摘要
探讨了样品粉碎粒度对近红外光谱测定结果的影响。在近红外分析仪的定标和测定中,要特别注意对粉碎机和筛网的选择,筛孔直径不能大于1.0mm,同时定标样品和测试样品的粉碎条件应当完全一致。
Effects of sample particle size on the measurement values of NI Reflectance Spestroseopy are investigated. In calibration and measurement, special attention should be given to the choice of grinder and sereen. In order to reduce measurement errors, the diameter of screen mesh should not be larger than 1.0mm and the grinding conditions for calibration samples and test samples should be identical.
