Reduced Plasma Flow Method for the Analysis of Fruit Juices using the Agilent 5110 ICP-OES

Analytical testing of food and beverage products is fundamental to product-safety, regulatory compliance, and product labeling. To meet strict quality control (QC) measures for inorganic components, regular testing is performed to identify and quantify nutrients, micronutrients, and heavy metals.

To ensure that food testing laboratories follow the correct measurement requirements, they are closely examined by regulatory bodies. As a result, regulated methods have guided the procedures and instrumentation adopted by laboratories in the food industry. Traditionally, many food-related regulated methods specified atomic absorption spectrometry (AAS). However, more recent publications of regulated methods, including ILNAS-EN 16943:2017 and AOAC Official Method 2011.14, have described the analysis of food and beverages by Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES). The benefits of ICP-OES compared to AAS range from enhanced analytical speed to greater performance capabilities enabling multi-element, high throughput, unattended analysis of many sample-types. With its extensive range of software and hardware features that facilitate a fast, stable, and efficient analysis, the Agilent 5110 ICP-OES is ideally suited to meet the evolving needs of the food industry.

In this study, the Agilent 5110 Vertical Dual View (VDV) ICP-OES was operated with an argon plasma flow rate under 10 L/min to measure Al, As, Ca, Cd, Cu, Fe, K, Mg, Mn, Na, Ni, P, Pb, S, Sn, Zn in a range of fruit juices.
