Heavy Metals in Food: Digestion Strategies and Complete Sample Prep Workflow

Food & Feed Sample Preparation Webinar Series

Ensuring food and feed quality requires reliable determination of both contaminants and nutrients, yet sample preparation remains one of the most challenging and time-consuming steps in the analytical workflow. This webinar series introduces modern approaches to digestion and extraction that improve data quality, reduce reprocessing, and increase laboratory productivity. Through four dedicated events, covering heavy metals, organic contaminants, macro/trace minerals, and nutritional parameters such as fats, FAMEs, and amino acids, participants will discover optimized, practical workflows tailored to real-world food and feed testing.

Session: Heavy Metals in Food: Digestion Strategies and Complete Sample Prep Workflow

Heavy metals such as Pb, Cd, As, and Hg are strictly regulated in food and feed, requiring robust digestion and a well-controlled sample preparation workflow. This webinar covers best practices for microwave digestion of diverse food matrices using systems such as ETHOS and ultraWAVE 2 eco. A case study on baby food will illustrate common challenges such as matrix complexity, contamination control, and blank management. Participants will learn how to build a reliable sample-to-analysis workflow that ensures accuracy, reduces re-runs, and supports regulatory compliance.
