Application Note

Toxic Trace Metals in Edible Oils by Graphite Furnace Atomic Absorption Spectrophotometry


Graphite furnace atomic absorption spectrophotometry (GFAAS) has been widely applied to the determination of trace elements in food due to its selectivity, simplicity, high sensitivity, and its capability for accurate determinations in a wide variety of matrices. Edible oils are generally low in trace element concentrations, however, metals such as arsenic (As), lead (Pb), cadmium (Cd), chromium (Cr), and selenium (Se) can be found and are known for their toxicities which affect the health of consumers.
