring the concentration of total phosphorus or total nitrogen contained in the sample; And a 3-way valve disposed downstream of the sample supply pump for supplying the sample to the oxidation reaction tank or the mixing tank.
