High-precision measurements are possible while eliminating the influence of magnesium!
After adding the reagents to prepare the sample under specified conditions, the injection of the titrant is performed. The minimum injection volume (0.015 ml) achieved by the module's syringe driver ensures very high precision, with a maximum difference of only three drops even in two consecutive measurements using the same standard sample. Additionally, improvements in the software have accelerated the injection of the titrant in the initial stages, while slowing down the injection rate as it approaches the endpoint, ensuring even higher accuracy. This method is a modification of the method developed by Reilly (published in Analytical Chemistry). By adjusting the pH of the solution, magnesium precipitates and is not included in the titration target. It is specialized for calcium even in the presence of large amounts of magnesium. The measurement wavelength is adjusted to the calcium–calcon (Ca–Calcon) complex, while the reference wavelength is set to the EDTA–calcon complex, allowing for accurate and reproducible detection of the endpoint.

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.
