A new approach for the determination of sulphur in food samples by high-resolution continuum source flame atomic absorption spectrometer

The new approach for the determination of sulphur in foods was developed, and the sulphur concentrations of various fresh and dried food samples determined using a high-resolution continuum source flame atomic absorption spectrometer with an air/acetylene flame. The proposed method was optimised and the validated using standard reference materials, and certified values were found to be within the 95% confidence interval. The sulphur content of foods ranged from less than the LOD to 1.5 mg g−1. The method is accurate, fast, simple and sensitive.
