Safe food is of primary concern to everyone. The recent prevalence of contaminants and adulterated, counterfeit or fraudulent food has led to an increase in public awareness and government regulations. Although newsworthy cases highlight contaminants at high levels, even low concentration levels can be dangerous such as arsenic (As) in baby food or selenium (Se) in solid and liquid supplements.
No food manufacturer wants heavy metals or other dangerous elements to end up in their products. However, they can enter production through intentional or incidental adulterants, such as lead (Pb) and chromium (Cr) in colorants or arsenic (As) and bromine (Br) from pesticides. It’s important to ensure these contaminants are not present at any stage of food production.
XRF provides fast, nondestructive elemental analysis of food, from starting materials to end products, as liquids, powders, solids and tissues. Our XRF analyzer portfolio includes high-throughput lab-based ED-XRF and WD-XRF, point-and-shoot handheld XRF, micro-XRF, and ultra-trace analysis TXRF spectrometers.
