Title:
APPARATUS AND METHOD FOR MEASURING TOTAL PHOSPHORUS AND TOTAL NITROGEN
Document Type and Number:
WIPO Patent Application WO/2019/189952
Kind Code:
A1
Abstract:
The present invention relates to an apparatus and a method for measuring total phosphorus and total nitrogen, wherein a consumable material of the apparatus for measuring total phosphorus and total nitrogen is reduced and reagent consumption and waste liquid generation are minimized through a multi-port valve, a metering pump, and a common channel located therebetween. In the apparatus and the method for measuring total phosphorus and total nitrogen according to the present invention, water, a sample, a regent, and the like are sequentially suctioned and filled in the common channel located between the multi-port valve and the metering pump and then sent to an oxidation reactor, or an oxidation reactant and a coloring material are suctioned and filled in the common channel and then sent to a detector, and thus a process can be simplified. In addition, the measurement apparatus of the present invention can remarkably reduce the number and the length of pumps and pipes (tubes) required for facility operation and thus is manufactured at a low cost and easily maintained and managed. Further, the present invention sequentially suctions and fills a sample and a regent in the common channel and increases preciseness by using a minimum amount of sample through a precise pump, while reducing the number and the length of pipes (tubes), and thus can reduce the amount of reagent consumed wastefully and accordingly reduce waste liquid generation.
