Research

Dr. Nelson's focus is in trace elemental analysis for the food and beverage industry. Projects include but are not limited to: determining geographic origins, studying toxic and life essential elements, and identifying elemental contamination from packaging and processing. To accomplish these challenging projects, state-of-the-art instrumentation from Agilent Technologies is used. Analytical techniques include MP-AES, ICP-OES, ICP-MS, and ICP-MS/MS for total elemental analysis GC-ICP-MS and HPLC-ICP-MS for elemental speciation analysis.
