Abstract:The preparation system of matrix reference materials transgenic rice KMD is established. 4 levels of matrix reference materials which contained KMD powder such as 0.5%, 1%, 2%, 5% are prepared by mass ratio. The results show that, the water content of positive KMD powder and negative Xiushui11 powder is 3.288% and 4.039% respectively and the diameter is less than 200 μm. The detection result of labeling gold powder also show that 4 levels of matrix reference materials have well blended. The preparation system of reference materials of KMD is satisfied with matrix reference materials requirements and lay a foundation for the development in the detection and research of long stability and certified value.
