Introduction
Ensuring food safety means closely monitoring both toxic contaminants and key nutritional elements. Under China’s GB 5009.268-2025 standard, labs must accurately measure 30 metals and metalloids using inductively coupled plasma mass spectrometry (ICP-MS). In comparison to other analytical techniques, ICP-MS has the advantages of multi-element detection capability, low detection limits, high speed of analysis, wide dynamic range, etc. However, results are affected by polyatomic interferences and doubly charged species, which need to be accounted for by applying mathematical corrections and/or using collision/reaction mechanisms. Major elements (such as Na, K, Ca and Mg) in food should be analyzed in the same analytical run as the trace elements.
This study demonstrates the ability of the NexION® 1100 ICP-MS to provide the precision and reliability needed to exceed China’s GB 5009.268-2025 standard.
