Determination of Mineral Contents in Non-Alcoholic Beverages

This technical report outlines a method for analyzing mineral content in non-alcoholic beverages, specifically focusing on elements such as calcium, magnesium, sodium, potassium, and iron. The analysis employs flame atomic absorption spectroscopy (AAS) using instruments like the novAA 800, ZEEnit 700P, and contrAA 800. The report describes the preparation of beverage samples, which involves dilution with hydrochloric acid and a buffer solution. Calibration standards are prepared automatically by an autosampler, ensuring accurate measurement across varying concentrations. The report details the instrumentation parameters and method settings necessary for effective analysis. It also discusses the advantages of using the High Resolution Continuum Source AAS for simultaneous measurement of multiple analytes. The findings include measurement results and confidence ranges for various beverage samples, demonstrating the effectiveness of the described method in quality control laboratories. The report concludes with a discussion on the adaptability of the method for further applications, including the analysis of toxic elements.
