Fast Determination of Multi-Nutrient Elements in Cereals by X-Ray Fluorescence Spectrometry Based on Quantitative Analysis Without Standards |
| |
| Abstract: | Multi-nutrient elements were determined in cereals, using X-ray fluorescence spectrometry based on quantitative analysis without standards. The influence of cereal type, particle size, measuring time and balance for matrix effect correction was studied. Under optimized experimental conditions, the performance of this method was assessed by comparing analysis results with certified reference materials, showing remarkable accuracy and precision especially for wheat and rice samples, which demonstrated the applicability to fast determination of nutrient elements in cereals. |
