Continuous measurement of nitrate concentration in water is possible!
Method - Ion Selective Electrode Reagent 1 is added before analysis to activate the electrode. After that, the first measurement is taken. Next, a small amount of a high-concentration nitrate solution is added, and a second mV measurement is performed to calculate the results. If an extraction solution is used, cleaning with an ammonia-based cleaning solution is necessary after analysis to prevent cross-contamination. Many probes are affected by interference from nitrite and chloride, but in this method, using the extraction solution at the beginning of the analysis completely removes the influence of these two ions. Therefore, the only ion affecting the measurement is the nitrate ion (NO₃⁻).

Company information
Sunny Trading has consistently specialized in the import and sales of automatic control and labor-saving equipment since its establishment in 1961, actively introducing the latest high-performance machinery and equipment from Europe and the United States to the domestic market. The components for production machinery that we handle are widely adopted in industries such as machinery, electrical, and chemical, and we take pride in our extensive delivery track record to national government agencies, universities, research institutions, and the aerospace industry. The delivered parts are incorporated into machines to complete large production facilities, but confirming the compatibility of the products is essential for this process. We always strive to provide appropriate products by investing technical know-how and time for specification confirmation between overseas manufacturers and our customers. Additionally, we take responsibility for follow-up services, including on-site inspections of delivered products and maintenance. Unlike general trading companies that simply import and sell goods, we pride ourselves on being a trading company with engineering capabilities. Products are commercialized as machines by manufacturers, and they are actively utilized in core industries such as semiconductors, steel, shipbuilding, aerospace, packaging, logistics, and chemicals.
