Safe, low cost MP-AES analysis of total metal content of a plant-based reference material following microwave digestion is presented. Elements that are difficult to analyze by FAAS such as B and P were included, with all data acquired in a single run. Accurate determinations over a wide concentration range and with better detection limits and sample throughput compared to FAAS were obtained.
