Calcium is one of the indispensable nutrients for the human body and plays an important role in the growth and development of the human body. Calcium is the most abundant mineral in the human body and participates in the entire life process. The amount of calcium is sufficient to maintain normal metabolism and enhance the body's adaptability to the living environment. Beverage is mainly added with calcium propionate, which has the functions of preserving and providing calcium source. At present, there are many methods for determining calcium in food. Atomic absorption spectroscopy is the first choice, but the sample needs to be digested before it can be determined, and the detection process is easily contaminated. Although the titration method is classic and mature and does not require advanced equipment, the operation process is cumbersome and time-consuming. Because the ion chromatograph of the Indigo dialysis ultrafiltration system has an automatic purification treatment function for dirty samples, an ion chromatography method was established for the determination of calcium in beverages. The sample was directly sampled after dilution and the measurement results were satisfactory.
