Trace elemental screening and speciation analysis of food is receiving global attention. Some elements are an essential part of a healthy diet, but others, such as lead, mercury, arsenic and cadmium, offer no nutritional benefits to humans and are actually toxic.
Because food is the primary conduit for elements to enter humans, regulators are becoming stricter and requiring manufacturers to monitor levels of hazardous elements in foodstuffs. In addition, food manufacturers and suppliers are now legally required to label food with ingredients and nutritional information. All of this is driving industry-wide demand for fast, sensitive, reliable and cost-effective testing methods for high-throughput trace elemental analysis of food.
