High-Temperature Digestion of Baby Food and Infant Formula for Accurate Analysis of Arsenic

Baby and infant foods are subject to close scrutiny for trace metal contamination from cultivation or processing. Low parts per billion (ppb) levels of inorganic contaminants such as arsenic, cadmium, lead, mercury, and others must be accurately analyzed by inductively coupled plasma-mass spectrometry (ICP-MS). This webinar will discuss the challenges of preparing these samples for ICP-MS analysis as well as how to choose the right microwave digestion system for this application.

Event Overview:

Perhaps more than any other foods, baby and infant foods are subject to close scrutiny for trace metal contamination from cultivation or processing. Low ppb levels of inorganic contaminants such as arsenic, cadmium, lead, mercury, and others must be accurately analyzed by ICP-MS.

The US Food and Drug Administration (FDA) EAM 4.7 method has defined 2 procedures for sample digestion followed by inductively coupled plasma-mass spectrometry (ICP-MS) determination. Criteria for the choice of technology (oven vs autoclave digestion) will be presented in this webinar, followed by application examples of spiked baby food matrices. Special attention will be given to the accurate determination of arsenic, which can be impeded by residual carbon in ICP-MS analysis. Finally, other useful resources for trace metal analysis will be discussed.

Key Learning Objectives:

• Learn about challenges and solutions in acid digestion of food samples for ICP-MS analysis
• Understand FDA EAM method 4.7: The 2 procedures for microwave digestion
• Learn about the arsenic enhancement effect in ICP-MS analysis and how to overcome it

Who Should Attend:

• Lab chemists doing trace metal analysis of food samples in R&D, QC, or analytical service labs
• Food chemists in state or municipal laboratories
• Laboratory managers of ICP and trace metal labs
• Academic food chemists
