Continuous measurement of copper ion concentration in water is possible!
Method - Colorimetric Analysis After adding the sample to the measurement cell, several reagents are added to adjust the conditions of the solution (such as pH and oxidation state). Subsequently, a blank measurement is performed to correct for the effects of temperature and turbidity. Then, the final reagent is added, which reacts with the solution to produce a color that is measured at the appropriate wavelength. The photometer used allows for highly accurate measurement results. This method is based on the reduction of copper(II) to copper(I) in acidic solutions. The neocuproine reagent specifically reacts with cuprous ions (Cu⁺). If present, iron can also be reduced to iron(II) (Fe²⁺) and may react with neocuproine. This method is specific to copper, and the cuprous-neocuproine complex has a clear and relatively strong absorbance, allowing for the measurement of low concentrations of copper at the ppb level. The influence of iron can be removed with additional reagents.

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.
