Screening for lead contamination in wheat noodles

This datasheet investigates the capabilities of the Epsilon 1, a benchtop energy dispersive X-ray fluorescence spectrometer as a tool for screening lead in wheat noodles. The simple sample preparation along with quick measurements of elements, make the XRF technique an interesting analytical method for the food industry. It allows analysis close to production lines.

The Codex Alimentarius requires a maximum level of lead to be less than 0.2 mg/kg in cereal grains (Codex Standard 193-1995). Five in-house wheat noodle standards were used to set up the calibrations for lead in instant noodles. Five grams of loose powder were weighed into a disposable sample cup for measurement.
